 ### 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.
+- **All code must be licensed under the [LGPLv3 license](LICENSE)** as per PocketMine-MP's own license, or a compatible 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 ONE thing**

+- **Test code changes, and tell us what tests have been done.**
+  - 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 could lead to your PR being declined.
+- **Code, comments and documentation must be written in American English.** English is the shared languages of all current maintainers.

+  - You can also use [`php-cs-fixer`](https://github.com/FriendsOfPHP/PHP-CS-Fixer) to format your code.
+- **Use `final` and `private` wherever possible**.
+  - Changing from `private` to `protected` or `final` to non-`final` doesn't break backwards compatibility, but the opposite does.
+  - `private` and `final` also enable certain performance optimizations which are otherwise not possible.
+  - `private` members can be freely changed, added and removed in the future, so it's ideal for internal functions. Abusing `protected` makes internal improvements inconvenient.
+  - "Let's leave it protected/public in case someone needs it for ... idk what" is **not a valid reason to expose things**. If there isn't a clear reason for something to be accessible from the outside, don't expose it.
+  - **This is a lesson learned through years of experience.** You may not like it, but it's for the best.
+- **Immutable things are almost always preferred.**
+  - Do not add unnecessary setters or public writable properties to classes. As above, "Let's leave it in case someone needs it" is **not a valid reason to expose things**.
+  - Mutable classes and properties are unpredictable, since code has no way to know if the object it's working with might be randomly modified by another part of the code. This makes it harder to maintain code and debug issues.
+  - Most classes exist only to hold some data. These are called "data transfer objects" (DTOs). These types of classes should pretty much always be immutable.
+  - Make use of `final`, `private` and `readonly` modifiers.
 
 ### Recommendations
-
+- **Be patient.** Reviewing pull requests takes a lot of time and energy, and maintainers are often unavailable or busy. Your PR might not receive attention for a while.
+  - Remember, PRs with small diffs are much easier to review. Small PRs are generally reviewed and merged much faster than large ones.
+- **Start small.** Try fixing minor bugs or doing something isolated (e.g. adding a new block or item) before attempting larger changes.
+  - This helps you get familiar with the codebase, the contribution process, and the expectations of maintainers.
+  - Check out the [issues page]() for something that you could tackle without too much effort.
+- **Do not copy-paste other people's code**. Many PRs involve discussion about the changes, and changes are often requested by reviewers. If you don't understand the code you're copy-pasting, your PR is likely to fail.
 - **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.
+- **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.
 - **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.
+- **Make your PR diff as small as possible.** Smaller PRs are **much more likely** to be accepted, as they are easier to review.
+  - Avoid moving code around in files if possible.
+  - Don't make random CS changes. This makes the diff noisier and harder to review.
 - **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.
-- **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.
+- **Split unrelated changes into multiple commits.**
+  - An atomic style for commits is preferred - this means that changes included in a commit should be part of a single distinct change set.
+  - If you need to use "and" or "multiple changes" in your commit message, the commit probably needs to be split up. There are exceptions, but this is a good rule of thumb.
+  - See [this link](https://www.freshconsulting.com/atomic-commits/) for more information on atomic commits.
+  - See the [documentation on `git add -i` or `git add -p`](https://git-scm.com/docs/git-add) for information on how to split up local changes for committing.

 </p>
 
-## Getting started
+## What is this?
+PocketMine-MP is a highly customisable server software for Minecraft: Bedrock Edition, built from scratch in PHP, with over 10 years of history.
+
+If you're looking to create a Minecraft: Bedrock server with **custom functionality**, look no further.
+
+- 🧩 **Powerful plugin API** - extend and customise gameplay as you see fit
+- 🗺️ **Rich ecosystem** and **large developer community** - find plugins easily and learn to develop your own
+- 🌐 **Multi-world support** - offer a more varied game experience to players without transferring them to other server nodes
+- 🏎️ **Performance** - get 100+ players onto one server (depending on hardware and plugins)
+- ⤴️ **Continuously updated** - new Minecraft versions are usually supported within days
+
+## :x: PocketMine-MP is NOT a vanilla Minecraft server software.
+**It is poorly suited to hosting vanilla survival servers.**
+It doesn't have many features from the vanilla game, such as vanilla world generation, redstone, mob AI, and various other things.
+
+If you just want to play **vanilla survival multiplayer**, consider using the [official Minecraft: Bedrock server software](https://minecraft.net/download/server/bedrock) instead of PocketMine-MP.
+
+If that's not an option for you, you may be able to add some of PocketMine-MP's missing features using plugins from [Poggit](https://poggit.pmmp.io/plugins), or write plugins to implement them yourself.

+# 4.22.0
+Released 7th June 2023.
+
+**For Minecraft: Bedrock Edition 1.20.0**
+
+This is a support release for Minecraft: Bedrock Edition 1.20.0.
+
+**Plugin compatibility:** Plugins for previous 4.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## Interim releases
+If you're upgrading from 4.20.x directly to 4.22.x, please also read the following changelogs, as the interim releases contain important changes:
+- [4.21.0](https://github.com/pmmp/PocketMine-MP/blob/4.22.0/changelogs/4.21.md#4210) - PHP 8.1 minimum version, minor performance improvements
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.20.0.
+- Removed support for older versions.
+
+## Fixes
+- Removed deprecated `ReflectionProperty::setAccessible()` calls.
+- Fixed jukebox music not stopping when destroyed by an explosion.
+
+# 4.22.1
+Released 9th June 2023.
+
+## Fixes
+- Replaced workaround for an old teleporting client bug:
+  - This workaround broke due to an additional client bug introduced by 1.20, causing players to become frozen to observers when teleported.
+  - The original client bug has still not been fixed, meaning a new workaround was needed, but no perfect solution could be found.
+  - The new workaround involves broadcasting teleport movements as regular movements, which causes unwanted interpolation between the old and new positions, but otherwise works correctly. This solution is not ideal, but it is the best we can do for now.
+  - See issues [#4394](https://github.com/pmmp/PocketMine-MP/issues/4394) and [#5810](https://github.com/pmmp/PocketMine-MP/issues/5810) for more details.
+
+# 4.22.2
+Released 1st July 2023.
+
+## Changes
+- Added obsoletion warnings to the server log at the end of the startup sequence.
+
+## Fixes
+- Fixed players being disconnected en masse with "Not authenticated" messages.
+  - This occurred due to a check intended to disable the old authentication key after July 1st.
+  - We expected that the new key would have been deployed by Mojang by now, but it seems like that has not yet happened.
+  - Due to the lack of a hard date for the key changeover, we guessed that July 1st would be a safe bet, but this appears to have backfired.
+  - This version will accept both old and new keys indefinitely.
+  - A security release will be published to remove the old key after the transition occurs.
+
+# 4.22.3
+Released 11th July 2023.
+
+## Fixes
+- Fixed mishandling of NBT leading to a server crash when editing signs.
+- Fixed an edge case crash that could occur in `AsyncTask->__destruct()` when thread-local storage referenced other `AsyncTask` objects.
+
+## Internals
+- Added a concurrency lock to prevent the `update-updater-api` GitHub Action from running for multiple releases at the same time (which would have caused one of them to fail due to git conflicts).

