+# Building
+## Pre-requisites
+- A bash shell (git bash is sufficient for Windows)
+- [`git`](https://git-scm.com) available in your shell
+- PHP 8.0 or newer available in your shell
+- [`composer`](https://getcomposer.org) available in your shell
+
+## Custom PHP binaries
+Because PocketMine-MP requires several non-standard PHP extensions and configuration, PMMP provides scripts to build custom binaries for running PocketMine-MP, as well as prebuilt binaries.
+
+- [Prebuilt binaries](https://jenkins.pmmp.io/job/PHP-8.0-Aggregate)
+- [Compile scripts](https://github.com/pmmp/php-build-scripts) are provided as a submodule in the path `build/php`
+
+If you use a custom binary, you'll need to replace `composer` usages in this guide with `path/to/your/php path/to/your/composer.phar`.
+
+## Setting up environment
+1. `git clone --recursive https://github.com/pmmp/PocketMine-MP.git`
+2. `composer install`
+
+## Checking out a different branch to build
+1. `git checkout <branch to checkout>`
+2. `git submodule update --init`
+3. Re-run `composer install` to synchronize dependencies.
+
+## Optimizing for release builds
+1. Add the flags `--no-dev --classmap-authoritative` to your `composer install` command. This will reduce build size and improve autoloading speed.
+2. Preprocess the source code by running `build/preprocessor/PreProcessor.php`. Usage instructions are provided in `build/preprocessor/README.md`.
+
+### Note
+Preprocessor requires that the `cpp` (c preprocessor) is available in your PATH.
+
+## Building `PocketMine-MP.phar`
+Run `composer make-server` using your preferred PHP binary. It'll drop a `PocketMine-MP.phar` into the current working directory.
+
+You can also use the `--out` option to change the output filename.
+
+There is a bug in PHP that might cause an error which looks like this:
+```
+Fatal error: Uncaught BadMethodCallException: unable to create temporary file in PocketMine-MP/build/server-phar.php:119
+```
+You can work around it by setting `ulimit -n` to some bigger number, e.g. `8192`, or by updating your PHP version to at least 8.0.3.
+
+## Running PocketMine-MP from source code
+Run `src/pocketmine/PocketMine.php` using your preferred PHP binary.

 # PocketMine-MP Contribution Guidelines
 
+PocketMine-MP is an open source project, and contributions from the community are welcomed, as long as they comply with our quality standards and licensing.
 
-## Creating an Issue
-- If you are reporting a bug:
-  - **make sure that you are using the latest supported version** before opening an issue.
-  - **test it on a clean test server, WITHOUT PLUGINS**, to see if the issue still occurs. If not then it may be a plugin issue. Please also indicate the result of such tests.
-- **[Search the issue tracker](https://github.com/pmmp/PocketMine-MP/issues?utf8=%E2%9C%93&q=is%3Aissue)** to check if anyone has already reported it, to avoid needlessly creating duplicate issues. Make sure you also check closed issues, as an issue you think is valid may already have been resolved.
-- **Do not report plugin issues here.** If your issue is related to a plugin, contact the plugin's original author instead.
-- **Support requests are not bugs.** Issues such as "How do I do this" are not bugs and will be closed. If you need help, please see [here](README.md#discussion) and do not misuse our issue tracker.
-- **No generic titles** such as "Question", "Help", "Crash Report" etc. A good issue report provides a quick summary in the title. If you just got a crash report but you don't understand it, please look for a line starting with `Message`. It summarizes the bug.
-- **Provide information in the issue body, not in the title.** No tags like `[BUG]` are allowed in the title, including `[SOLVED]` for solved issues.
-- **No generic issue reports.** For bugs, it is the issue author's responsibility to provide us an issue that is **trackable, debuggable, reproducible, reported professionally and is an actual bug**.
-<br>Valid issue reports must include instructions how to reproduce the issue or a crashdump/backtrace (unless the cause of the issue is obvious).
-<br>**If you do not provide us with a summary or instructions on how to reproduce the issue, it will be treated as spam and will therefore be closed.**
-<br>In simple words, if the issue cannot be properly confirmed to be valid or lacks required information, the issue will be closed until further information is provided.
-- To express appreciation, objection, confusion or other supported reactions on pull requests, issues or comments on them, use GitHub [reactions](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) rather than posting an individual comment with an emoji only. This helps keeping the issue/pull request conversation clean and readable.
-- If your issue is related to the PocketMine-MP website, forums, etc., please [talk to a human directly](README.md#discussion).
+Code contributions must be submitted using [GitHub Pull Requests](https://github.com/pmmp/PocketMine-MP/pulls), where they will be reviewed by maintainers.
 
+Small contributions (e.g. minor bug fixes) can be submitted as pull requests directly.
 
+Larger contributions like feature additions should be preceded by a [Change Proposal](#rfcs--change-proposals) to allow maintainers and other people to discuss and decide if it's a good idea or not.
 
-## Contributing
-To contribute to the repository, [fork it on GitHub](https://github.com/pmmp/PocketMine-MP/fork), create a branch on your fork, and make your changes on your fork. You can then make a [pull request](https://github.com/pmmp/PocketMine-MP/pull/new) to the project to compare your branch to ours and propose your changes to our repository. We use the Pull Request system to allow members of the team to review changes before they are merged.

+- [About pull requests](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests)
+- [About forks](https://docs.github.com/en/github/collaborating-with-pull-requests/working-with-forks/about-forks)

-### Licensing
-By proposing a pull request to the project, you agree to your code being distributed within PocketMine-MP under the [LGPL license](LICENSE).
+## Other things you'll need
+- [git](https://git-scm.com/)
 
-### Contribution standards
-- **We enforce a very high standard for contributions**. This is because PocketMine-MP and its related projects are used very widely in production. While this might seem like we are being mean at times, **our priority is what is best for PocketMine-MP itself**.
-We try to ensure that our project's codebase is as clean as possible and ensure that only top-quality material makes it through to PocketMine-MP itself.
-- **If a contribution does not meet our standards, changes may be requested or the pull request may be closed.**
+## Making a pull request
+The basic procedure to create a pull request is:
+1. [Fork the repository on GitHub](https://github.com/pmmp/PocketMine-MP/fork). This gives you your own copy of the repository to make changes to.
+2. Create a branch on your fork for your changes.
+3. Make the changes you want to make on this branch.
+4. You can then make a [pull request](https://github.com/pmmp/PocketMine-MP/pull/new) to the project.
 
-### Pull requests
-- **Create a new branch for each pull request.** Do not create a pull request with commits that exist in another pull request.
+## Pull request reviews
+Pull requests will be reviewed by maintainers when they are available.
+Note that there might be a long wait time before a reviewer looks at your PR.
+
+Depending on the changes, maintainers might ask you to make changes to the PR to fix problems or to improve the code.
+**Do not delete your fork** while your pull request remains open, otherwise you won't be able to make any requested changes and the PR will end up being declined.
+
+### Requirements
+The following are required as a minimum for pull requests. PRs that don't meet these requirements will be declined unless updated to meet them.
+
+#### Licensing
+PocketMine-MP is licensed under [LGPLv3 license](LICENSE).
+By proposing a pull request, you agree to your code being distributed within PocketMine-MP under the same license.
+If you take code from other projects, that code MUST be licensed under an LGPL-compatible license.
+
+#### PRs should be about exactly ONE thing
+If you want to make multiple changes, those changes should each be contributed as separate pull requests. **DO NOT** mix unrelated changes.
+
+#### PRs must not include unnecessary/unrelated changes
+Do not include changes which aren't strictly necessary. This makes it harder to review a PR, because the code diff becomes larger and harder to review.
+This means:
+- don't reformat or rearrange existing code
+- don't change things that aren't related to the PR's objective
+- don't rewrite existing code just to make it "look nicer"
+- don't change PhpDocs to native types in code you didn't write
+
+#### Tests must be provided
+Where possible, PHPUnit tests should be written for new or changed code.
+If that's not possible (e.g. for in-game functionality), the code must be tested manually and details of the tests done must be provided.
+**Simply saying "Tested" is not acceptable** and will lead to your PR being declined.
+
+#### Comments and documentation must be written in American English
+English is the shared languages of all current maintainers.
+
+#### Code must be in the PocketMine-MP style
+It's your responsibility to ensure your code matches the formatting and styling of the rest of the code.
+If you use PhpStorm, a `Project` code style is provided, which you can use to automatically format new code.
+You can also use [`php-cs-fixer`](https://github.com/FriendsOfPHP/PHP-CS-Fixer) to format your code.
+
+### Recommendations
+
+- **Do not edit code directly on github.com.** We recommend learning how to use [`git`](https://git-scm.com). `git` allows you to "clone" a repository onto your computer, so that you can make changes using an IDE.
+- **Use an IDE, not a text editor.** We recommend PhpStorm or VSCode.
+- **Create a new branch on your fork for each pull request.** This allows you to use the same fork to make multiple pull requests at the same time.
 - **Use descriptive commit titles.** You can see an example [here](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
 - **Do not include multiple unrelated changes in one commit.** An atomic style for commits is preferred - this means that changes included in a commit should be part of a single distinct change set. See [this link](https://www.freshconsulting.com/atomic-commits/) for more information on atomic commits. See the [documentation on `git add`](https://git-scm.com/docs/git-add) for information on how to isolate local changes for committing.
 - **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.
-- **It is inadvisable to create large pull requests with lots of changes** unless this has been discussed with the team beforehand. Large pull requests are difficult to review, and such pull requests may end up being closed. The only exception is when all features in the pull request are related to each other, and share the same core changes.
-- **You may be asked to rebase your pull request** if the branch becomes outdated and/or if possibly conflicting changes are made to the target branch. To see how to do this, read [this page](https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request).
-- **Details should be provided of tests done.** Simply saying "Tested" or equivalent is not acceptable.
-
-### Code contributions
-- **Avoid committing changes directly on GitHub. This includes use of the web editor, and also uploading files.** The web editor lacks most useful GIT features and **should only be used for very minor changes**. It is immediately clear if the web editor has been used, and if so the PR is more likely to be rejected. If you want to make serious contributions, **please learn how to use [GIT version control](https://git-scm.com/)**.
-- **Do not copy-paste code**. There are potential license issues implicit with copy-pasting, and copy-paste usually indicates a lack of understanding of the actual code. Copy-pasted code is obvious a mile off and **any PR like this is likely to be closed**. If you want to use somebody else's code from a Git repository, **use [GIT's cherry-pick feature](https://git-scm.com/docs/git-cherry-pick)** to cherry-pick the commit. **Cherry-picking is the politer way to copy somebody's changes** and retains all the original accreditation, so there is no need for copy-pasted commits with descriptions like `Some code, thanks @exampleperson`.
-- **Make sure you can explain your changes**. If you can't provide a good explanation of changes, your PR may be rejected.
-- **Code should use the same style as in PocketMine-MP.** See [below](#code-syntax) for an example.
-- **The code must be clear** and written in English, comments included.
+- **Do not make large pull requests without an RFC.** Large changes should be discussed beforehand using the [RFC / Change Proposal](#rfcs--change-proposals) process. Large changes are much harder to review and are more likely to be declined if maintainers don't have a good idea what you're trying to do in advance.
+- **Do not copy-paste code**. There are potential license issues implicit with copy-pasting, and copy-paste usually indicates a lack of understanding of the actual code. Copy-pasted code is obvious a mile off and **any PR like this is likely to be closed**. If you want to use somebody else's code from a Git repository, **use [GIT's cherry-pick feature](https://git-scm.com/docs/git-cherry-pick)** to cherry-pick the commit.
 
