+## 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.

+# 3.11.6
+- Core code, tests and build scripts are now analyzed using `phpstan-strict-rules` and `phpstan-phpunit` rules.
+- Added more PHPStan-specific type annotations to improve static analysis.
+- Fixed more incorrect PHPDoc types.
+- Added a workaround for player movement not working since 1.14.30.
+- Fixed lava and water buckets being edible since 1.13.
+- `AutoUpdater` is now created before any plugins are loaded.
+- Fixed trees not generating below y=2 in custom generators.
+- Fixed crash when opening a chest improperly unpaired from its pair (destroyed, setBlock(), unloaded, etc.).
+- `ThreadManager` is now lazily initialized.
+- Removed raw NBT storage from `Item` internals. The following methods are now deprecated:
+  - `Item::setCompoundTag()`

+# 3.11.7
+- Build system: Fixed crash reports of Jenkins builds being rejected by the crash archive as invalid.
+- Introduced a new dependency on `pocketmine/log-pthreads`, which contains classes separated from `pocketmine/log`.
+- Fixed minimum composer stability preventing any newer version of `pocketmine/pocketmine-mp` being installed than 3.3.4 by replacing `daverandom/callback-validator` with [`pocketmine/callback-validator`](https://github.com/pmmp/CallbackValidator).
+- Fixed every player seeing eating particles when any player eats.
+- Fixed setting held item not working during `BlockBreakEvent`, `PlayerInteractEvent` and `EntityDamageEvent`.
+- Fixed some incorrect documented types in `PlayerQuitEvent` reported by PHPStan.
+- Fixed documentation of `Item->pop()` return value.
+- Fixed server crash on encountering corrupted compressed data stored in region files.
+- Protocol: Split screen header is now properly accounted for during decoding. Note that split screen is still not supported natively, but their packets can be decoded properly now.
+- Protocol: Fixed wrong order of fields in `UpdateTradePacket`.

+- 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.
+- `WritableBook->getPageText()` no longer throws an exception when the page doesn't exist, but returns null (as it was originally intended to).
+
+# 3.12.4
+- Fixed absorption hearts not being consumed.
+
+# 3.12.5
+- Fixed broken attack cooldowns.
+
+# 3.12.6
+- Fixed entities not getting movement updates after teleports.
+- Fixed slow flight in spectator mode when starting from the ground and after teleportation.
+- Errors communicating with the crash archive on automatic crash submission are now logged.

+**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.

+### 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.
+
+# 3.14.0
+- Added support for Minecraft: Bedrock Edition 1.16.0.
+- Removed compatibility with 1.14.60.
+
+## Known issues (please don't open issues for these)
+- Walls don't connect to each other
+- Pumpkin and melon stems may not connect to their corresponding pumpkin/melon
+- New blocks, items & mobs aren't implemented
+- Nether doesn't exist
+
+# 3.14.1
+- 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`.

+- Pumpkin and melon stems may not connect to their corresponding pumpkin/melon
+- New blocks, items & mobs aren't implemented
+- Nether doesn't exist
+
+# 3.15.1
+- Fixed various PHP 7.4 compatibility issues in Composer dependencies (primarily callback-validator).
+- Fixed LevelDB worlds with corrupted `level.dat` crashing the server instead of failing gracefully.
+- Fixed error spam when using strings for layers in flatworld presets (`e.g. bedrock,3xdirt,grass`).
+- Fixed blocks not getting updated properly on explosions.
+- Fixed `BlockGrowEvent` not being called when sugarcane grows.
+- Potato crops now drop poisonous potatoes when harvested.
+- Fixed the wrong number of potatoes being dropped when harvesting potato crops.
+- 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.
+
+# 3.15.4
+- Fixed a bug in the inventory transaction system that caused the server to freeze under some circumstances.