+# 5.0.0
+Released 1st June 2023.
+
+**For Minecraft: Bedrock Edition 1.19.80**
+
+5.0.0 is a major feature update to PocketMine-MP, including support for Bedrock worlds from 1.13 onwards, a large array of new blocks and items, and various changes to the plugin API.
+
+It is **not** compatible with plugins written for 4.x.y, and plugins may require code changes to work with it.
+
+**As this changelog is quite large, its accuracy and completeness cannot be guaranteed.**
+Make sure you're looking at the [latest revision](https://github.com/pmmp/PocketMine-MP/blob/stable/changelogs/5.0.md), as it may be amended after release.
+
+## Core
+- Worlds are now saved according to the Bedrock 1.19.80 format.
+- Worlds generated by Bedrock from 1.13.0 and up are now supported (previously, only worlds up to 1.12 were supported).
+- `/particle` now accepts strings for particle data instead of integers.
+- `/particle` no longer accepts integers for block or item IDs.
+- The usage of `blockcrack`, `iconcrack` and `blockdust` particle types in `/particle` now follows the same pattern as
+  other particle types, with the data for each being passed in the `data` parameter instead of being baked into the
+  particle name.
+- Commands are now enabled by default in worlds exported from PocketMine-MP to Bedrock.
+
+## Build system
+- `build/generate-block-serializer-consts.php` has been added to generate `BlockTypeNames`, `BlockStateNames` and `BlockStateStringValues` in the `pocketmine\data\bedrock\block` package.
+- `build/generate-item-type-names.php` has been added to generate `ItemTypeNames` in the `pocketmine\data\bedrock\item` package.
+- `build/generate-runtime-enum-serializers.php` has been added to generate `RuntimeEnumSerializer`, `RuntimeEnumSerializerTrait`, and `RuntimeEnumSizeCalculatorTrait` in `pocketmine\data\runtime` package.
+
+## Localization
+- Localized disconnect messages are now used in the following cases:
+  - Server full
+  - Player not on the server whitelist
+  - Player on the server ban list
+  - Invalid skin
+  - Invalid username
+  - Kicked using `/kick`
+  - Banned using `/ban`
+  - Failure to find a safe spawn position
+- Session open, session close and session player name discovery messages are now localized.
+- All permissions now have localized descriptions. These are not currently used by PocketMine-MP, but may be useful for plugins.
+
+## Performance
+- Improved performance of dropping block inventory contents when the block is destroyed.
+- Improved light propagation performance by 10-15%.
+- [`ext-pmmpthread` version 6.0.0](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.0.0) is now used, featuring significant performance improvements for thread-safe objects and various threading use-cases.
+
+## Tools
+- The following tool scripts have been added:
+  - `generate-block-palette-spec.php` - generates a JSON file with a readable overview of blocks, their state
+    properties, and their possible values
+  - `generate-blockstate-upgrade-schema.php` - generates JSON blockstate upgrade schemas like those found
+    in [BedrockBlockUpgradeSchema](https://github.com/pmmp/BedrockBlockUpgradeSchema)
+  - `generate-item-upgrade-schema.php` - generates JSON item ID/meta upgrade schemas like those found
+    in [BedrockItemUpgradeSchema](https://github.com/pmmp/BedrockItemUpgradeSchema)
+  - `generate-bedrock-data-from-packets.php` - generates various files for [BedrockData](https://github.com/pmmp/BedrockData)
+    - This script accepts a txt file containing base64-encoded packet dumps.
+    - This script has been in use for several years, but has only now been open-sourced.
+    - It's used to generate data such as crafting recipes, creative inventory data, and various other blobs of data needed to support the current version of Minecraft: Bedrock Edition.
+
+## Gameplay

+
+### `pocketmine\block`
+#### Highlights
+- Blocks no longer use internal Minecraft IDs and metadata to identify themselves. All APIs associated with legacy IDs
+  and meta have been removed.
+- A new set of runtime IDs generated from `VanillaBlocks` is used to identify block types. These IDs are defined
+  in `BlockTypeIds`.
+  - These new IDs are used for runtime representation of blocks on chunks, and for type comparison purposes.
+  - Block type IDs are used at **runtime only**. **Do not store them in configs or databases**, as they are subject to
+    change without warning.
+  - Block type IDs are **specific to PocketMine-MP** and have no relation to the IDs used by Minecraft.
+  - Block type IDs cannot be negative
+  - Block type IDs must not be reused, even if overriding an already defined block
+- Block state properties (e.g. facing, colour, etc.) are now represented by PM-specific state data instead of legacy
+  metadata. The state data consists of:
+  - Block-item state properties - retained by items when the block is broken (colour, wet/dry, coral type, etc.) - handled by `Block->describeBlockItemState()`
+  - Block-only state data - discarded when the block is broken (facing direction, lit/unlit, powered/unpowered, etc.) - handled by `Block->describeBlockOnlyState()`
+- Chunks now store dynamic state ID derived from the runtime type ID and runtime (PocketMine-MP defined) state data.
+- Introduced "type tags" concept, which allows marking certain blocks as having certain behaviours.
+  - The idea for this system was borrowed from the Minecraft Java tags system.
+  - It's still in very early concept stage, but is currently used for deciding which types of blocks plants can be placed on without needing to enumerate every single ID in every class, eliminating a bunch of boilerplate code and improving consistency.
+- All `Block` descendents now accept `BlockTypeInfo` in the constructor, instead of `BlockBreakInfo`. This allows for future additions without needing to change dozens of overridden constructors.
+- `&$returnedItems` reference parameter is now used in some places such as `Block->onInteract()` to enable actions to return items to players without caring about whether they are in creative or anything else.
+  - This eliminates boilerplate code of deciding whether to set the player's held item or not, as well as automatically dropping any overflow items that don't fit into the inventory.
+  - This is currently used when filling/emptying cauldrons using buckets or glass bottles.
+- Dependency between `RuntimeBlockStateRegistry` (previously `BlockFactory`) and `VanillaBlocks` has been inverted.
+  - Now, blocks types are defined in `VanillaBlocks`
+  - `RuntimeBlockStateRegistry` automatically registers states for blocks defined in `VanillaBlocks`.
+  - Manual registration in `RuntimeBlockStateRegistry` is still required for custom blocks (see section below about registering new blocks).
+- `RuntimeBlockStateRegistry` now has only one purpose - to map internal blockstate IDs to `Block` objects when reading blocks from chunks. It should not be used by plugins unless registering new blocks.
+  - To get a block at runtime, e.g. stone, use `VanillaBlocks::STONE()`
+  - To load a block from **old** config or database data:
+    1. Use `GlobalBlockStateHandlers::getUpgrader()->upgradeIntIdMeta()` to convert it to modern data
+    2. Pass the data to `GlobalBlockStateHandlers::getDeserializer()` to get a blockstate ID
+    3. Pass the blockstate ID to `RuntimeBlockStateRegistry::fromStateId()` to get a `Block` instance
+  - Prefer using `StringToItemParser` wherever possible for configs and databases (see `lookupAliases()` and `lookupBlockAliases()`).
+
+#### Registering new blocks
+##### In a plugin
+To add a vanilla block in a plugin which isn't yet supported by PocketMine-MP, do the following:
+
+1. Get a new type ID using `BlockTypeIds::newId()` - _you'll want to keep this in a property somewhere if you want to
+   compare using `getTypeId()` later_
+2. Set up the block type somewhere - _this can be anywhere you like, e.g. a plugin main class property, but using
+   a `RegistryTrait` class is recommended - you'll need this later to create new instances of the block_
+3. Register the block in `RuntimeBlockStateRegistry` - _this informs the server of all the block's possible states so
+   that it can be read from chunks at runtime_
+4. Register a deserializer for the block's Minecraft ID in `BlockStateToObjectDeserializer` - _needed for the block to
+   be recognized when loaded from disk_
+5. Register a serializer for the block in `BlockObjectToStateSerializer` - _needed for the block to be saved to disk,
+   and to be sent over the network_
+6. Optionally, register a string alias for the block in `StringToItemParser` - _so that it can be given via `/give`_
+
+To see a demo of how to do this in a plugin, see [this example plugin](https://github.com/pmmp/RegisterBlocksDemoPM5).
+
+Registering custom blocks follows a similar process, but requires additional steps to modify `BlockStateDictionary`
+which won't be covered here.
+Since this is not currently officially supported by PocketMine-MP, this won't be covered here.
+
+This is admittedly rather more of a hassle than in PM4, but this system offers significantly more flexibility than the
+old system.
+
+##### As a PocketMine-MP core contribution
+To register a new vanilla block into the core, the process is slightly different:
+
+1. Instead of using `BlockTypeIds::newId()`, add a new constant for the block to `BlockTypeIds`
+2. Register the new block in `VanillaBlocks` - `RuntimeBlockStateRegistry` will automagically take notice of all blocks
+   defined in `VanillaBlocks`
+3. Follow steps 4 onwards above