 
 **Thanks for contributing to PocketMine-MP!**
 
+## RFCs / Change Proposals
+Change Proposals are issues or discussions which describe a new feature proposal or behavioural change.
+They are used to get feedback from maintainers and the community about an idea for a change, to decide whether or not it's a good idea.
 
+### Submitting an RFC
+RFCs should be submitted using Issues or Discussions.
+RFCs _can_ be submitted as pull requests if you've already written the code, but this is not recommended, since it's not guaranteed that an RFC will pass, in which case your effort would be wasted.
 
-### Code Syntax
+RFCs should include the following:
+- A summary of what you want to change
+- Why you want to change it (e.g. what problems it solves)
+- Alternative methods you've considered to solve the problem. This should include any possible ways that what you want can be done without the change.
 
-It is mainly [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md) with a few exceptions.
+### Voting on RFCs
+Community members can vote on RFCs. This gives maintainers an idea of how popular the idea is.
+Votes can be cast using :+1: and :-1: reactions.
 
-- Opening braces MUST go on the same line, and MUST NOT have spaces before.
-- `else if` MUST be written as `elseif`. _(It is in PSR-2, but using a SHOULD)_
-- Control structure keywords or opening braces MUST NOT have one space before or after them.
-- Code MUST use tabs for indenting.
-- Long arrays MAY be split across multiple lines, where each subsequent line is indented once.
-- Files MUST use only the `<?php` tag.
-- Files MUST NOT have an ending `?>` tag.
-- Code MUST use namespaces.
-- Strings SHOULD use the double quote `"` except when the single quote is required.
-- All code SHOULD have parameter and type declarations where possible.
-- Strict types SHOULD be enabled on new files where it is sensible to do so.
-- All constant declarations SHOULD be preceded by a visibility modifier.
+**Please don't downvote without providing a reason why!**
 
-```php
-<?php
+### Implementing RFCs
+Anyone can write the code to implement an RFC, and submit a pull request for it. It doesn't have to be the RFC author.
 
-declare(strict_types=1);
-
-namespace pocketmine\example;
-
-class ExampleClass{
-
-	public const EXAMPLE_CLASS_CONSTANT = 1;

-			//do things
-		}elseif($firstArgument === "otherValue"){

-					0 => "value1",
-					1 => "value2",

-	public function doStuff(string $stuff) : string{
-		return $stuff;
-	}
-}
-```
-
-<!-- TODO: RFC and voting on the forums instead -->
-### RFC and Voting
-* These are big Pull Requests or contributions that change important behavior.
-* RFCs will be tagged with the *PR: RFC* label
-* A vote will be held once the RFC is ready. All users can vote commenting on the Pull Request
-* Comments MUST use "Yes" or "No" on the FIRST sentence to signify the vote, except when they don't want it to be counted.
-* If your comment is a voting comment, specify the reason of your vote or it won't be counted.
-* After voting has been closed, no further votes will be counted.
-* An RFC will be rejected if less than 50% + 1 (simple majority) has voted Yes.
-* If the RFC is approved, Team Members have the final word on its implementation or rejection.
-* RFCs with complex voting options will specify the vote percentage or other details.
+Implementations should be submitted as pull requests. The pull request description must include a link to the RFC.

+
+## Reporting a Vulnerability
+
+**DO NOT report vulnerabilities on the GitHub issue tracker.**
+GitHub is public and anyone can see the issues you post on the issue tracker, including people who would exploit vulnerabilities for their own gain.
+
+**WARNING: You may put live servers at risk by reporting a vulnerability on the GitHub issue tracker.**
+
+**Contact us** by sending an email to [**team@pmmp.io**](mailto:team@pmmp.io?subject=Security%20Vulnerability%20in%20PocketMine-MP). Include the following information:
+
+- Version of PocketMine-MP
+- Detailed description of the vulnerability (e.g. how to exploit it, what the effects are)
+
+Please note that we can't guarantee a reply to every email.
+
+## FAQ
+### Do you offer a bug bounty?
+No.
+
+### How soon can I expect a fix for a vulnerability I've reported?
+This depends on the nature of the problem. We can't provide any general ETA (nor would it be wise to provide one).
+In general, it depends on when developers have time to look into the problem, how complex the problem is to fix, and how many users it impacts.
+
+When a fix for a severe vulnerability is pushed, a patch release for the target version will usually be released within 24 hours so that users can update.

+# 1.6.1dev-87
+**For Minecraft PE 0.16.0.5 alpha**
+
+**THIS IS A PRE RELEASE. Do not use it in production unless you are sure you know what you are doing.**
+
+Only changes since the 1.6dev tag will be documented here. Changes between 1.4.1 and 1.6dev are far too extensive to document effectively.
+
+## Core
+- New RNG, based on XorShift128 from the php-random library. This fixes issue with repeating terrain on 32-bit systems. _Note however that new generation into existing worlds will not be seamless._
+- Block and Item IDs have been moved to interfaces for better consistency
+- Better method for synchronisation of client/server time (less packet spam)
+- Utils::getRandomBytes() has been deprecated in favour of php7's random_bytes() function.
+- `<player>.dat` saving/reading can now be disabled in `pocketmine.yml` (set `player.save-player-data` to `false`)
+
+## Gameplay/game features
+- Added Flower Pots
+- Containers can now be opened in creative
+- Trapdoors can now be placed without a supporting block
+
+## API
+
+This release has API changes, bumping the version to 2.1.0.
+
+### Entity metadata (0.16)
+
+Many changes have been made to entity metadata. Many true/false data properties are now entity status flags, such as NoAI, NametagVisible and various others. Entity status flags can be set using:
+`$entity->setDataFlag(Entity::DATA_FLAGS, Entity::INSERT_DATA_FLAG_NAME, true/false);`
+
+**Breaking** changes are detailed here. Additions are not documented. https://gist.github.com/dktapps/76b291b7a861762b54f7a8b834389883
+
+**NOTE: It's strongly recommended to use provided API methods where possible instead of tampering with metadata directly.**
+
+### AsyncTask API additions
+- Main thread local storage: Developers can pass any data including objects to the constructor of AsyncTask such that the data can be retrieved after the AsyncTask completes using the new `AsyncTask::fetchLocal()` method, or use the `AsyncTask::peekLocal()` method to get the data without removing it.
+- Progress updates: Developers can use the new `AsyncTask::publishProgress() method and override`AsyncTask::onProgressUpdated()` to handle AsyncTask progress information in the main thread.
+
+Refer to #1 and #100 for details.
+
+### WeakPosition
+
+WeakPosition was added in 1.6.1 to fix bugs with unloading levels which have player spawn points set in them. This type of position holds a level ID instead of a direct reference. Use this when your position may outlive the level it is in.
+
+### Removal of Item/NBT circular dependency
+
+Refer to #121 for details.
+
+### Other
+- Added Player->sendWhisper() (#73).
+- Removed LargeExplodeParticle due to incorrect name - use HugeExplodeParticle. Added HugeExplodeSeedParticle and BlockForceFieldParticle (7314aaf7f7bdae582f674c085c7ae879985bf847)
+
+## Fixes
+- Fixed the infamous hotbar spaz bug
+- Creative/spectator inventory now sends correctly
+- Fixed spectator flight controls
+- Fixed issues with items going past the end of the regular inventory
+- Fixed furnace client crashes
+- Fixed inventory windows for anvils and enchanting tables
+- Fixed kicked for walking on lily pads (#blameshoghicp)
+- Fixed a nasty entity-related memory leak on chunk unload
+- Fixed sleeping players floating above beds and teleportation of sleeping players.
+- Fixed a bug in Level::updateAround() where only one block would update
+- Fixed some slab placement issues (#31)
+- Fixed crash loading 1.11 worlds (#32)
+- Fixed broken `--disable-readline` command-line option (#34)
+- Fixed world unload crash when players have spawnpoints set in that world (#24)
+- Fixed start.sh detection of system PHP binaries (#66)
+- Fixed anvil rotation when placed and variant drops (d696049a0ad5e3b878a8f902e4ef75f19ec8cecc)
+- /timings command is now more verbose about paste errors (#95)
+- Fixed server crash at shutdown when RCON is enabled (#101)
+- Fixed server name is always "Minecraft: PE Server" when running setup wizard (92bd1a755d4b171b687538db83893b9bd9c70420)
+- Fixed CraftItemEvent->getInput() does not return used items (7eb9530346e953d1555623ff871086f85447b6c6)
+- Fixed useless ServerKiller (#122)

+**For Minecraft: Bedrock Edition 1.4.0**
+
+Plugin scheduler rewrite, RCON rewrite, performance improvements, improved idle memory usage
+
+**While this release is nominally not an alpha, it is still not feature complete and does not include all gameplay features. Please do not create issues for missing gameplay features.**
+
+This build has breaking API changes.
+This release is the first to use the new merged versioning system. The PocketMine-MP version and the API version are now one and the same.
+
+Please use our issue tracker to report bugs.
+
+# 3.0.0
+## Core
+### General
+- This release introduces a new dependency library called `Snooze`, which PocketMine-MP utilizes for managing notifications between threads. This library is currently utilized by command reading, RCON and RakLib, allowing faster response times to commands, reduced network latency, and better performance due to lack of need for polling.
+- Fixed race condition causing `ServerKiller` to sometimes kill the server for no reason on shutdown.
+
+### Dependency libraries
+Requires the following libraries:
+- [`pocketmine/raklib` `^0.12.0`](https://github.com/pmmp/RakLib/releases/0.12.0)
+- [`pocketmine/spl` `^0.3.0`](https://github.com/pmmp/SPL/releases/0.3.0)
+- [`pocketmine/binaryutils` `^0.1.0`](https://github.com/pmmp/BinaryUtils/releases/0.1.0)
+- [`pocketmine/nbt` `^0.2.0`](https://github.com/pmmp/NBT/releases/0.2.0)
+- [`pocketmine/math` `^0.2.0`](https://github.com/pmmp/Math/releases/0.2.0)
+- [`pocketmine/snooze` `^0.1.0`](https://github.com/pmmp/Snooze/releases/0.1.0)
+
+These libraries may individually have changes which are not recorded here. See their independent repository releases for their changelogs.
+
+### Async pooling
+- Async workers are now started dynamically when they are needed only, instead of being started immediately on startup. This allows reducing idle memory usage.
+- AsyncPool now appropriately shuts down the workers when instructed to, instead of leaving it up to the ThreadManager to clean it up. This eliminates debug messages of shutting down async workers on server shutdown.
+- Default maximum async worker memory limit has been lowered from 1024MB to 256MB.
+- Async workers are now started using the options `PTHREADS_INHERIT_CONSTANTS | PTHREADS_INHERIT_INI`, which reduces idle memory wastage and works around some bugs in pthreads.
+
+### Entities
+- Fixed entities not being despawned when flagged, if they weren't scheduled for an update.
+
+### Levels
+- Seed handling is now always consistent between `pocketmine.yml` and `server.properties`.
+- Fixed generation bugs in imported LevelDB worlds where the classpath was saved into level.dat.
+- Generators for levels are no longer created on the main thread, reducing memory usage.
+
+### Plugins
+- Plugin data is now stored under `<data dir>/plugin_data` by default on new installations, instead of in `<plugins dir>`. This behaviour does not affect existing installations by default - if you want to enable it, set `plugins.legacy-data-dir` to `false` in `pocketmine.yml`.
+
+### RCON
+RCON has been almost completely rewritten in this release.
+- Now event-driven (using Snooze) instead of poll-based, improving performance.
+- Fixed segmentation fault when stopping the server with RCON enabled.
+
+## API
+**WARNING: Dependency library API changes are not listed here. See their individual release notes for changes (linked above in the Core section).**
+
+### API versioning changes for plugins
+The way that the API versioning is done has changed. Now the API version is synonymous with the PocketMine-MP version.
+Plugin compatibility is determined by the following:
+- Take the base version, and strip any metadata (everything after the `+` sign, for example `3.0.0+dev.1191` becomes `3.0.0`).
+- Assert that:
+  - The major versions is the same
+  - The server's minor version is greater than or equal to the plugin's
+  - The server's patch version is greater than or equal to the plugin's
+
+Currently there is no support for locking version by metadata, although this could be implemented if it is a wanted feature.
+
+### General
+- `Server->getCodename()` and `\pocketmine\CODENAME` have been removed.
+- Added API method `Server->getTickSleeper()`, which returns a `\pocketmine\snooze\SleeperHandler` instance.
+- `Server->getIp()` now returns `0.0.0.0` if not set.
+
+### Block
+- Added `Block->getXpDropForTool()`.
+
+### Entity
+- Calling `scheduleUpdate()` on an `Entity` after it has been `close()`d will now cause an exception to be thrown.
+- `Entity->motionX`, `Entity->motionY` `Entity->motionZ` have been removed in favour of an `Entity->motion` `Vector3` field. This also applies for the `lastMotion` fields.
+- `Entity->isInsideOfWater()` has been renamed to `isUnderwater()`.
+
+### Events
+- Added support for `@softDepend` annotation on event handlers, which allows the event handler to not be registered if the dependency plugin is not loaded.
+- Added support for `@notHandler` annotation for `Listener` methods to indicate that such methods are not event handlers.
+- Typehints have been applied to the events API to PHP 7.2 standards.
+- Fixed preventing effect expiry using `EntityEffectRemoveEvent` not being reflected on the client.
+- `EntityDamageEvent` API has significant changes. The general purpose of this is to split up base damage from modifiers.
+  - Added methods `getBaseDamage()`, `setBaseDamage()`, `getOriginalBaseDamage()`, `getModifiers()`, `getOriginalModifiers()`
+  - `setDamage()` renamed to `setModifier()`, and type parameter is now mandatory
+  - `getDamage()` renamed to `getModifier()`, and type parameter is now mandatory
+  - `getOriginalDamage()` renamed to `getOriginalModifier()`, and type parameter is now mandatory
+  - Removed `MODIFIER_BASE` constant
+  - Constructors now accept: `float baseDamage`, `float[] modifiers` instead of just `float[] modifiers`
+- Added `BlockBreakEvent->getXpDropAmount()` and `BlockBreakEvent->setXpDropAmount()`.
+
+### Inventory
+- `InventoryTransaction->getCreationTime()` has been removed.
+- `EntityInventoryChangeEvent` and `EntityArmorChangeEvent` are no longer fired during entity inventory intialization.
+
+### Item
+- Methods `isPickaxe()`, `isAxe()`, `isSword()`, `isShovel()`, `isHoe()`, `isShears()` have been removed. These should be replaced with `instanceof` checks for the relevant classes.
+- Removed `Item->useOn()`. This has been superseded by new methods used for handling durability changes.
+- Added hooks `Item->onDestroyBlock()` and `Item->onAttackEntity()`. These are called when a player uses the item to destroy a block or attack an entity respectively. This is used in the core code for updating durability.
+- `Item->pop()` now accepts an optional count parameter.
+- `Enchantment` now has separated primary items (which can be enchanted directly) and secondary items (which can be enchanted on an anvil). The constructor of `Enchantment` has been updated to reflect this.
+  - Removed `Enchantment->getSlot()` and `Enchantment->hasSlot()`.
+  - Added `Enchantment->getPrimaryItemFlags()`, `Enchantment->hasPrimaryItemFlag()`, `Enchantment->getSecondaryItemFlags()` and `Enchantment->hasSecondaryItemFlag()`
+
+### Level
+- `Biome` classes have been moved to `pocketmine\level\biome` namespace. This is in preparation for future work on Levels which requires biome information (such as weather conditions).
+- `WeakPosition` has been removed.
+- Added `Level->getBiome()`.
+- `Level->getSafeSpawn()` now always returns a `Position` instance.
+- `Level->getBlockExtraData()` and `Level->setBlockExtraData()` have been removed (as well as their associated `Chunk` methods).
+- `ChunkManager->isInWorld()` now accepts integers instead of floats.
+- Added `SubChunkIteratorManager->invalidate()`.
+
+#### Generator
+- `BiomeSelector` has been refactored to make it simpler and more robust.
+- Generator-management methods `registerDefaultGenerators()`, `addGenerator()`, `getGeneratorList()`, `getGenerator()`, and `getGeneratorName()` have been moved from `Generator` to a new `GeneratorManager` class.
+- Static noise functions in the `Generator` base class have been moved to `Noise` instance methods.
+- Added static method `Generator::convertSeed()`, which converts an int or string into a numeric seed for generation.
+
+### Network
+- `SourceInterface->process()` no longer returns a value.
+
+### Plugin
+- `PluginBase->getResources()` now returns an associative array where the index is the path to the resource relative to the plugin's `resources` directory.
+- `PluginLoader`s have been almost completely rewritten to make them simpler and more robust.
+  - `PluginManager->registerInterface()` does not return anything, and now accepts a `PluginLoader` instance instead of a `string`.
+  - `PluginLoader`:
+    - `getPluginFilters()`, `enablePlugin()` and `disablePlugin()` are removed.
+    - `loadPlugin()` responsibilities are now solely confined to doing whatever is necessary to make the plugin's classes visible by the server, and does not emit log messages or check for data directories.
+    - Added method `getAccessProtocol()` which determines what prefix to apply to the plugin path to access the files inside it (for example `phar://`).
+  - `PluginBase->init()` and `PluginBase->isInitialized()` have been removed.
+  - `Plugin` interface now declares a signature for the constructor which implementations must comply with.
+  - `Plugin` interface now declares `setEnabled()`.
+- It is now possible to create a custom `Plugin` implementation without requiring a custom `PluginLoader`.
+
+### Scheduler
+This release features major changes to how plugin task scheduling works.
+- Removed `Server->getScheduler()`. All plugins now have their own scheduler which is accessible using `Plugin->getScheduler()`. Aside from being syntactically more concise and pleasant, this also allows much more effective management of tasks when plugins are disabled.
+- Removed `PluginTask` class, because it's now unnecessary. Previously it was required to allow the server to delete tasks associated with a plugin when the plugin was disabled. With plugin-owned schedulers, this is no longer a requirement. Plugins may now utilize the `Task` class as a base if they like.
+- Added `Server->getAsyncPool()`. Since the global scheduler does not exist any more, it does not manage the server's `AsyncPool` any more. Additionally, `ServerScheduler` was previously bloated by a lot of `AsyncTask` related methods, which are now not necessary because direct access to `AsyncPool` is granted instead.
+- `ServerScheduler`:
+  - `ServerScheduler` has been renamed to `TaskScheduler` since it is now a general-purpose task scheduler which is non-dependent on the user. This allows much greater flexibility and also makes it possible to unit-test.
+  - All `AsyncTask`/`AsyncPool` related methods have been removed - the task scheduler does not manage the async pool anymore.
+    - Calls to `Server->getScheduler()->scheduleAsyncTask()` should be replaced with `Server->getAsyncPool()->submitTask()`.
+    - Calls to `Server->getScheduler()->scheduleAsyncTaskToWorker()` should be replaced with and `Server->getAsyncPool()->submitTaskToWorker()`.
+
+### Tile
+- Calling `scheduleUpdate()` on a `Tile` after it has been `close()`d will now cause an exception to be thrown.
+- Tile NBT is now ephemeral and is not retained after creating the tile.
+  - `Tile->namedtag` has been removed.
+  - `Tile->saveNBT()` now returns a new `CompoundTag` containing saved data.
+  - Added new protected methods `Tile->readSaveData()` and `Tile->writeSaveData()`. These should be overridden to add or read tile-specific data, instead of overriding `saveNBT()` and `__construct()`.
+
+### Utils
+- Added `MainLogger->getFormat()` and `MainLogger->setFormat()` to allow manipulating console output format.
+
+## Gameplay
+### General
+- Fixed a range of block collision issues stemming from off-by-one errors when fetching areas.
+
+### Blocks
+- Fixed a crash which occurred when leaving a bed which was broken and replaced during sleep.
+- Fixed dark oak and acacia saplings growing into oak trees - now they will not grow at all (they need to be implemented).
+- Saplings now take light level into account when trying to grow.
+- Ores and other blocks now drop experience when broken with an appropriate tool.
+
+### Entities
+- Fixed dropped items not being correctly destroyed by fire, cacti and other damage sources.
+
+### Generation
+- Grass no longer generates as the top layer of ground cover in river biomes.
+- Ocean biomes now use gravel instead of grass+dirt for ground cover.
+- Reduced maximum elevation of plains biomes to make them less bumpy.
+- Snow layers and other can-be-flowed-into blocks no longer generate underwater.
+
+### Items
+- Buckets are no longer able to delete any block by replacing it with water.
+- Dried Kelp, Bleach, Nautilus Shell and Heart of the Sea items are registered (although crafting recipes for these are not yet available).
+- Implemented `Vanishing` enchantment.
+- Implemented Totems.
+
+### World
+- Fixed explosions sometimes leaving behind air blocks with non-zero damage values.
+
+# 3.0.1
+- Fixed error when players move things around in the crafting grid after plugins cancel `PlayerInteractEvent` on crafting tables.
+
+# 3.0.2
+- Fixed memory dumps not showing private properties of parent classes.
+- Fixed a memory leak when cancelling all tasks in the `TaskScheduler`.
+- Fixed scheduled task timings showing `Unknown` as the plugin name.
+
+# 3.0.3
+- Fixed possible crash in Sign when placed by a plugin.
+- Fixed slightly-damaged and very-damaged anvils dropping incorrect items.
+- `Living->applyPostDamageEffects()` is no longer called if the mob died from an attack.
+- Cooldown for mob attack is now reset prior to applying post-damage effects.
+- Added constant `ItemIds::MUTTON` to resolve crashes using PC worlds.
+- Fixed emerald ore not dropping XP when broken with a valid tool.
+- Fixed mobs getting crazy vertical knockback if attacked while airborne.
+- Fixed XP orbs continuing to follow dead players.
+
+# 3.0.4
+- Fixed RCON spamming the console when a client does not disconnect correctly.
+- Fixed dropping chunk cache unnecessarily when no blocks need to be updated on a chunk.
+- Fixed outdated block updates getting sent on chunks replaced using `setBlock()`.
+
+# 3.0.5
+- Fixed not being able to place blocks where a player died and has not yet respawned (#2265).
+- Fixed mob death animation not being played when `Entity->kill()` is called directly or `/kill` is used.
+- Fixed viewers of different halves of double chests not seeing changes made by viewers who opened the other half (#2261).
+- Fixed bugs setting items into wrong indexes when double chest halves have differently sized inventories.
+- Fixed `getConfig()` crashing when called when the plugin's data directory doesn't exist.
+- Fixed a possible exploit with keychain signing for XBL login.
+
+# 3.0.6
+- Fixed invalid keys in `.properties` config files being considered as invalid strings.
+- Fixed whitespace between key and value `key = value` being invalid in `.properties` config files.
+- Fixed a bug in exception message when an invalid permission type is written for a command in plugin.yml.
+- Properly fixed newline issues when parsing event handler annotations - `@notHandler` will now work as expected when CRLF line endings are used.
+- Fixed `PluginManager->registerEvents()` registering functions as event handlers declared by parent classes which are not `Listener` instances (#2293).
+
+# 3.0.7
+- Fixed setting spawn points in un-generated chunks causing the player to fall out of the world.
+- Fixed spawn protection deactivating when there are no ops set (this was an unwanted/unexpected feature, so it's considered a bug).
+- Fixed cursor items not getting dropped when closing the inventory or dying.
+- Fixed more issues with blocks with invalid metadata appearing as update! blocks.
+- `Entity->setNameTagAlwaysVisible()` now works (although nametags will still not be shown if the entity is invisible, due to a behavioural change in Minecraft PE).
+- Fixed errors passing zero motions to projectiles in some cases.
+
+# 3.0.8
+- Fixed player on-ground state not updating when moving horizontally. This allowed fly hacks with the built in anti-cheat, and also affected some third party anti-cheat plugins due to the effect on `inAirTicks`.
+- Fixed knockback. PC 1.9-style knockback was mistakenly introduced in 3.0.3. This has now been reverted back to the old 1.8-style behaviour.
+
+# 3.0.9
+- Cleaned up odd behaviour of `/kill` due to old broken code.
+- Fixed patch level check for plugin APIs not allowing lesser patch versions on greater minor versions.
+- Fixed `/timings paste`. This now reports directly to the timings host instead of using Ubuntu Pastebin.
+- Minor code cleanups in various places.
+- Zip resource packs will now give slightly less useless errors - errors for broken manifest have been separated from those with fields missing, and now reports why decoding failed if it failed.
+
+# 3.0.10
+- Syntax error crashdumps will no longer be reported to the crash archive.
+- Chunk sending is now fault-tolerant. Before this release, any error on a worker during async chunk sending (such as memory errors caused by pthreads) would cause that chunk to never get sent, resulting in invisible and missing chunks. Levels will now attempt to retry chunk prepare when a task crashes, which should fix most invisible chunk bugs.
+- `MainLogger` now logs exception stack traces in a synchronized block to ensure that they are coherent when log messages are emitted from multiple threads at once.
+- `AsyncTask->isCrashed()` now returns `true` if a fatal error occurred during the task execution.
+
+# 3.0.11
+- `DropItemAction` will now consider itself invalid if attempting to drop a null item.
+- Fixed leaking globally broadcasted Level packets when no players are on the server.
+- Fixed title bar not being cleared on server stop on some terminals.
+- Fixed `FallingBlock` saving corrupted data.
+- Fixed the structure of `GuiDataPickItemPacket`.
+- Cleaned up some code in `OfflinePlayer`.
+- Splash potions no longer apply effects to dead (but not yet respawned) players.
+- Coal ore no longer drops XP when mined with a silk touch tool.
+- Item entities now cannot be picked up when a negative pickup delay is used.
+
+# 3.0.12
+- `Config` keys which are considered bools by YAML 1.1 will no longer be transformed into 1 or 0.
+- Fixed painting motives not getting saved.
+- Fixed cacti spewing items when placed in some invalid locations.
+- Fixed entity fire damage not applying in the void.
+- Fixed entities not getting updated appropriately in some conditions.