+
+### `pocketmine\command`
+- Command permissions are now always checked by the server when running a command.
+  - This only affects commands implemented by extending `Command`. Plugins using `PluginBase->onCommand()` are not affected by this change, since they already had permissions checked by the server anyway.
+  - Previously, direct inheritors of `Command` were responsible for checking permissions, which required developers to duplicate the same code in every command, and opened lots of potential for security vulnerabilities.
+  - If you want to do something on permission denied (e.g. sending a special message, or audit logging), you can do so by overriding `Command->testPermission()`, instead of baking the code directly into `Command->execute()`.
+  - If you don't want to use permissions at all, just create a permission with a default of `true` (or belonging to `pocketmine.group.user`) and assign that.
+- `SimpleCommandMap` now requires all commands to have a permission set when registered.
+  - If you actually want to allow everyone to use your command (not advised), you can add a new permission to the `pocketmine.group.user` group, or use `default: true` for `plugin.yml` permissions.
+- The following API methods have changed behaviour:
+  - `Command->testPermissionSilent()` now returns `false` if there are no permissions associated with the command. This is to prevent commands with no permissions being usable by everyone, which has previously been a source of security issues.
+- The following API methods have been added:
+  - `public Command->getPermissions() : list<string>` - returns a list of permissions which grant usage access to this command. A user with one or more of these permissions will be able to invoke the command's `execute()` method
+  - `public Command->setPermissions(list<string> $permissions) : void` - sets the permissions which grant usage access to this command. This should be used instead of `setPermission()` with `;` separators (which is now deprecated)
+

+- The following classes have inheritance changes:
+  - `PlayerPreLoginEvent` no longer implements `Cancellable`. This caused unexpected behaviour for most plugin devs due to default-ignoring cancelled events, forcing people to usually have to use `@handleCancelled` to handle the event when they wanted to use it.

+
+### `pocketmine\item`
+#### Highlights
+- `ItemFactory` has been removed. Vanilla item registration is now done via `VanillaItems`.
+  - To get an item at runtime, e.g. iron ingot, use `VanillaItems::IRON_INGOT()`
+  - To get a block as an item, e.g. stone, use `VanillaBlocks::STONE()->asItem()`
+  - To load an item from legacy ID and meta:
+    1. Use `GlobalItemDataHandlers::getUpgrader()->upgradeItemTypeDataInt()` to convert the legacy ID and meta to `SavedItemStackData`
+    2. Pass the itemstack data to `GlobalItemDataHandlers::getDeserializer()` to get an `Item` instance
+- Items no longer use internal Minecraft string IDs and metadata to identify themselves. All APIs associated with legacy
+  IDs and/or meta have been removed.
+- A new set of runtime item IDs generated from `VanillaItems` is now used to identify item types. These IDs are defined
+  in `ItemTypeIds`.
+  - These new IDs are primarily intended for type comparison purposes.
+  - Item type IDs are used at **runtime only**. They should **NOT** be stored in configs or databases, as they are not
+    guaranteed to remain the same between versions.
+- In some cases, items may have additional "type data" which provides extra type information about an item. This
+  replaces item metadata in some cases.
+  - Type data may be used to store dynamic type information such as dye colour, potion type, etc.
+  - Items must have the same type ID **and** type data in order to be stackable.
+- Blocks, when represented as items:
+  - retain their block type data, but not state data (for example, different colours of concrete don't stack, but things
+    like facing don't affect stackability)
+  - use the negative of their block type ID (e.g. a block with type ID `1` will have an item type ID of `-1`).
+- Durable items (e.g. tools, armour) now use NBT `Damage` tag to store durability (like Minecraft 1.13+), instead of
+  legacy meta values.
+- `&$returnedItems` reference parameter is now used in some places (e.g. `onInteractBlock()`) to enable actions to return items to players without caring about whether they are in creative or anything else.
+  - This eliminates boilerplate code of deciding whether to set the player's held item or not, as well as automatically dropping any overflow items that don't fit into the inventory.
+  - This is used for things like filling/emptying buckets and bottles, and equipping armor.
+- Blocks which previously had separate items, such as mob heads and beds, no longer do. Their item form can be acquired using `Block->asItem()` in the same way as every other block. This is facilitated by the new serializer system.
+
+#### Implementing new items
+##### In a plugin
+This follows a similar process to registering blocks.
+
+1. Get a new type ID using `ItemTypeIds::newId()` - _you'll want to keep this in a property somewhere if you want to
+   compare using `getTypeId()` later_
+2. Set up the item type somewhere - _this can be anywhere you like, e.g. a plugin main class property, but using
+   a `RegistryTrait` class is recommended - you'll need this later to create new instances of the item_
+3. Register a deserializer in `ItemDeserializer` - _needed for the item to be recognized when loaded from disk_
+4. Register a serializer in `ItemSerializer` - _needed for the item to be saved to disk, and to be sent over the
+   network_
+5. Optionally, register a string alias for the item in `StringToItemParser` - _so that it can be given via `/give`_
+
+To see a demo of how to do this in a plugin, see [this example plugin](https://github.com/pmmp/RegisterBlocksDemoPM5).
+
+Again, it's acknowledged this is rather more cumbersome than it should be, but this is an ongoing process.
+
+##### As a PocketMine-MP core contribution
+
+To register a new vanilla item into the core, the process is slightly different:
+
+1. Instead of using `ItemTypeIds::newId()`, add a new constant for the block to `ItemTypeIds`
+2. Register the new item in `VanillaItems`
+3. Follow steps 3 onwards from the plugin instructions above
+
+#### Change list
+- `Item` is no longer `json_encode()`-able.
+  - The original purpose of this was to allow items to be serialized to JSON for crafting data generated from `CraftingDataPacket`. Due to changes in the generation methodology, bypassing `Item`s entirely, this is no longer necessary.
+  - In addition, `jsonSerialize()` required the item to know about the method by which it will be serialized (since there is no way to inject context), creating a cyclic dependency between the `Item` implementation and its serialization method.
+  - It's relatively easy to write a replacement method to encode items to JSON as you desire.
+  - `Item::legacyJsonDeserialize()` (previously `Item::jsonDeserialize()`) is retained to allow loading legacy data, although it may be removed in the future.
+- The following classes have been removed:
+  - `Bed`
+  - `ItemFactory`
+  - `ItemIds`
+  - `Skull`
+- The following classes have been added:
+  - `BoatType` - enum of all boat types
+  - `CoralFan`
+  - `HoneyBottle`
+  - `MedicineType`
+  - `Medicine`
+  - `Spyglass`
+  - `SuspiciousStewType`
+  - `SuspiciousStew`
+- The following API methods have been added:
+  - `protected Item->describeState(RuntimeDataDescriber $w) : void` 
+  - `public Armor->clearCustomColor() : $this` - clears the custom color of an armor item
+  - `public ArmorTypeInfo->getToughness() : int`
+  - `public ArmorTypeInfo->isFireProof() : bool`
+  - `public Boat->getType() : BoatType`
+  - `public Dye->setColor(\pocketmine\block\utils\DyeColor $color) : $this`
+  - `public Item->getStateId() : int` - returns a runtime numeric state ID for comparisons including information such as coral type, dye color, etc. - DO NOT save this to disk or databases
+  - `public Item->getTypeId() : int` - returns a runtime numeric type ID for comparisons - DO NOT save this to disk or databases
+  - `public Item->isFireProof() : bool`
+  - `public ItemIdentifer->getTypeId() : int`
+  - `public Potion->setType(PotionType $type) : $this`
+  - `public SplashPotion->setType(PotionType $type) : $this`
+  - `public StringToItemParser->lookupAliases(Item $item) : list<string>` - returns a list of all registered aliases for the given item
+  - `public StringToItemParser->lookupBlockAliases(Block $block) : list<string>` - returns a list of all registered aliases for the given block
+  - `public static ItemIdentifier::fromBlock(Block $block) : self`
+- The following API methods have been removed:
+  - `Boat->getWoodType()`
+  - `Item->getId()` - for type comparisons, use `Item->getTypeId()` instead
+  - `Item->getMeta()` - use the item's specific API methods to compare information such as colour, potion type etc.
+  - `Item->hasAnyDamageValue()` - for meta wildcard recipe ingredients, use `pocketmine\crafting\MetaWildcardRecipeIngredient` instead
+  - `ItemIdentifier->getId()`
+  - `ItemIdentifier->getMeta()`
+- The following API methods have been renamed:
+  - `Item::jsonDeserialize()` -> `Item::legacyJsonDeserialize()`
+- The following API methods have signature changes:
+  - `ArmorTypeInfo->__construct()` now accepts optional parameters `int $toughness` and `bool $fireProof`
+  - `BoatType::__construct()` now accepts `BoatType $boatType` instead of `TreeType $woodType`.
+  - `Item->onAttackEntity()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onClickAir()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onDestroyBlock()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onInteractBlock()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onReleaseUsing()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `ItemIdentifier->__construct()` no longer accepts a `$variant` parameter, and now expects an item type ID for the ID parameter
+  - `LegacyStringToItemParser->addMapping()` now accepts a string for ID, instead of an integer
+- The following API methods have behaviour changes:
+  - `Item->equals()`'s `$checkDamage` parameter is now ignored, as tool damage is now stored as an NBT tag. This parameter wasn't removed due to being followed by a second `bool` parameter, which would potentially end up in the wrong place and silently cause bugs in updated plugins.
+  - `Item->equals()`'s `$checkTags` parameter will now cause tool and armor damage to be checked if true.
+- The following enums have new members:

+  - `Player->kick()` now accepts an additional `Translatable|string|null $disconnectScreenMessage` parameter, which is the message to be displayed on the disconnect screen (the message in `$reason` is used if null is passed)
+  - `Player->sendJukeboxPopup()` now accepts `Translatable|string` instead of `string, string[]`
+- The following classes have been removed:
+  - `PlayerChunkLoader` - deprecated in 4.19.0 (this was technically internal, but never marked as such)
+
+### `pocketmine\player\chat`
+- The following new classes have been added:
+  - `ChatFormatter` - interface implemented by chat formatters - this is far more powerful than the old API
+  - `LegacyRawChatFormatter` - implements the same behaviour previously used by `PlayerChatEvent->setFormat()`
+  - `StandardChatFormatter` - formats chat messages in the vanilla Minecraft style
+
+### `pocketmine\scheduler`

+- The following public properties have been renamed:
+  - `Explosion->size` -> `Explosion->radius`
+
+### `pocketmine\world\format`
+- Chunks are now considered dirty (modified) by default, unless loaded from a `WorldProvider` by `World`. Previously, chunks were considered unmodified by default, which allowed several pathways to bugs.
+- The following classes have been added:
+  - `io\GlobalBlockStateHandlers` - gives access to block data serializer, deserializer, and upgraders
+  - `io\GlobalItemDataHandlers` - gives access to item data serializer, deserializer, and upgraders
+  - `io\LoadedChunkData` - represents a chunk loaded from disk, along with information such as whether the chunk was upgraded and what fixes it requires
+- The following new API methods have been added:
+  - `public SubChunk->getBiomeArray() : PalettedBlockArray`
+- The following classes have been removed:
+  - `BiomeArray` - `PalettedBlockArray` is now used for 3D biome data
+- The following API methods have changed signatures:
+  - `Chunk->getBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`
+  - `Chunk->setBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`

+- The following API methods have been removed:
+  - `NoteInstrument::fromMagicNumber()`
+  - `NoteInstrument->getMagicNumber()`
+
+## Internals
+- All external usages of `KnownTranslationKeys` are now removed. All localized messages are now sent using `Translatable` objects (usually from `KnownTranslationFactory`).
+- All usages of NBT keys now use class constants instead of hardcoded strings (except for an occasional overlooked one).
+- Built-in commands now declare their names inside the class constructor, rather than accepting them as parameters. This improves code consistency.
+- Commands now use an array for permissions internally, instead of a string separated by `;`.
+- Make use of `Item->canStackWith()` instead of `Item->equals()` wherever possible, to make the code more readable.
+- Moved command timings to `Timings`.
+- Overriding of serializers and deserializers of items and blocks is now consistently disallowed. Since overriding stuff is non-cooperative, it doesn't make any sense in plugins, which must coexist with other plugins. If you want to modify the functionality of built-in stuff, you have several alternative options:
+    - Use existing API (e.g. events, API methods) - most uses of overrides in PM4 and earlier were abuses that could have been done with events
+    - Submit feature proposals or pull requests for new API to be added (e.g. new events)
+    - Register completely custom items, and reuse behaviour from the item you want to mimic
+    - Fork PocketMine-MP and alter the code directly - this way your plugins aren't pretending to be cooperative with other plugins
+- `level.dat`, block, item, entity, tile and chunk data are now tagged with a version ID as per `VersionInfo::WORLD_DATA_VERSION`. This allows the server to apply fixes to older worlds if necessary.
+- Protocol creative inventory entries are now cached in `CreativeInventoryCache` to improve performance of initial join and game mode changes.
+- Singletons in the `pocketmine\network\mcpe\convert` package have been centralized under `TypeConverter`. In the future, this will be injected where needed, allowing different converters to be used for different sessions (useful for multiversion).
+- `BlockStateDictionary` memory usage is now reduced from 9 MB to 3.5 MB using various techniques, including string reuse and binary-encoded states.
+- `NetworkSession` disconnect APIs now accept `Translatable|string` instead of `string` to allow localized disconnect messages.
+- `NetworkSession` disconnect methods have been altered to allow specifying a different disconnect reason and disconnection screen message.
+- `RuntimeBlockMapping` has been renamed to `BlockTranslator`.

+
+**Plugin compatibility:** Plugins for previous 5.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe`  or `pocketmine\data` namespace.

+
+## General
+- PHP 8.2 is now used by default. PHP 8.1 is still supported, but will be removed in a future 5.x release.
+- Improved timings reports by removing `Breakdown` timings group. This group serves no purpose with tree timings and made for confusing reading.
+
+## Performance
+- Improved performance of `Block::encodeFullState()` in most conditions. This in turn improves performance of `World::setBlock()` and `World::setBlockAt()`.
+- Improved network compression performance by avoiding unnecessary object allocations.
+- Timings now report time spent in individual `Snooze` handlers, making it easier to debug performance issues.
+
+## Gameplay
+### Blocks
+- Implemented crop growth speed modifiers.
+  - The following things now positively affect crop growth speed:
+    - Being planted on or being adjacent to farmland (hydrated farmland offers a larger benefit than dry farmland)
+    - Potential light level of at least 9
+    - Being planted in rows with space between them (or a different type of crop)
+  - The following things now negatively affect crop growth speed:
+    - Improper arrangement (e.g. the same crop on all sides)
+    - Insufficient light level (below 9)
+  - Poorly arranged crops will grow slower in this version. Past versions behaved as if crops were always planted in ideal conditions.
+  - Crops planted in ideal conditions will grow at the same speed as before.
+
+### Items
+- Added the following new items:
+  - All types of Smithing Template
+- Pitcher Pod is now correctly registered. In previous versions, it was mapped to the Pitcher Crop block, causing incorrect name display in commands.
+
+## Internals
+- Cleaned up various getter usages where direct property access is possible.
+- Avoided unnecessary repeated getter calls in some loops.
+- `NetworkSession` may now track `string` instead of `CompressBatchPromise` when a batch was synchronously compressed. This significantly reduces object allocations and improves performance.
+- `NetworkSession` now sends less information to clients on login validation failure. This avoids leaking potentially sensitive error information to clients.
+  - Clients can correlate their disconnects with server-side logs using the `Error ID` shown on the disconnect screen.