+# 3.12.0
+- Added support for Minecraft: Bedrock Edition 1.14.60
+- Removed compatibility with 1.14.0-1.14.30
+
+# 3.12.1
+- Fixed parsing of single-line doc comments for event handlers, e.g. `/** @ignoreCancelled */` should now work correctly.
+- The server will no longer crash on failure to load `level.dat` contents, but will gracefully shutdown instead without producing a crashdump.
+- Fixed some bugs in login verification that could cause undefined behaviour.
+- Fixed item-use behaviour when sneaking - sneaking and clicking a block with an empty hand, and sneaking and using an item, both now follow vanilla behaviour.
+- `start.sh` will now work on platforms where `/bin/bash` is not available, as long as `/usr/bin/env` knows where bash is.
+
+# 3.12.2
+- Fixed permission default timings not being reported in timings reports (they were never stopped, only started).
+- Resource packs with a directory tree like `pack.zip/MyPack/manifest.json` are now supported. Note that the manifest closest to the root will be used.
+- Fixed `SkinImage` height and width being inverted at the protocol layer.
+- Fixed blocks being able to be placed inside the spawn protection radius by clicking the side of a block outside the radius.
+- Fixed server crash when `network.compression-level` is overridden by a CLI parameter.
+- Fixed moving entities spawning themselves to players registered on chunks when the players haven't received the chunk yet.
+- Cocoa pods now drop cocoa beans when broken instead of the block itself.
+
+# 3.12.3
+- Core code is now analyzed using PHPStan level 8 (using baselines). While not all the code is level 8 compliant, this does mean that new code will be held to a higher standard, ensuring quality going forwards.
+- Players no longer burn when melee-attacked by other players. (vanilla parity)
+- Arrows shot by burning players are no longer on fire. (vanilla parity)
+- Fixed a crash that could occur with plugins on Unix filesystems that had backslashes in their names.
+- Cleaned up a whole bunch of unknowns in the protocol layer. Many new constants have been added.
+- Fixed player walking sounds.
+- Default generation queue size has been raised to 32 (previously 8). The previous default was selected in a time when PHP was much less performant than it is today, and in today's world it just needlessly slows things down.
+- Double plants are now burned away by fire.
+- Snow layers can now be stacked. (vanilla parity)
+- Resource pack sending chunk size has been reduced to 128 KB (previously 1 MB). This change was made after analyzing the effects that larger pack chunk sizes have on RakNet. Given the technical evidence, a smaller size, while slightly less bandwidth-efficient, should be more manageable for RakNet due to lower split reassembly overhead and reduced memory pressure.
+- Fixed "switching" (an exploit often complained about by PvP players). Now, the previous damage is subtracted from current damage when an entity is attacked while on cooldown. This means that attacking with a wooden sword and then diamond sword while attack cooldown is active will only deal as much damage as the diamond sword would have, instead of the combined total. This can be controlled using the `EntityDamageEvent::MODIFIER_PREVIOUS_DAMAGE_COOLDOWN` modifier. (vanilla parity)
+- Fixed projectiles knocking mobs back in unexpected directions on collision.
+- Fixed inventories not being synchronized on failed inventory transactions.
+- Vector3s decoded from packets are no longer rounded directly. Instead, the player movement handler takes responsibility for rounding the coordinates to prevent anti cheat doing something it's not supposed to.
+- `mobflame` particle can now be spawned using the `/particle` command.
+- Fixed several internal errors that could occur while modifying writable books.
+- Fixed swapping writable book pages not working in some cases.