+- Fixed ordering of property values generated by `tools/generate-block-palette-spec.php`.
+
+## API
+### `pocketmine\block`
+- The following new classes have been added:
+  - `utils\LightableTrait` - used by blocks with `getLit()` and `setLit()` methods
+- The following methods have been deprecated:
+  - `Block->isSolid()` - this method returns confusing results which don't match expectations and no one really knows what it actually means
+- `CocoaBlock` now extends `Flowable` to match vanilla Minecraft behaviour.
+
+### `pocketmine\plugin`
+- `PluginManager->registerEvent()` now throws an exception when given a generator function for the event handler.
+- `PluginManager->registerEvents()` now throws an exception if any of the detected event handlers are generator functions. Use `@notHandler` to have the function ignored if intended.
+
+### `pocketmine\promise`
+- The following methods have been added:
+  - `public static Promise::all(list<Promise> $promises) : Promise` - returns a promise that is resolved once all given promises are resolved, or is rejected if any of the promises are rejected.
+
+### `pocketmine\scheduler`
+- The following methods have been deprecated:
+  - `AsyncWorker->getFromThreadStore()` - use class static properties for thread-local storage
+  - `AsyncWorker->removeFromThreadStore()`
+  - `AsyncWorker->saveToThreadStore()`
+
+## Documentation
+- Improved documentation of various methods in `Block`.
+
+## Gameplay
+- The following new items have been added:
+  - Name Tag
+
+## Internals
+- Removed specialization of shutdown logic for `Thread` vs `Worker` (no specialization is required).
+- Authentication system no longer accepts logins signed with the old Mojang root public key.
+- ID to enum mappings in `pocketmine\data` now use a new `match` convention to allow static analysis to ensure that all enum cases are handled.
+- Updated version of `pocketmine/bedrock-protocol` allows avoiding decoding of some itemstack data from the client in most cases, improving performance.
+
+# 5.12.1
+Released 13th March 2024.
+
+## Fixes
+- Fixed `Player Network Receive - Decompression` timings not being stopped correctly when receiving an uncompressed packet.
+
+## Internals
+- Removed hardcoded batch packet size limit. This was already covered by other limits anyway.

+# 5.14.0
+Released 5th April 2024.
+
+**For Minecraft: Bedrock Edition 1.20.70**
+
+This is a minor feature release, including performance improvements, minor gameplay features, new API features, and various internal improvements.
+
+**Plugin compatibility:** Plugins for previous 5.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe`  or `pocketmine\data` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## General
+- Added support for a `--no-log-file` command-line option, which disables the creation of a `server.log` file.
+  - **Use this with caution.** If you don't have another mechanism for collecting logs (e.g. Docker), this may make debugging harder.
+- Added support for automatic `server.log` rotation. When the `server.log` exceeds 32 MB, it will be renamed and moved to the `log_archive` folder in the server's data directory.
+  - Files in the `log_archive` folder can be safely modified or deleted without stopping the server.
+  - We suggest a cron job or similar to manage old log files (e.g. deleting or compressing them).
+- Added a new cache mechanism for `PocketMine-MP.phar`. This has several advantages:
+  - Caches are now reused by all threads - this significantly reduces `/tmp` usage (previously every thread generated its own cache, wasting lots of space)
+  - Dead cache files are automatically cleaned up by new servers - this means that a server crash loop won't flood `/tmp` anymore
+- `/status` now reports a more accurate number of threads on Windows.
+- Large resource packs are now able to be properly downloaded from the server.
+- Larger player skin sizes are now accepted by the server.
+- Improved logging from world providers to reduce spam when chunks contain invalid data.
+- Added more error logging for Anvil, PMAnvil and MCRegion worlds.
+- PHP deprecation warnings no longer cause the server to crash. This should make it easier for server owners to update to newer PHP versions.
+
+## Performance
+- Improved world loading performance. This was achieved through a combination of changes:
+  - Improvements to `BlockStateUpgrader` to avoid unnecessary work
+  - Improvements to `BlockStateUpgradeSchema` to clean up stupid code
+  - Improvements to `BlockStateReader` unused state handling
+  - Optimizations to `RegistryTrait` (see below)
+- Improved performance of `RegistryTrait::__callStatic()` accessor by introducing a fast-path optimization. Ensure that you access registries with the correct function name case to benefit from this.
+  - This improves the performance of `VanillaBlocks::WHATEVER()`, `VanillaItems`, etc.
+
+## Tools
+- `tools/generate-blockstate-upgrade-schema.php` now supports generating schemas using `flattenedValueRemaps` (described in [BlockStateUpgradeSchema](https://github.com/pmmp/BedrockBlockUpgradeSchema/releases/tag/4.0.0)).
+
+## Gameplay
+- Added sounds for armour equipping and unequipping.
+- Added sound for picking berries from a sweet berry bush.
+
+## API
+### `pocketmine\block\utils`
+- The following enum cases have been added:
+  - `BannerPatternType::GLOBE`
+  - `BannerPatternType::PIGLIN`
+
+### `pocketmine\event\player`
+- The following classes have been added:
+  - `PlayerResourcePackOfferEvent` - called before the server tells a connecting client which resource packs are available to download - allows customizing the pack list and other options
+
+### `pocketmine\item`
+- The following API methods have been added:
+  - `public ArmorMaterial->getEquipSound() : ?\pocketmine\world\Sound` - returns the sound to play when this armour is equipped or unequipped
+- The following API methods have signature changes:
+  - `ArmorMaterial->__construct()` now accepts an optional `?Sound $equipSound` parameter
+
+### `pocketmine\utils`
+- The following API methods have signature changes:
+  - `MainLogger->__construct()` now accepts `null` for the `$logFile` parameter - this disables the creation of a logger thread and log file
+  - `MainLogger->__construct()` now accepts an optional `?string $logArchiveDir` parameter. If set, this enables log archiving in the specified directory when the current log file exceeds 32 MB.
+
+## Dependencies
+- Now uses [`pocketmine/bedrock-block-upgrade-schema` version 4.0.0](https://github.com/pmmp/BedrockBlockUpgradeSchema/releases/tag/4.0.0).
+- Now uses [`pmmp/ext-pmmpthread` version 6.1.0](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.1.0).
+- Now uses [`pocketmine/errorhandler` version 0.7.0](https://github.com/pmmp/ErrorHandler/releases/tag/0.7.0).
+- Now uses [`pocketmine/raklib` version 1.1.0](https://github.com/pmmp/RakLib/releases/tag/1.1.0).
+- Now uses [`pocketmine/raklib-ipc` version 1.0.0](https://github.com/pmmp/RakLibIpc/releases/tag/1.0.0).
+
+## Internals
+- (Re)Added support for RakLib packet ACK receipts. This was used to throttle resource pack sending and prevent network overloading.
+  - Added `NetworkSession->sendDataPacketWithReceipt()` to make use of this feature.
+  - `PacketSender` now requires an additional `?int $receiptId` parameter.
+- `ResourcePackPacketHandler` now uses `sendDataPacketWithReceipt()` to send resource packs, and delays sending the next chunk until the current one is acknowledged.
+- `ResourcePackPacketHandler` now accepts resource pack info directly in the constructor, instead of `ResourcePackManager`. This eases the implementation of `PlayerResourcePackOfferEvent`.
+- Increased `ZlibCompressor::DEFAULT_MAX_DECOMPRESSION_SIZE` to 8 MB (previously 2 MB). While this weakens server security, it appears to be necessary to deal with extremely bloated Persona skins.
+- Increased max split packet parts accepted by `RakLib` to 512 (previously 128). Again, this is necessary to deal with extremely bloated Persona skins.
+- Added a new cache mechanism for `PocketMine-MP.phar`.
+  - `ext-phar`'s default mechanism is extremely wasteful (generating a separate cache file per thread), and doesn't clean up after itself.
+  - The new cache mechanism is shared between all threads, and automatically cleans up stale caches.
+  - The phar stub (`build/server-phar-stub.php`) now converts the phar contents into a `.tar`, and decompresses all the files into `$TMPDIR/PocketMine-MP-phar-cache.<random>/`.
+  - `phar://` URIs still work with this system, but `new Phar(__FILE__)` must be replaced by `new PharData(__FILE__)` within PocketMine-MP core code.
+  - Backtraces from a `phar`'d server will now point to a location in the extracted phar cache, rather than the phar itself.
+- `block_factory_consistency_check` test (actually for `RuntimeBlockStateRegistry`) now stores less data, and is no longer affected by changes to internal state ID construction.
+
+# 5.14.1
+Released 5th April 2024.
+
+## Fixes
+- Fixed incorrect `pmmpthread` version check in server bootstrap.

+
+**For Minecraft: Bedrock Edition 1.20.0**
+
+This is a minor technical update, including changes to AsyncTask error handling and support for BedrockBlockUpgradeSchema version 3.0.0.
+
+**Plugin compatibility:** Plugins for previous 5.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe`  or `pocketmine\data` namespace.