+**For Minecraft: Bedrock Edition 1.14.60**
+
+This is a feature release, containing various minor API additions, deprecations and a few minor features.
+
+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.
+
+**WARNING: If your plugin uses the protocol, you're not shielded by API change constraints.** You should consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you do.
+
+# 3.13.0
+## Core
+- PHP 7.3.0 or newer is now required.
+- Player movement processing has been revamped. It's now more tolerant of network lag and doesn't have as many problems with falling.
+
+## User Interface
+- `/time` now supports additional aliases `noon`, `sunset`, `midnight` and `sunrise`.
+- Removed warnings when a plugin registers a handler for a deprecated event. Since this warning is developer-focused, and too specific to be useful, it just caused annoyance and confusion to users who didn't know what it meant.
+
+## API
+### General
+- It's now possible to require a specific operating system using the `os` directive in `plugin.yml`. More information about this directive can be found in the [developer documentation](https://github.com/pmmp/DeveloperDocs).
+
+### Player
+- `Player->resetItemCooldown()` now accepts a second parameter, allowing plugins to provide a custom duration.
+- The following methods have been deprecated and have recommended replacements:
+  - `Player->addTitle()` -> `Player->sendTitle()`
+  - `Player->addSubTitle()` -> `Player->sendSubTitle()`
+  - `Player->addActionBarMessage()` -> `Player->sendActionBarMessage()`
+
+### Event
+- The following methods have been deprecated:
+  - `EntityDespawnEvent->getType()`
+  - `EntityDespawnEvent->getPosition()`
+  - `EntityDespawnEvent->isCreature()`
+  - `EntityDespawnEvent->isHuman()`
+  - `EntityDespawnEvent->isProjectile()`
+  - `EntityDespawnEvent->isVehicle()`
+  - `EntityDespawnEvent->isItem()`
+  - `EntitySpawnEvent->getType()`
+  - `EntitySpawnEvent->getPosition()`
+  - `EntitySpawnEvent->isCreature()`
+  - `EntitySpawnEvent->isHuman()`
+  - `EntitySpawnEvent->isProjectile()`
+  - `EntitySpawnEvent->isVehicle()`
+  - `EntitySpawnEvent->isItem()`
+- Added the following API methods:
+  - `EntityDeathEvent->getXpDropAmount()`
+  - `EntityDeathEvent->setXpDropAmount()`
+- `PlayerDeathEvent::__construct()` now accepts a fourth (optional) parameter `int $xp`.
+- `EntityDeathEvent::__construct()` now accepts a third (optional) parameter `int $xp`.
+
+### Inventory
+- The following classes have been deprecated:
+  - `Recipe`
+- The following methods have been deprecated:
+  - `CraftingManager->registerRecipe()`
+  - `Recipe->registerToCraftingManager()` (and all its implementations)
+
+### Item
+- New `Enchantment` type ID constants have been added.
+- `ItemFactory::fromStringSingle()` has been added. This works exactly the same as `ItemFactory::fromString()`, but it has a return type of `Item` instead of `Item|Item[]` (more static analysis friendly).
+
+### Level
+- Added the following API methods:
+  - `Position->getLevelNonNull()`: this is the same as `Position->getLevel()`, but throws an `AssumptionFailedError` if the level is null or invalid (more static analysis friendly).
+  - `Level->getTimeOfDay()`
+- The following constants have been changed:
+  - `Level::TIME_DAY` now has a value of `1000`
+  - `Level::TIME_NIGHT` now has a value of `13000`
+- Added the following constants:
+  - `Level::TIME_MIDNIGHT`
+  - `Level::TIME_NOON`
+- The following types of particles now accept optional `Color` parameters in the constructor:
+  - `EnchantParticle`
+  - `InstantEnchantParticle`
+
+### Network
+- Added the following API methods:
+  - `RakLibInterface->setPacketLimit()`
+
+### Scheduler
+AsyncTask thread-local storage has been improved, making it simpler and easier to use.
+- `AsyncTask->fetchLocal()` no longer deletes stored thread-local data. Instead, the storage behaves more like properties, and gets deleted when the AsyncTask object goes out of scope.
+- `AsyncTask->peekLocal()` has been `@deprecated` (use `fetchLocal()` instead).
+- Notices are no longer emitted if an async task doesn't fetch its locally stored data.
+- The following methods have been deprecated:
+  - `AsyncTask->getFromThreadStore()` (use its worker's corresponding method)
+  - `AsyncTask->saveToThreadStore()` (use its worker's corresponding method)
+  - `AsyncTask->removeFromThreadStore()` (use its worker's corresponding method)
+
+### Utils
+- The following functions have been deprecated and have recommended replacements:
+  - `Utils::getMemoryUsage()` -> split into `Process::getMemoryUsage()` and `Process::getAdvancedMemoryUsage()` (not 1:1 replacement!!)
+  - `Utils::getRealMemoryUsage()` -> `Process::getRealMemoryUsage()`
+  - `Utils::getThreadCount()` -> `Process::getThreadCount()`
+  - `Utils::kill()` -> `Process::kill()`
+  - `Utils::execute()` -> `Process::execute()`
+- Added the following constants:
+  - `Utils::OS_WINDOWS`
+  - `Utils::OS_IOS`
+  - `Utils::OS_MACOS`
+  - `Utils::OS_ANDROID`
+  - `Utils::OS_LINUX`
+  - `Utils::OS_BSD`
+  - `Utils::OS_UNKNOWN`
+- Added the following API methods:
+  - `Config->getPath()`
+  - `Utils::recursiveUnlink()`
+  - `Terminal::write()`
+  - `Terminal::writeLine()`
+
+# 3.13.1
+- Fixed issues with `server.lock` not being unlocked on some platforms. Now, the server explicitly releases it before exiting.
+- `/timings` now sends a usage message when using an unknown subcommand. Previously, it would just give no output.
+- `/whitelist` now sends a usage message when using an unknown subcommand. Previously, it would just give no output.
+- The output from `/timings` is now broadcasted on the `pocketmine.broadcast.admin` broadcast channel for auditability, similarly to other operator commands.
+- Fixed `ShapedRecipe` deprecation warning on PHP 7.4.
+- Fixed some potential crashes with Bedrock worlds when chunk data is corrupted or missing.
+- Fixed a bug in region handling that caused region loaders to overestimate the amount of space used in the file. This resulted in an up to 4 MB growth of the file size every time the region was reloaded after writing a chunk.
+- Region handlers now try to reuse free space in region files before putting the chunk at the end of the file. Previously, space was only reused if the new version of the chunk was <= the size of the old. This fixes endless growth of region files.
+- Regions now never directly overwrite old copies of chunks when saving; instead they try to find an alternative location (preferring unused space within the file first). This avoids chunk corruption on power failure (the old copy of the chunk won't be damaged, so a rollback might occur instead), and as happy side effect, causes oversized regions to gradually shrink towards their most packed state over time, saving disk space.
+- Regions now have a hard size cap at 64 GB. This is because the header pointers will overflow beyond 64 GB (besides, a normal region shouldn't be this big anyway).
+- Fixed a crash that could occur when reading a too-short region header.
+- `VerifyLoginTask` now only copies JWTs to verify instead of the entire login packet. This reduces the amount of data copied between threads, improving performance.
+- Added a fast-fail check to `VerifyLoginTask` by checking the JWT header's `x5u` against the expected public key.
+- `Skin->validate()` now throws `InvalidSkinException` instead of `\InvalidArgumentException`.
+- A debug message is now logged when a player is kicked for having an invalid skin, giving a brief line of detail why.
+- Fixed players not being kicked for having an invalid `resourcePatch`.
+- Fixed block meta value of cake being preserved when using pick-block.
+- Fixed explosions not fully destroying multi-block objects like beds and doors.

+- All skins are now trusted, bypassing the client-side trusted skin setting. Note that this means that NSFW skin filtering will **not** apply.
+- Fixed projectile motion being altered by ladders.
+- Fixed client-sided crashes when pressing E repeatedly very quickly on a high-latency connection.
+- `/plugins`, `/whitelist list`, `/banlist` and `/list` now show output in alphabetical order.
+- Some `pocketmine\event` APIs which accept arrays now have more robust type checking, fixing type errors caused by plugin input occurring in core code.
+- `Attribute::getAttributeByName()` is now aware of the `minecraft:lava_movement` attribute.

+# 3.14.2
+- Exception stack traces are now logged as CRITICAL. It's hoped that users will recognize that they are just as important as the error message and not leave them out when asking for help with errors on Discord.
+- `TaskScheduler` no longer accepts tasks that already have a handler. This fixes undefined behaviour which occurs when scheduling the same task instance twice, but it does break plugins such as **MyPlot** which unintentionally used this buggy behaviour.
+- Players will now correctly receive the needed number of spawn chunks if they are teleported between `PlayerLoginEvent` and `PlayerJoinEvent`. This fixes a bug that could occur when teleporting players in delayed tasks between login and join.
+- `PlayerRespawnEvent->setRespawnPosition()` now throws an exception if the provided `Position` has an invalid world associated with it (null or unloaded).
+- Fixed a crash that occurred when stats reporting was enabled.
+
+# 3.14.3
+- Fixed deprecation error when running `/whitelist list` on PHP 7.4.
+- Fixed podzol breaking animation being incorrect (incorrect hardness).
+- `Entity::getSaveId()` now reports the class name in the message thrown for unregistered entities.
+- Fixed `CraftingManager->validate()` producing different results when called multiple times for the same transaction.
+- Fixed various issues with batch-crafting items using the recipe book and shift-clicking.
+- `tests/plugins/PocketMine-DevTools` submodule has been renamed to `tests/plugins/DevTools`.

+- Fixed various PHP 7.4 compatibility issues in Composer dependencies (primarily callback-validator).

+- Fixed blocks not getting updated properly on explosions.
+- Fixed `BlockGrowEvent` not being called when sugarcane grows.
+- Potato crops now drop poisonous potatoes when harvested.

+- Players no longer get pullbacks when sprinting on slabs, stairs and various other blocks when `player.anti-cheat.allow-movement-cheats` is set to `false`. (This bug has been around for over 5 years, so many of you will be used to its existence.)
+- Fixed entity collision box calculation not taking clip distance into account.
+- Entities now step up the correct height of the target block, instead of jumping into the air 0.6 blocks and falling back down.
+
+# 3.15.2
+- Fixed issues with preloading `SubChunk`.
+- `/gc` and automatic garbage collection will now release unused heap blocks back to the OS. Previously, the PHP process might hold onto these blocks indefinitely even when not used, causing elevated real memory usage.
+- Added some documentation to `FurnaceBurnEvent`.
+
+# 3.15.3
+- Fixed fall damage accumulation over continuous knockbacks (e.g. combo attacks in PvP).
+- Fixed a bug in `Human->addXp()` that would cause a crash when saving player data.
+- `Human->addXp()` will no longer modify the target's total XP if `PlayerExperienceChangeEvent` was cancelled.
+- `AsyncPool->getTaskQueueSizes()` has been added to allow external detection of async pool overload. This is planned to be implemented as a core feature in the future, but it hasn't been done yet.
+- `BaseInventory->canAddItem()` behaviour now matches `addItem()` by considering the max stack size of the given item.
+- Fixed a bug in generator options handling for worlds loaded via `pocketmine.yml`. This fix has the following side effects:
+  - It's now possible to provide generator options as an `options` key when loading a world via `pocketmine.yml`.
+  - If generator options are not provided, the options from `server.properties` will be used, instead of using an empty preset. (It's not clear whether this is desired behaviour, but it was clearly intended, since there is code to do this which was broken until this release. As such, this behaviour is subject to change in the future.)
+- Fixed a bug in region-based world loading where some files without filename extensions and names containing a region filename extension (e.g a file named `amca` in a McRegion world) would cause the world not to load. These files are now ignored.
+- Default network compression level has been lowered to 6, due to level 7 being 25% more expensive for only a marginal improvement in bandwidth.
+- Fixed a performance issue with chunk requesting when players trigger chunk generation on first join.
+- Setup wizard will now always show IP information, even if the user chose to skip the setup wizard when prompted. (This doesn't affect `--no-wizard` in any way.)
+- `Maximum memory (system)` is no longer reported in `/status` due to having a misleading output (it was the same as the current memory usage).
+- The `Player Chunk Send` timer on timings reports now actually reports measurements of chunk sending, not chunk loading.
+- A new parent timer `World Load` has been added to timings reports, which aggregates timings from `syncChunkLoad` and subtimings from all worlds.