+
+## Core
+- [BedrockBlockUpgradeSchema version 3.0.0](https://github.com/pmmp/BedrockBlockUpgradeSchema/releases/tag/3.0.0) is now supported.
+- [`ext-pmmpthread` version 6.0.4](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.0.4) is now required (bug fixes required to support technical changes in this release).
+
+## Performance
+- Improved performance of `AsyncPool->submitTask()` and `AsyncPool->submitTaskToWorker()`.
+- Added new timings for `AsyncTask->onProgressUpdate()` and `AsyncTask->onCompletion()`.
+
+## Gameplay
+### Blocks
+- Added the following new blocks:
+  - Cherry Button
+  - Cherry Door
+  - Cherry Fence
+  - Cherry Fence Gate
+  - Cherry Leaves
+  - Cherry Log
+  - Cherry Planks
+  - Cherry Pressure Plate
+  - Cherry Sign
+  - Cherry Slab
+  - Cherry Stairs
+  - Cherry Trapdoor
+  - Cherry Wood
+  - Glow Lichen
+  - Piglin Head
+
+## Tools
+- `generate-block-upgrade-schema.php` now supports generating schemas a la BedrockBlockUpgradeSchema version 3.0.0, using `newFlattenedName` to reduce schema size.
+- Improved property remapping detection in `generate-block-upgrade-schema.php`. It now detects related properties with more confidence (even when multiple properties were change), and no longer considers unrelated properties as mapped (e.g. `mapped_type` and `deprecated` in 1.9->1.10).
+
+## API
+### `pocketmine\data\bedrock\block`
+- The following new API methods have been added:
+  - `public BlockStateData->toVanillaNbt() : CompoundTag` - returns the NBT for the blockstate without any PMMP extra metadata (`toNbt()` will normally include a `PMMPDataVersion` tag).
+
+### `pocketmine\data\runtime`
+- The following new API methods have been added:
+  - `public RuntimeDataDescriber->facingFlags(list<int> $faces) : void`
+
+### `pocketmine\scheduler`
+- `AsyncTask->onRun()` no longer tolerates uncaught exceptions.
+  - This means that any uncaught exceptions thrown from `AsyncTask->onRun()` will now crash the worker thread, and by extension, the server.
+  - This change makes it easier to debug errors by detecting them earlier.
+- The following API methods have been deprecated:
+  - `AsyncTask->onError()`
+
+## Internals
+- `AsyncTask->progressUpdates` is now lazily initialized when a task publishes a progress update.
+  - This was previously not possible due to technical limitations of the `ext-pmmpthread` extension.
+  - This change improves performance of `AsyncPool->submitTask()` and `AsyncPool->submitTaskToWorker()`, as well as reducing the amount of work needed to check for progress updates on tick.
+- Errors in `AsyncWorker` now cascade and crash the whole server.
+  - This makes it easier to debug errors by detecting them earlier.
+  - This includes all types of unexpected errors, such as OOM, uncaught exceptions, etc.
+  - This change is not expected to affect normal server operation, as worker threads are not expected to crash under normal circumstances.
+- `AsyncTask::$threadLocalStorage` now uses a plain `array` instead of `ArrayObject`. The `ArrayObject` was a workaround for `ext-pthreads` to prevent thread-locals getting copied to the worker thread, and is no longer necessary.
+- Regenerated `pocketmine\data\bedrock\item\ItemTypeNames` for Bedrock 1.20 (BC breaking, some item names have changed).
+- Fixed `build/generate-item-type-names.php` not including some newer blockitems, such as doors and hanging signs.
+
+# 5.2.1
+Released 11th July 2023.
+
+**This release includes changes from the following releases:**
+- [4.22.3](https://github.com/pmmp/PocketMine-MP/blob/4.22.3/changelogs/4.22.md#4223) - Fixes for some crash issues

+  - The following new classes have been added:
+    - `transaction\action\SlotValidator` - interface
+    - `transaction\action\CallbackSlotValidator` - class allowing a closure to be used for slot content validation
+    - `SlotValidatedInventory` - implemented by inventories which support the use of slot validators
+
+### `pocketmine\item`

+  - `ItemCooldownTags` - list of cooldown group tags used by PocketMine-MP
+
+### `pocketmine\world\sound`

+
+## Tools
+- `tools/blockstate-upgrade-schema-utils.php` (formerly `generate-blockstate-upgrade-schema.php`) has several improvements:

+
+## Interim releases
+If you're upgrading directly from 5.1.x to 5.3.x, please also read the following changelogs, as the interim releases contain important changes:

+
+## Internals
+- `BlockTypeNames`, `BlockStateNames`, `BlockStateStringValues` and `ItemTypeNames` in the `pocketmine\data\bedrock` package have BC-breaking changes to accommodate Bedrock 1.20.10.

+- [4.23.1](https://github.com/pmmp/PocketMine-MP/blob/4.23.1/changelogs/4.23.md#4231) - Security fixes
+
+## General
+- Updated `build/php` submodule to pmmp/PHP-Binaries@e0c918d1379465964acefd562d9e48f87cfc2c9e.
+
+# 5.3.2

+
+## Documentation
+- Fixed documentation error in `StringToTParser`.
+
+## Fixes

+
+# 5.3.3
+Released 24th July 2023.
+
+## Included releases
+**This release includes changes from the following releases:**
+- [4.23.3](https://github.com/pmmp/PocketMine-MP/blob/4.23.3/changelogs/4.23.md#4233) - Various bug fixes
+
+## Fixes
+- Added a workaround for PM4 worlds with chunks corrupted by [Refaltor77/CustomItemAPI](https://github.com/Refaltor77/CustomItemAPI).
+  - While this was not the fault of PocketMine-MP itself, a significant number of users were affected by this problem.
+  - This error was not detected by PM4 due to missing validation of certain data which should not have existed in 1.12.
+  - An error will now be logged when this corruption is detected, but the affected chunks should otherwise load normally.
+- Relaxed validation of expected 3D biome array counts per chunk in LevelDB worlds.
+  - Vanilla Bedrock currently saves 24 palettes (and only 24 are required), but it saved 25, 32, or 64 biome palettes per chunk in older versions.
+  - Core validation for these padding biomes was very strict, enforcing exact compliance with vanilla.
+  - Since only 24 palettes are actually required, the remaining palettes may now be omitted irrespective of the chunk version.
+  - An error will still be logged when this mistake is detected, but the affected chunks will otherwise load normally.
+- Fixed `/kill` not working on players who had (re)spawned in the 3 seconds immediately after (re)spawning (due to `noDamageTicks`).
+- Fixed `/kill` not working correctly for players with high levels of Health Boost or other health-altering effects.
+- Fixed netherite items being destroyed by lava.
+- Fireproof entities no longer display the burning animation when in fire or lava. This does not apply to creative players, who are immortal rather than being fireproof.
+- Fixed frosted ice melting in certain conditions which didn't match vanilla Bedrock.
+
+# 5.3.4
+Released 1st August 2023.
+
+## Included releases
+This release includes changes from the following releases:
+- [4.23.4](https://github.com/pmmp/PocketMine-MP/blob/4.23.4/changelogs/4.23.md#4234) - Item entity lag fix
+
+This release contains no other significant changes.