+**For Minecraft: Bedrock Edition 1.6.0**
+
+This is a minor feature release, including support for Minecraft Bedrock 1.6.0, some new minor gameplay features and some API deprecations and additions.
+
+### Note
+Plugins compatible with any previous 3.x.y version will also run on this build and do not need API bumps.
+
+However, some API features have been deprecated in this version. Plugin developers do not need to do anything about these deprecations immediately, however they may raise harmless warnings if used.
+
+Features marked **`@deprecated`** are **recommended** not to be used, but will continue to work for any future 3.x.y versions. They will be removed in the next major release (4.0).
+
+# 3.2.0
+### Core
+- `Level` generators are now registered only when needed instead of as soon as a worker starts. This drastically reduces memory consumption on servers with lots of workers.
+- Async workers are now garbage-collected along with everything else on the default schedule. Idle workers with 0 queued tasks will be shutdown and removed from the pool to reduce memory usage.
+- UPnP error messages are now more informative of troubleshooting steps.
+- Errors are no longer caught in cases where they are unrecoverable.
+
+### API
+#### Entity
+- Arrow pickup mode can now be controlled via `Arrow->setPickupMode()`. This accepts one of three `Arrow` constants: `PICKUP_NONE`, `PICKUP_ANY`, `PICKUP_CREATIVE`.
+- Added new API methods `Projectile->getBaseDamage()` and `Projectile->setBaseDamage()`.
+- Added new API methods `Entity->getScoreTag()` and `Entity->setScoreTag()`.
+
+#### Events
+- The `Listener` interface has now received in-depth documentation about its behaviour and uses. See the top of the `Listener` class to read it.
+- It is now possible to declare `@ignoreCancelled` on an event handler without specifying `true` or `false`. If no value is found, `true` will be assumed.
+- `ServerCommandEvent` and `RemoteServerCommandEvent` are now **`@deprecated`** and their usage discouraged. A new generic `CommandEvent` has been introduced in its place, which allows capturing commands from any type of command sender. This was done in response to difficulties of code duplication when wanting to intercept commands from both console and players.
+- `EntityDamageEvent`
+  - Added `MODIFIER_WEAPON_ENCHANTMENTS` constant for attack damage bonuses due to enchantments like Sharpness.
+  - Added new API methods `getAttackCooldown()` and `setAttackCooldown()` to allow controlling Living entities attack cooldown times (default 10 ticks).
+- `PlayerDeathEvent`: Added new static method `deriveMessage()`.
+- `PlayerKickEvent`: Added new method `setReason()`.
+
+#### Forms
+- Added a new `pocketmine\form\Form` interface. Implementing this interface permits custom form implementations to make use of `Player->sendForm()`, eliminating the need to handle packets directly and also solving the form ID collision problem.
+
+#### Items
+- `Item` and `ItemFactory` now support negative item IDs (needed for future extended blocks support).
+- Updated `ItemIds` interface with new constants.
+
+#### Permission
+- Added a new `PermissionManager` class which encapsulates all of the permission-management functionality originally bloating `PluginManager`. The API is identical to that of `PluginManager`'s permission API. All methods moved to `PermissionManager` have **`@deprecated`** redirects remaining behind in `PluginManager`, which will be removed in the next major release (4.0).
+
+#### Plugin
+- `PluginBase->getConfig()` will now automatically save the default config if it does not already exist.
+- Plugin data directories will now be automatically created on plugin load, eliminating the need for boilerplate `@mkdir($this->getDataFolder())` calls at the top of every plugin.
+
+#### Tile
+- `Tile::createNBT()` will now throw a `BadMethodCallException` when called directly.
+
+#### Utils
+- `Utils::getURL()`, `Utils::postURL()`, `Utils::simpleCurl()` and `Utils::getIP()` have been moved to a new `pocketmine\utils\Internet` class. The original methods are **`@deprecated`** and will be removed for the next major version (4.0).
+- Removed the ability for `Config` to be asynchronously saved. This was discussed for removal because of various problems that it causes. It was deemed not worth fixing since `Config` saving should not be significant enough to cause problems anyway. See #2298 for details.
+
+#### Server
+- Deprecated `level` parameter of `findEntity()`. This parameter was premature optimization. Code using it will continue to work as before.
+
+### Gameplay
+#### General
+- Air bubbles are now regenerated at the same speed as vanilla UpdateAquatic, instead of instantly when leaving water.
+- Implemented Conduit Power effect.
+
+#### Enchantments
+- Implemented the following enchantments: Thorns, Sharpness, Knockback, Fire Aspect, Power, Punch, Flame, Infinity, Mending.
+
+#### Items
+- Added the following new items: `Scute`
+
+# 3.2.1
+- Fixed `VerifyLoginTask` completion bug when players get disconnected prior to the task completing.
+- Fixed client crash issue due to outdated runtime ID mappings.
+
+# 3.2.2
+- Updated NBT dependency to 0.2.1 to receive bug fixes (see https://github.com/pmmp/NBT/releases/tag/0.2.1).
+
+# 3.2.3
+- Errors thrown during level tick will now crash the server instead of spamming the console.
+- Fixed arrows despawning too soon after hitting the ground.
+- Fixed projectiles despawning before colliding if they were airborne for > 60 seconds.
+- Fixed crash related to Flame enchantment when the player shooting the arrow was on fire.
+
+# 3.2.4
+- Fixed levels unloaded during an earlier level's tick on the same tick causing a crash.
+- PermissibleBase->clearPermissions() now properly unsubscribes from all permissions.
+- Fixed incorrect break check for standing torch.
+- Fixed drops for brewing stand.
+- Fixed block picking brewing stand, bed, double slab, cake, farmland, and mob heads giving the wrong items.
+- Fixed blocks not placing correctly when clicking on redstone ore.
+- Fixed unknown PC items in tile inventories crashing the server - now they'll be quietly removed instead.
+- Fixed server freezing when eating chorus fruit from high altitude.
+- `readline` is now disabled by default on Windows and must be explicitly enabled with `--enable-readline` due to thread-safety issues.
+- Fixed server crash when trying to use non-implemented splash potions.
+- Removed incorrect maximum region file size cap which may have caused some worlds to be incorrectly detected as corrupted.
+
+# 3.2.5
+- `Player->sendForm()` now throws a proper exception when failing to JSON-encode `Form` objects given to it.
+- Fixed crash when handling later packets in a batch when an earlier packet triggered termination of the player's connection.
+- Fixed a race condition causing progress updates in `AsyncTasks` to be lost when published near completion.
+- Fixed bad decoding for some packets with unsupported structures.
+- Crash dumps no longer report 20 empty lines when an error occurs in `eval()`'d code.
+- `pocketmine/nbt` dependency updated to `0.2.2` to fix bugs (see NBT repo for changelog).
+
+# 3.2.6
+- Chunk ticking no longer occurs in chunks which have an adjacent unloaded chunks, fixing things like grass ticking triggering unintentional chunk loading.
+- Fixed some lighting propagation issues where step count is the same but light level is different.
+- Fixed full-chunk light repopulation producing broken lighting when the generator hasn't been registered on a worker.
+- Fixed a missing field in `MoveEntityDeltaPacket`.
+- Added client-sided rate limiting for crashdump reporting to mitigate involuntary DDoS of the crash archive.
+- Fixed a bug in `start.cmd` where quotes would appear around the "couldn't find installation" message.
+
+# 3.2.7
+- Added a network-layer check for item NBT size to avoid unexplained client-sided crashes due to length overflow.
+- Fixed some desync bugs with double chests when one half of a double chest is unloaded.
+- Anonymous class timings will now have a cleaned path for the identifier relative to the plugins directory.
+- Anonymous class timings now render correctly on timings.pmmp.io.
+- Fixed empty garbage subchunks not getting removed from long-life chunks.
+- `start.ps1`, `start.sh` and `start.cmd` no longer recognize source-code installations. Since source-code installations should only be used by developers who know what they are doing anyway, this was considered unwise to keep.
+- Fixed a bug/oversight in network chunk preparation that caused chunk prepare to be 4x slower than necessary.
+- `Chunk->fastSerialize()` now doesn't serialize useless data (data is omitted based on chunk flags). This significantly reduces the amount of useless data getting copied for generation, population and light calculation.
+- `TaskHandler->cancel()` was incorrectly marked as `@internal` in 2014. This has been fixed. Plugin developers should in fact prefer `TaskHandler->cancel()` since it does not require a task to have a circular dependency on its own executor.

+# 3.22.0
+- Added support for Minecraft: Bedrock Edition 1.17.10.
+- Removed compatibility with earlier versions.
+
+# 3.22.1
+- Added a giant yellow startup warning if using OPcache JIT on PHP 8.0. JIT is currently considered highly unstable and not recommended for production use.
+- When using a bad PHP binary, the bootstrap will now report the used `php.ini` path. This can be useful for debugging issues with extension loading when the wrong `php.ini` file is loaded for some reason.
+- Fixed `start.cmd` causing the wrong `php.ini` to be loaded on Windows when a global PHP installation is used.
+- A debug message is now logged containing expected vs. actual XUID of players when an XUID mismatch is detected.
+- Improved the documentation for `Player->getUniqueId()`.
+- Fixed a mistake in the documentation of `PlayerAuthInputFlags`.
+- Fixed incorrect encoding of `NpcDialoguePacket`.
+
+# 3.22.2
+- PHP 8.0 is now the primary supported version. PHP 7.4 is still supported for now, but it will be dropped in the coming weeks. It's recommended to start testing your servers on 8.0 now so you're ready.
+- Fixed items in the crafting grid getting deleted on server-side disconnect or session timeout.
+- A warning is now logged on startup if a debug build of PHP is used to run the server (because it has a significant performance impact).
+- GitHub Actions is now used to build new releases, instead of Jenkins. You can see build logs [here](https://github.com/pmmp/PocketMine-MP/actions/workflows/draft-release.yml).
+
+# 3.22.3
+- Fixed a bug in the release build of 3.22.2 which caused the crash archive to reject all crashdumps.
+- Fixed possible server crash during player spawning.
+
+# 3.22.4
+- Fixed a bug which broke the build of 3.22.3.
+
+# 3.22.5
+- Added a workaround for polyfilled solid-colour Persona skin replacements turning into a corrupted mess (caused by https://bugs.mojang.com/browse/MCPE-130275).

+**For Minecraft: Bedrock Edition 1.7.0**
+
+This is a cumulative minor release featuring performance improvements, memory usage improvements, some new minor gameplay features, some API deprecations and additions, and significant changes to error handling.
+
+### Note
+Plugins compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
+
+However, some API features have been deprecated in this version. Plugin developers do not need to do anything about these deprecations immediately, however they may raise harmless warnings if used.
+
+Features marked **`@deprecated`** are **recommended** not to be used, but will continue to work for any future 3.x.y versions. They will be removed in the next major release (4.0).
+
+# 3.4.0
+## Core changes
+### Performance & memory improvements
+- Entity `EXHAUSTION` attribute is no longer synced to the client, which reduces network traffic for survival players and reduces client-sided lag.
+- A redundant call was removed from an `Event` call hot path which improves event calling performance by ~15% per event handler executed.
+- Light updates are now batched together and executed on the end of each tick. The effects of this are noticeable when setting a large number of blocks in a close area - significant performance improvements should be noticeable for world editors (the ones that didn't disable light updates) and liquid flow is now significantly less expensive.
+- Internal enhancements have been made to subchunk light array interfacing to reduce branching and improve access performance.
+- Memory usage of most chunks has dropped by ~30-40% due to some improvements to internal storage of unlit subchunks. In real terms this translates to ~30% memory usage reduction for a freshly generated world.
+
+### Error handling
+The most notable core change in this release revolves around error handling. Internals have been cleaned up substantially to improve the server behaviour under occurrence of unexpected behaviour. The goal of this is to improve consistency and quality while reducing undefined runtime behaviour.
+The following changes have been made:
+- Throwing **unexpected** `Throwable`s in the following cases will now cause a server crash (except on network (this will be changed in the future)):
+  - Event handlers
+  - `Task->onRun()` on a scheduler
+  - `AsyncTask->onCompletion()`
+  - `Command->execute()` and `CommandExecutor->onCommand()`
+- Unexpected `Throwable`s thrown during packet handling will now cause the target player to be disconnected with an `Internal server error` message.
+
+### Other changes
+- Anti-flight has been removed, along with the `allow-flight` directive in `server.properties`.
+- Server language is now controlled by the `language` directive in `server.properties`.
+- Added `unban` and `unban-ip` as aliases of `pardon` and `pardon-ip` commands respectively.
+
+## API changes
+### Block
+- `BlockSpreadEvent` is now fired when lava or water tries to flow into a block.
+- `BlockFormEvent` is now fired when lava and water collide to form cobblestone, obsidian or stone.
+
+### Event
+- Added new method `Event->call()`. This should be used instead of `PluginManager->callEvent()` in plugins only supporting 3.4+.
+- `PluginManager->callEvent()` has been `@deprecated`.
+
+### Level
+- Attempting to unload a level during its tick will now throw an `InvalidStateException`.
+- Added the following new methods:
+  - `Level->broadcastPacketToViewers()`
+  - `Level->getViewersForPosition()`
+  - `Level->broadcastGlobalPacket()`
+  - `Level->getChunkAtPosition()`
+  - `Level->isInLoadedTerrain()`
+- `Level->addGlobalPacket()` has been `@deprecated`.
+- `LightUpdate` now allows calling `setAndUpdateLight()` for the same position multiple times (needed for light update batching).
+
+### Permission
+- `Permission::getByName()` now throws an exception on invalid values instead of silently returning `DEFAULT_FALSE`. This may cause new errors to appear if your plugins had broken permission defaults in `plugin.yml`.
+
+### Player
+- `addWindow()` now has stricter validity checks and will now throw exceptions in the following cases: No window IDs left to use, and when a forced window ID collides with an existing window.
+- The public `$speed` field has been removed (this was only used by anti-cheat which has now been removed).
+
+### Scheduler
+- `AsyncTask->setResult()` has had the `$serialize` parameter removed - now it will automatically serialize (or not) as appropriate.
+- Added a new `ClosureTask` which allows concisely scheduling closure execution on a `TaskScheduler`.
+- `TaskScheduler->__construct()` `$logger` parameter has been `@deprecated` and will be removed in a future major version.
+
+### Server
+- Added new method `Server->hasOfflinePlayerData(string $name) : bool`.
+- `Server->getAllowFlight()` has been `@deprecated`.
+
+### Utils
+- `Config->save()` will no longer catch unexpected exceptions thrown while encoding data.
+
+## Gameplay changes
+### Blocks
+- Rail connectivity has been implemented for normal, powered, detector and activator rails (but there are currently no minecarts).
+
+# 3.4.1
+- Updated crashdump format to be compatible with newest CA. This version or newer is required if you want to be able to submit crashdumps to crash.pmmp.io.
+
+# 3.4.2
+- `DataPacket` errors when writing to undefined fields are now more clear.
+- Fixed trees being able to overwrite the log parts of other trees.
+- Fixed `Player->sendForm()` not working during `PlayerJoinEvent`.
+- `Entity->setScale()` now explicitly requires a scale larger than 0.
+- Adding invisible `FloatingTextParticle` to a level no longer causes an error.
+
+# 3.4.3
+- Fixed burning TNT setting hurt entities on fire when exploding.
+- `~` relative coordinates now work in the `/particle` command.
+- Various boring fixes to error stack trace reporting.
+- `Level->setChunk()` no longer deletes tiles and entities when replacing a chunk with itself.
+- Fixed a generator race condition causing rare appearances of half-trees on the client in freshly generated terrain.
+- `Attribute->resetToDefault()` now fits the default per the min/max bounds, fixing crashes when the bounds are changed to exclude the default.
+- Fixed a crash with LevelDB worlds when the `TAG_2D_MAPS` tag is missing.
+- Fixed `Utils::getCoreCount()` crashing on some Debian variants.

+- Ender chests now make the correct sounds when opening and closing.
+- Fixed Sign errors when a buggy or malicious client sent broken NBT with the wrong tags or wrong number of lines.
+- Resource packs with comments in the manifest will now load correctly. (MOJANG!!!)
+- Placement of unknown blocks is now disallowed. This solves a range of problems with invalid blocks in the world, such as #2260 .
+- Errors thrown during `PlayerQuitEvent` or other `Player->close()` errors will now crash the server instead of causing cryptic bugs later on.
+- Fixed large chunks (>= 1044476 bytes) becoming corrupted when saved in Region-based worlds - now an exception is thrown instead.
+- Reduced the range of exceptions caught during chunk loading. Now, only chunk corruption errors are caught, and anything else will produce a crash.
+- Removed catch-all block on chunk saving. Unexpected errors thrown during chunk save will now create a crash.
+- Fixed some asserts in packet decode methods.
+- `Attribute` now throws exceptions with more informative messages on errors.
+- Properly handled some remaining `Uninitialized string offset` bugs when decoding packets.
+- Fixed chunk updates taking several seconds to show up on the client. This bug was most apparent during generation and some world editing tools using asynchronous tasks.
+- Fixed CPU waste ordering chunks for non-moving players.
+
+# 3.5.4
+### Fixes
+- Fixed server crash when a block update occurs on a torch with corrupted metadata.
+- Added a hack to mitigate client-side right-click spam bug. This mostly eliminates spam of `PlayerInteractEvent` on right-click.
+- Players will no longer see commands they don't have permission to use in client-sided hints when typing a `/` in the chat window.
+- `Event->isCancelled()` and `Event->setCancelled()` now throw more informative errors.
+- Errors thrown during a network interface processing will now _actually_ crash the server.
+
+### API changes
+- Deprecated `NetworkInterfaceCrashEvent`. Nobody should have been using this anyway.
+- Deprecated `Network->processInterface()`

+
+# 3.5.5
+- Mobs no longer spawn with their heads facing a different direction to their bodies.
+- Added a console message when the crash strangler sleeps to stop crash spam.
+- Fixed crash in `/title` command `times` subcommand when not enough arguments were passed.
+- AsyncWorkers will now not be shut down on GC unless they have not been used for the last 5 minutes. This reduces lag spikes on garbage collection.
+- Fixed some unhandled error cases in `AddEntityPacket` encoding.
+- Fixed `LogicException` descendents being thrown from some packet decoding methods when encountering bad userdata.
+- Player network inventory transaction processing now catches more specific errors.
+- Fixed missing decode for `TakeItemEntityPacket`.

+- Global functions and constants are now imported to improve performance.
+- Fixed a typo in `pocketmine.command.op.take` description.
+- Ice no longer creates water when a creative player breaks it.

+- Added a hack to disable pre-spawn client-sided movement.
+- Assertions enabled warning now always shows when `zend.assertions` is not `-1`. The config option to disable this warning has been removed.
+- `/status`,`/dumpmemory` and `/gc` are now enabled by default. The `debug.commands` config option has been removed.
+- Crash dumps are now more thorough at catching plugin-related crashes.
+
+# 3.5.6
+- Fixed `#`-commenting properties in `.properties` files not working.
+- `pocketmine.yml` now permits writing `worldname:` with no generation settings in the `worlds` section to force a world to be loaded.
+- Fixed Bow force being too low - now it's consistent with Minecraft Java (but not with Bedrock due to a vanilla bug).
+- Fixed `recursion detected` bug when encoding crashdumps in some cases.
+- Items with too-large NBT tags on network will now have their tags ignored when sending over network, instead of crashing the server. This is a workaround for a protocol bug which will be addressed in a future Minecraft release.
+- `/enchant` no longer crashes the server when out-of-bounds enchantment levels are used.
+- Fixed some crashes loading Region-based worlds when encountering unexpected EOF.
+- `Entity->fireTicks` is now protected (but accessible by magic method for BC purposes) and will now throw an exception when written to if the value is > 32767 or < 0.
+- Fixed Signs asserting on corrupted world data with more than 4 lines of text per sign.
+
+# 3.5.7
+- Fixed several bugs in RCON packet receive that would allow an attacker to block or crash the RCON thread, denying service to other legitimate RCON clients.
+- Fixed RCON connections not working (timing out with no response) on some platforms.
+- Logins are now permitted to have up to 60 seconds clock drift on the `nbf` and `exp` timestamps in the login JWT.