+# 5.4.0
+Released 1st August 2023.
+
+**For Minecraft: Bedrock Edition 1.20.10**
+
+This is a minor feature update, including a handful of new gameplay features, new plugin APIs and improvements to error reporting.
+
+**Plugin compatibility:** Plugins for previous 5.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe`  or `pocketmine\data` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## General
+- Improved error reporting for async task and thread crashes.
+- Players may now have different creative inventories.
+
+## Gameplay
+### General
+- Added support for 1.5-block height sneaking.
+- Fixed missing player arm swing and sounds when punching the air.
+
+### Blocks
+- Implemented the following new blocks:
+  - Big Dripleaf Head
+  - Big Dripleaf Stem
+  - Small Dripleaf
+- Acacia saplings now grow into acacia trees.
+- Fixed melon and pumpkin stems not attaching to the correct block when growing.
+- Various blocks now drop more items when mined with a compatible tool enchanted with Fortune.
+
+### Items
+- Implemented Strong Slowness potion.
+- Implemented Fortune enchantment.
+
+## API
+### `pocketmine\block`
+- The following new classes have been added:
+  - `utils\FortuneDropHelper` - utility methods for calculating the drop counts for Fortune-affected blocks
+- The following new API methods have been added:
+  - `protected Block->getAdjacentSupportType(int $facing) : utils\SupportType` - returns the type of support provided by the block in the given direction on the adjacent face
+
+### `pocketmine\entity`
+- The following new API constants have been added:
+  - `Living::DEFAULT_KNOCKBACK_FORCE`
+  - `Living::DEFAULT_KNOCKBACK_VERTICAL_LIMIT`
+
+### `pocketmine\entity\animation`
+- `ConsumingItemAnimation` now accepts `Living` instances instead of just `Human`.
+
+### `pocketmine\event`
+- The following new classes have been added:
+  - `PlayerMissSwingEvent` - called when the player attempts the attack action (left click on desktop) without any target
+    - This is possible thanks to the introduction of new flags in `PlayerAuthInputPacket` in Bedrock 1.20.10
+- The following new API methods have been added:
+  - `public EntityDamageByEntityEvent->getVerticalKnockBackLimit() : float`
+  - `public EntityDamageByEntityEvent->setVerticalKnockBackLimit(float $verticalKnockBackLimit) : void` - sets the max vertical velocity that can result from the victim being knocked back
+
+### `pocketmine\player`
+- The following new API methods have been added:
+  - `public Player->getCreativeInventory() : pocketmine\inventory\CreativeInventory`
+  - `public Player->setCreativeInventory(pocketmine\inventory\CreativeInventory $inventory) : void`
+  - `public Player->missSwing() : void` - performs actions associated with the attack action when there is no target (see `PlayerMissSwingEvent`)
+
+### `pocketmine\scheduler`
+- Cancellation functionality has been removed from `AsyncTask`, as it didn't make any sense and wasn't used by anything for what it was intended for.
+  - It broke sequential task execution - later tasks might depend on state from earlier tasks
+  - It didn't actually cancel the task anyway - at best, it prevented it from running, but couldn't interrupt it (though interrupting a task does not make sense either)
+- The following API methods have been deprecated, and their functionality has been removed:
+  - `AsyncTask->hasCancelledRun()`
+  - `AsyncTask->cancelRun()`
+
+## Internals
+- Uncaught exceptions and fatal errors in `AsyncTask`, threads extending `pocketmine\thread\Thread`, and `pocketmine\thread\Worker` are now recorded in crashdumps, making it significantly easier to debug errors in these areas.
+- JWT signature DER <-> raw conversions are now handled in-house using code in `JwtUtils`
+  - Due to the simplicity of the conversion and only requiring a tiny subset of the ASN.1 spec, it didn't make much sense to introduce another dependency.
+  - `fgrosse/phpasn1` is no longer required. This package was abandoned by its author and only used by PocketMine-MP for this one purpose.
+- Various usages of `Closure::fromCallable()` have been replaced by PHP 8.1 first-class callable syntax.
+- Blocks requiring support shifted to a "can be supported at" model, rather than "can be supported by".
+  - This model reduces repeated logic when placing and performing nearby block updates (no need to hardcode facing everywhere).
+  - In addition, this change facilitates the use of the newly introduced `Block->getAdjacentSupportType()` API method, reducing boilerplate support-type checking code.
+- Bell block code has been simplified and cleaned up.
+- `TallGrass` and `DoubleTallGrass` now use a shared `TallGrassTrait` to reduce code duplication.
+
+# 5.4.1
+Released 8th August 2023.
+
+## General
+- Updated translation data to [pmmp/Language 2.19.6](https://github.com/pmmp/Language/releases/tag/2.19.6).
+- [`ext-pmmpthread` 6.0.7](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.0.7) is now required (needed for bug fixes).
+
+## Fixes
+- Fixed Podzol not dropping itself when mined with Silk Touch.
+- Fixed `World->getSafeSpawn()` not accepting positions below `y=0` (world height limit change).
+- Fixed `pocketmine\thread\Thread` and `pocketmine\thread\Worker` instances not logging any information when they crash.
+- Fixed `CraftItemEvent` not cloning returned items.
+
+## Internals
+- Foreach by-reference is now disallowed via a custom PHPStan rule.
+
+# 5.4.2
+Released 9th August 2023.
+
+## Included releases
+- [4.23.5](https://github.com/pmmp/PocketMine-MP/blob/4.23.5/changelogs/4.23.md#4235) - Minor bug fixes
+
+## Fixes
+- Fixed cake accepting candle placement when slices have already been eaten.
+- Fixed fire charges not lighting candles.
+
+# 5.4.3
+Released 21st August 2023.
+
+## Included releases
+- [4.23.6](https://github.com/pmmp/PocketMine-MP/blob/4.23.6/changelogs/4.23.md#4236) - Armor inventory client bug workaround
+
+## Fixes
+- Fixed crashdumps not generating correctly on fatal errors.
+- Fixed `PotionCauldron::setPotionItem()` not validating the item type.
+- Fixed chorus fruit not considering teleport destinations below y=0.
+- Fixed cake dropping itself when mined.
+
+# 5.4.4
+Released 6th September 2023.
+
+## General
+- Crashdumps caused by non-phar plugins are now submitted to the Crash Archive, the same as other plugins. Previously, non-phar plugin crashes would not be submitted, causing maintainers to potentially miss important issues.
+
+## Fixes
+- Fixed player Y coordinates sometimes being slightly below the top of the block they were standing on (floating point error due to subtracting eye height).
+- Fixed template slot of smithing tables not accepting any items.
+- `tools/generate-bedrock-data-from-packets.php` is now significantly less spammy when warning about duplicated recipes.
+- Fixed empty stack traces in `lastError` data of crashdumps.

+
+## Dependencies
+- Updated `pocketmine/math` dependency to [`1.0.0`](https://github.com/pmmp/Math/releases/tag/1.0.0).
+- Updated `pocketmine/nbt` dependency to [`1.0.0`](https://github.com/pmmp/NBT/releases/tag/1.0.0).
+
+## Performance
+- Some events are now no longer fired if no handlers are registered.
+  - This improves performance by avoiding unnecessary object allocations and function calls.
+  - Events such as `DataPacketReceiveEvent`, `DataPacketSendEvent` and `PlayerMoveEvent` are optimized away almost completely by this change, offering some much-needed performance gains.
+- Significantly improved performance of small moving entities, such as dropped items.
+  - This was achieved by a combination of changes, which together improved observed performance with 2000 item entities moving in water by 30-40%.
+  - The benefit of this will be most noticeable in SkyBlock servers, where large cactus farms can generate thousands of dropped items.
+- `World->getCollisionBoxes()` now uses an improved search method, which reduces the work done by the function by almost 90% for small entities.
+  - This improves performance of collision detection for small entities, such as dropped items.
+
+## Gameplay
+### General
+- Implemented enchanting using an enchanting table (yes, finally!)
+  - Thanks to [@S3v3Nice](https://github.com/S3v3Nice) for investing lots of time and effort into developing this.
+  - Since this feature is quite complex, it's possible there may be bugs. Please be vigilant and report any issues you find.
+
+### Blocks
+- The following new blocks have been implemented:
+  - Pink Petals
+- Pressure plates are now functional, in the sense that they react when entities stand on them and perform the correct logic.

+
+## General
+- Added support for Minecraft: Bedrock Edition 1.20.30.
+- Removed support for older versions.
+
+## Fixes
+- Fixed support conditions for hanging roots, cave vines and dead bushes.
+- Fixed connection conditions for fences, glass panes, iron bars, and walls.
+
+# 5.6.1
+Released 20th October 2023.
+
+## Performance
+- Improved performance of cactus growth by disabling neighbour updates when only the age property was updated. While this isn't a perfect solution, it provides significant performance gains for servers with large cactus farms.
+
+## Fixes
+- Fixed `tools/generate-bedrock-data-from-packets.php` incorrectly interpreting network meta as blockstates in some cases (broken crafting recipes).
+- Fixed crafting recipes involving beds, skulls and some other items not working correctly (incorrectly interpreted data).
+- Fixed crashes when flower pot or cauldron blockentities exist in places where they shouldn't (leftovers from upgraded PM3 worlds).
+- Fixed `Entity->broadcastSound()` not firing `WorldSoundEvent` (bypassing internal sound system).
+- Fixed wooden signs, buttons and doors not being able to be used as furnace fuel.
+- Fixed bone meal and tools only working when used on the top side of dirt and grass. Bone meal now works from any side, and tools work on any side except the bottom.