+- Startup time no longer includes the time spent in the setup wizard.
+- `TextFormat::clean()` is now UTF-8 aware, and will scrub any invalid UTF-8 characters from the given string.
+- Fixed `TextFormat::clean()` not fully removing ANSI escape codes in some cases.
+- Fixed Korean command arguments failing to parse.
+- `Sign->setText()` and `Sign->setLine()` now enforce that the given text must be UTF-8 text, or an exception will be thrown.
+- Sign text is now processed by `mb_scrub()` immediately after loading to remove invalid UTF-8 characters that could crash the client.
+- `Human->exhaust()` no longer underflows when the hunger attribute has a fractional value.
+
+# 3.5.13

+
+# 3.6.2
+- Fixed client-sided crash when upper-case letters appear in command names.
+- Fixed crash when too-large values are given to `/effect` for duration.
+- `/op` and other commands no longer crash when an invalid player name is given.
+- Startup time no longer includes the time spent in the setup wizard.
+- `TextFormat::clean()` is now UTF-8 aware, and will scrub any invalid UTF-8 characters from the given string.
+- Fixed `TextFormat::clean()` not fully removing ANSI escape codes in some cases.
+- Fixed Korean command arguments failing to parse.
+- `Sign->setText()` and `Sign->setLine()` now enforce that the given text must be UTF-8 text, or an exception will be thrown.
+- Sign text is now processed by `mb_scrub()` immediately after loading to remove invalid UTF-8 characters that could crash the client.
+- `Human->exhaust()` no longer underflows when the hunger attribute has a fractional value.
+
+# 3.6.3

+# 3.6.5
+- Fixed stdout silence on crash if a crash occurs when PHP output buffering is enabled.
+- Fixed `RegionLoader` considering a range of invalid chunk coordinates as valid.
+- Fixed `RegionLoader` causing region header corruption when an oversized chunk was discovered. This was causing entire regions to be discarded next time they were freshly loaded.
+- Fixed performance issue loading old LevelDB worlds (from before MCPE 1.0) due to unmodified chunks being converted every time they were loaded.
+- Added new debug messages when a world takes too long (longer than 50ms) to complete a tick.
+- Debug messages are now logged when autosave kicks in (with time measurements), which helps debugging unexplained lag spikes.
+- Level "auto tick rate" anti-feature and its associated `pocketmine.yml` settings have been removed (see #2665). The settings will persist in old configurations, but will be ignored by this version and future versions.
+- The `/save-all` command now outputs custom (non-vanilla) messages informing the user how long it took to complete autosaving.

+**For Minecraft: Bedrock Edition 1.12.0**
+
+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.
+
+**WARNING: If your plugin uses the protocol, you're not shielded by API change constraints.** You should consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you do.
+
+# 3.9.0
+- Added support for Minecraft: Bedrock Edition 1.12.0
+- Removed compatibility with 1.11.0
+
+## Protocol
+- The following classes in the `\pocketmine\network\mcpe\protocol` namespace have been renamed:
+  - `AddEntityPacket` -> `AddActorPacket`
+  - `AddItemEntityPacket` -> `AddItemActorPacket`
+  - `AvailableEntityIdentifiersPacket` -> `AvailableActorIdentifiersPacket`
+  - `BlockEntityDataPacket` -> `BlockActorDataPacket`
+  - `EntityEventPacket` -> `ActorEventPacket`
+  - `EntityFallPacket` -> `ActorFallPacket`
+  - `EntityPickRequestPacket` -> `ActorPickRequestPacket`
+  - `MoveEntityAbsolutePacket` -> `MoveActorAbsolutePacket`
+  - `MoveEntityDeltaPacket` -> `MoveActorDeltaPacket`
+  - `RemoveEntityPacket` -> `RemoveActorPacket`
+  - `SetEntityDataPacket` -> `SetActorDataPacket`
+  - `SetEntityLinkPacket` -> `SetActorLinkPacket`
+  - `SetEntityMotionPacket` -> `SetActorMotionPacket`
+  - `TakeItemEntityPacket` -> `TakeItemActorPacket`
+- The following classes in the `\pocketmine\network\mcpe\protocol` namespace have been removed:
+  - `FullChunkDataPacket`
+- The following classes in the `\pocketmine\network\mcpe\protocol` namespace have been added:
+  - `AddEntityPacket` (not to be confused with the old one)
+  - `ClientCacheBlobStatusPacket`
+  - `ClientCacheMissResponsePacket`
+  - `ClientCacheStatusPacket`
+  - `LevelChunkPacket`
+  - `RemoveEntityPacket` (not to be confused with the old one)
+  - `StructureTemplateDataExportRequestPacket`
+  - `StructureTemplateDataExportResponsePacket`
+
+# 3.9.1
+- Fixed resource packs not working on 1.12 clients.
+- Fixed some particles displaying incorrectly (some still don't render at all).
+- Fixed `Entity->setFireTicks()` with a value of `0` setting the on-fire flag.
+- Silenced a debug message which appeared every time a player right-clicked a block.
+- Updated constants for `LevelSoundEventPacket`.
+
+# 3.9.2
+- Logger warnings for illegal player movements have been lowered to debug.
+- TNT explosions now start from the center instead of the base. This fixes unexpected results when TNT is lit on top of obsidian.
+- Fixed the `loadbefore` directive in `plugin.yml` sometimes being ignored.
+- Fixed `Item->setCustomName()` with an empty string leaving behind an empty tag.
+- Fixed incorrect positioning of bucket empty sound.
+- Fixed some incorrect tag parsing in `/give` involving quoted numbers.
+
+# 3.9.3
+- Fixed a memory leak on async task removal in error conditions.
+- Fixed scheduled block updates (for example liquid) triggering chunk reloading. This could cause a significant performance issue in some conditions.
+- Fixed some minor cosmetic issues in documentation.
+
+# 3.9.4
+- Fixed a memory leak when scheduled updates were pending on a chunk being unloaded.
+- Fixed plugin detection in crashdumps. Previously `src/pocketmine` anywhere in the path would cause the error to be considered a core crash, regardless of the preceding path.
+- Fixed entity metadata types for 1.12. The SLOT type was removed and a COMPOUND_TAG type added. This change involves changes to internal API which may break plugins. **See the warning at the top of this changelog about API versioning.**
+- Fixed random and base populator amounts of trees and tallgrass never being initialized. This bug had no obvious effect, but may have become a problem in future PHP versions.
+- The following internal methods have been marked as `@deprecated` and documentation warnings added:
+  - `Entity->getBlocksAround()`
+  - `Entity->despawnFrom()`
+  - `Entity->despawnFromAll()`
+- Fixed plugin `softdepend` not influencing load order when a soft-depended plugin had an unresolved soft dependency of its own.
+- Fixed endless falling of sand on top of fences.
+
+# 3.9.5
+- Fixed some issues with multiple consecutive commas inside quotes in form responses.
+- Fixed server crash when the manifest json does not contain a json object in a resource pack.
+- Ender pearls no longer collide with blocks that do not have any collision boxes.
+
+# 3.9.6
+- Updated Composer dependencies to their latest versions.
+- Prevent clients repeating the resource pack sequence. This fixes error spam with bugged 1.12 clients.
+- `Internet::simpleCurl()` now includes the PocketMine-MP version in the user-agent string.
+- Spawn protection is now disabled by default in the setup wizard.
+- Default difficulty is now NORMAL(2) instead of EASY(1).
+- Fixed crashing on corrupted world manifest and unsupported world formats.
+- Fixed `/transferserver` being usable without appropriate permissions.
+- `RegionLoader->removeChunk()` now writes the region header as appropriate.
+- Fixed performance issue when loading large regions (bug in header validation).
+- Fixed skin geometry being removed when the JSON contained comments.
+- Added new constants to `EventPacket`.
+- Added encode/decode for `StructureTemplateDataExportRequestPacket` and `StructureTemplateDataExportResponsePacket`.
+- Fixed broken type asserts in `LevelChunkPacket::withCache()` and `ClientCacheMissResponsePacket::create()`.
+- `types\CommandParameter` field `byte1` has been renamed to `flags`.
+- Cleaned up public interface of `AvailableCommandsPacket`, removing fields which exposed details of the encoding scheme.
+- Improved documentation for the following API methods:
+  - `pocketmine\item\Item`:
+    - `addCreativeItem()`
+    - `removeCreativeItem()`
+    - `clearCreativeItems()`
+  - `pocketmine\level\Explosion`:
+    - `explodeA()`
+    - `explodeB()`
+- Fixed various cosmetic documentation inconsistencies in the core and dependencies.
+
+# 3.9.7
+- Fixed a crash that could occur during timezone detection.
+- Squid no longer spin around constantly in enclosed spaces. Their performance impact is reduced.
+- Cleaned up the bootstrap file.
+
+# 3.9.8
+- Added [PHPStan](https://github.com/phpstan/phpstan) configuration. PHPStan is now used on CI for automated QA, which should improve stability and quality going forward.
+- The following constants are now autoloaded when loading the Composer autoloader:
+  - `pocketmine\NAME`
+  - `pocketmine\BASE_VERSION`
+  - `pocketmine\IS_DEVELOPMENT_BUILD`
+  - `pocketmine\BUILD_NUMBER`
+  - `INT32_MIN`
+  - `INT32_MAX`
+  - `INT32_MASK`
+- Fixed memory leaks and crashes caused by plugin use of `Player->showPlayer()` and `Entity->spawnTo()`.
+- Fixed crashes that could occur when tile classes were overridden with classes incompatible with the originals.
+- Fixed improper handling of non-Compound root NBT tags on network itemstack decoding.
+- Fixed paintings dropping multiple items when destroyed by block updates.
+- Fixed `var_dump()` not showing private and protected properties of `DataPacket` subclasses.
+- Fixed overloads with zero arguments being missing when decoding `AvailableCommandsPacket`.
+- `CraftingDataPacket` now retains the `cleanRecipes` field when decoding.
+- Fixed `Block->getMetadata()` returning null (non-iterable).
+- `PlayerChatEvent` documentation has been updated to specify that `CommandSender` recipients are accepted. This behaviour was already present in previous versions, but incorrectly documented.
+- Fixed various issues with PHPDoc comments reported by PHPStan.
+- Fixed various minor code nits reported by PHPStan.