+
+## General
+- Neighbour block updates now have a separate timer for timings. Previously, these were counted under `Scheduled Block Updates`, which was misleading.
+
+## Performance
+- `LightUpdate` now avoids attempting to propagate back in the same direction the light came from. This produces a small performance improvement of around 6% in light propagation.
+- Improved worst-case (non-cached) performance of `World::getCollisionBlocks()` (and its successor `World::getBlockCollisionBlocks()`).
+  - While 5.5.0 introduced caching at the `World` level for AABBs, the cache was rarely useful due to entity and player movement being too unpredictable. This meant that most users saw a performance degradation with lots of moving entities, except in specific situations.
+  - Performance for fetching non-cached AABBs for a cell is now improved by 2x. Overall performance benefit to a server depends on the number of entities and players.
+- Added cache for hydrated farmland blocks to remember the last known location of nearby water.
+  - If nearby water sources are not changed, this cache allows hydrated farmland to completely avoid checking up to 161 nearby blocks for water after the first check.
+  - Tests with large wheat farms showed a 25% performance improvement in overall server performance compared to previous 5.x versions.
+- Migrated various internal enums to native PHP 8.1 enums. Bypassing magic `__callStatic()` accessors improved performance in many areas, although it's hard to quantify the exact benefit.
+- Made use of `Facing::OFFSET` constant in various places to avoid unnecessary `Vector3` and `Position` object allocations. Many pathways benefit from this, including neighbour block updates (due to faster `Block::getSide()` and less useless objects).
+- Avoided clearing block AABB caches except when strictly necessary. Previously, the cache was wiped every time blocks were read from the world, making them mostly useless.
+- Avoided random updates on blocks which have reached their final state, such as fully-grown crops. This produces a minimal performance improvement.
+- Removed useless checks in some `World` hot paths.
+
+## API
+### General
+- All enums have been migrated to native PHP 8.1 enums.
+  - For now, the old APIs and accessors are still usable (via `LegacyEnumShimTrait`), but these will be removed in the next major release.
+  - `EnumTrait` has been deprecated, and will be removed in the next major release.
+  - Migration for most plugin developers will simply involve deleting `()` from the end of enum case usages, which is a trivial change and also improves performance.
+  - Plugin usages of `EnumTrait` are encouraged to move to native enums, optionally using `LegacyEnumShimTrait` to provide backwards compatibility.
+    - See [this code](https://github.com/pmmp/PocketMine-MP/blob/9832fe899f13a8ea47cc9d73de7088f7775a12f5/src/block/utils/DyeColor.php#L85-L107) for an example of how to associate properties with enum cases (since native enums don't support this directly).
+  - Thanks to improvements in `RuntimeDataDescriber`, any native enum can now be used as a custom block's state property.
+
+### `pocketmine\block`
+- The following classes have been added:
+  - `utils\AgeableTrait` - used by blocks which have an age property, such as crops
+  - `utils\StaticSupportTrait` - used by blocks which have the same support requirements regardless of their state, such as crops
+
+### `pocketmine\data\runtime`
+- The following API methods have been added:
+  - `public RuntimeDataDescriber->boundedIntAuto(int $min, int $max, int &$value) : void` - similar to `boundedInt()`, but automatically calculates the needed number of bits based on the given min/max
+  - `public RuntimeDataDescriber->enum(T extends \UnitEnum &$case) : void` - describes any native PHP 8.1 enum case
+  - `public RuntimeDataDescriber->enumSet(array<int, T extends \UnitEnum> &$set, array<int, T extends \UnitEnum> $allCases) : void` - describes a set of enum cases (similar to bitflags)
+- The following API methods have been deprecated:
+  - `RuntimeDataDescriber->bellAttachmentType()` - use `enum()` instead
+  - `RuntimeDataDescriber->boundedInt()` - use `boundedIntAuto()` instead
+  - `RuntimeDataDescriber->brewingStandSlots()` - use `enumSet()` instead
+  - `RuntimeDataDescriber->copperOxidation()` - use `enum()` instead
+  - `RuntimeDataDescriber->coralType()` - use `enum()` instead
+  - `RuntimeDataDescriber->dirtType()` - use `enum()` instead

+  - `RuntimeDataDescriber->potionType()` - use `enum()` instead
+  - `RuntimeDataDescriber->slabType()` - use `enum()` instead
+  - `RuntimeDataDescriber->suspiciousStewType()` - use `enum()` instead
+
+### `pocketmine\player`
+- `TitleID` is now included in `PlayerInfo` metadata for plugin consumption.
+
+### `pocketmine\world`
+- The following API methods have been added:
+  - `public World->getBlockCollisionBoxes(AxisAlignedBB $bb) : list<AxisAlignedBB>` - similar to `getCollisionBoxes` but exclusively for blocks, avoiding the need for conditionally useless parameters
+- The following API methods have been deprecated:
+  - `World->getCollisionBoxes()` - use `getBlockCollisionBoxes()` instead (alongside `getCollidingEntities()` if entity collision boxes are also required)
+
+### `pocketmine\utils`
+- The following classes have been deprecated:
+  - `EnumTrait` - use native PHP 8.1 enums instead
+- The following classes have been added:
+  - `LegacyEnumShimTrait` - can be `use`d by native PHP 8.1 enums to provide the same API as `EnumTrait`
+
+## Gameplay
+### Blocks
+- Implemented the following blocks:
+  - Amethyst
+  - Amethyst Cluster
+  - Chiseled Bookshelf
+  - Crimson Roots
+  - Pitcher Crop
+  - Pitcher Plant
+  - Torchflower
+  - Torchflower Crop
+  - Warped Roots
+
+### Items
+- Implemented the following items:
+  - Pitcher Pod
+  - Torchflower Seeds
+
+## Internals
+- `Farmland` block now has an extra property (`waterPositionIndex`) stored in its blockstate ID to track the position of nearby water. This property is not saved to disk, and is only used for caching.
+- The format of internal blockstate ID has been updated.
+  - The lower `11` bits are now reserved for state data (previously `8` bits). This increase facilitates the new cache for `Farmland` blocks.
+  - The state data bits are now XOR'd with the `xxh3` of the block's type ID, instead of being directly XOR'd with the type ID.
+    - This XOR improves the distribution of the lower bits of the blockstate ID, which is important for hashtable indexing to minimize collisions.
+    - Previously, the lower bits were XOR'd with the type ID directly, but the effectiveness of this reduced as more state data bits were added.
+    - `xxh3` produces consistently good results for this purpose regardless of the number of state data bits allocated.
+    - Hash collisions with blockstate IDs are reduced by 50% with this change, which is a happy side effect.
+  - This is backwards-incompatible, so anyone saving internal blockstate IDs on disk or in a DB will be burned by this change (though they shouldn't have been doing that anyway).
+- Removed code generation step for `RuntimeDataDescriber` enum serialization. All described enums now use PHP 8.1 native enums, which can be described without codegen using `RuntimeDataDescriber->enum()`.
+- Added `DeprecatedLegacyEnumAccessRule` custom PHPStan rule to flag legacy `EnumTrait` case accessors.
+- Cleaned up remaining hardcoded `Config` keys in `SetupWizard`. These usages now use auto-generated constants like the rest of the codebase.
+
+# 5.8.2
+Released 9th November 2023.
+
+## Performance
+- Improved performance of small packet zero-compression (unintended use of slow zlib compressor instead of fast libdeflate one).
+  - This affected the majority of outbound packets, as most packets are below the 256-byte threshold for compression.
+  - This faster method is over 20x faster than the old method, producing noticeable performance gains for large servers.
+
+## Fixes
+- Fixed melons and pumpkins not growing.
+- Fixed melon and pumpkin stems not attaching to the grown melon/pumpkin.
+- Fixed iron and gold ores not being affected by the Fortune enchantment.
+- Fixed ancient debris burning in lava.
+- Fixed sign (front) text loading from vanilla world saves (back text is not yet supported).
+
+## Internals
+- Removed bogus optimization from `tools/generate-blockstate-upgrade-schema.php` that could cause incorrect `remappedStates` generation when some of the states stayed under the old ID.
+- Fixed possible crash in `BlockStateUpgrader` name flattening rule handling with invalid blockstate NBT data.
