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

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

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

+
+# 3.3.0
+- Compatibility with Minecraft: Bedrock Edition 1.7.0
+- Removed compatibility with 1.6.0
+- `Player->sendForm()` now throws a proper exception when failing to JSON-encode `Form` objects given to it.
+- Fixed crash when handling later packets in a batch when an earlier packet triggered termination of the player's connection.
+- Fixed a race condition causing progress updates in `AsyncTasks` to be lost when published near completion.
+- Fixed bad decoding for some packets with unsupported structures.
+- Crash dumps no longer report 20 empty lines when an error occurs in `eval()`'d code.
+- `pocketmine/nbt` dependency updated to `0.2.2` to fix bugs (see NBT repo for changelog).
+
+# 3.3.1
+- Chunk ticking no longer occurs in chunks which have an adjacent unloaded chunks, fixing things like grass ticking triggering unintentional chunk loading.
+- Fixed some lighting propagation issues where step count is the same but light level is different.
+- Fixed full-chunk light repopulation producing broken lighting when the generator hasn't been registered on a worker.
+- Fixed a missing field in `MoveEntityDeltaPacket`.
+- Added client-sided rate limiting for crashdump reporting to mitigate involuntary DDoS of the crash archive.
+- Fixed a bug in `start.cmd` where quotes would appear around the "couldn't find installation" message.
+
+# 3.3.2
+- Added a network-layer check for item NBT size to avoid unexplained client-sided crashes due to length overflow.
+- Fixed some desync bugs with double chests when one half of a double chest is unloaded.
+- Anonymous class timings will now have a cleaned path for the identifier relative to the plugins directory.
+- Anonymous class timings now render correctly on timings.pmmp.io.
+- Fixed empty garbage subchunks not getting removed from long-life chunks.
+- `start.ps1`, `start.sh` and `start.cmd` no longer recognize source-code installations. Since source-code installations should only be used by developers who know what they are doing anyway, this was considered unwise to keep.

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

+
+# 3.5.0
+- Compatibility with Minecraft: Bedrock Edition 1.8.0

+
+# 3.5.1
+- Fixed internal server errors when attempting to craft.

+- Fixed `Utils::getCoreCount()` crashing on some Debian variants.
+
+# 3.5.3
+- Rewritten documentation of `PlayerPreLoginEvent`, `PlayerLoginEvent` and `PlayerJoinEvent`. They are now much more detailed and no longer misleading.
+- Chest items block-picked from double chests will no longer place chests that crash the server when opened.
+- Ender chests now make the correct sounds when opening and closing.
+- Fixed Sign errors when a buggy or malicious client sent broken NBT with the wrong tags or wrong number of lines.
+- Resource packs with comments in the manifest will now load correctly. (MOJANG!!!)
+- Placement of unknown blocks is now disallowed. This solves a range of problems with invalid blocks in the world, such as #2260 .
+- Errors thrown during `PlayerQuitEvent` or other `Player->close()` errors will now crash the server instead of causing cryptic bugs later on.
+- Fixed large chunks (>= 1044476 bytes) becoming corrupted when saved in Region-based worlds - now an exception is thrown instead.
+- Reduced the range of exceptions caught during chunk loading. Now, only chunk corruption errors are caught, and anything else will produce a crash.
+- Removed catch-all block on chunk saving. Unexpected errors thrown during chunk save will now create a crash.
+- Fixed some asserts in packet decode methods.
+- `Attribute` now throws exceptions with more informative messages on errors.
+- Properly handled some remaining `Uninitialized string offset` bugs when decoding packets.
+- Fixed chunk updates taking several seconds to show up on the client. This bug was most apparent during generation and some world editing tools using asynchronous tasks.
+- Fixed CPU waste ordering chunks for non-moving players.
+
+# 3.5.4
+### Fixes
+- Fixed server crash when a block update occurs on a torch with corrupted metadata.
+- Added a hack to mitigate client-side right-click spam bug. This mostly eliminates spam of `PlayerInteractEvent` on right-click.
+- Players will no longer see commands they don't have permission to use in client-sided hints when typing a `/` in the chat window.
+- `Event->isCancelled()` and `Event->setCancelled()` now throw more informative errors.
+- Errors thrown during a network interface processing will now _actually_ crash the server.
+
+### API changes

+- Deprecated `Network->processInterface()`
+- Deprecated `SourceInterface->emergencyShutdown()`
+
+# 3.5.5
+- Mobs no longer spawn with their heads facing a different direction to their bodies.
+- Added a console message when the crash strangler sleeps to stop crash spam.
+- Fixed crash in `/title` command `times` subcommand when not enough arguments were passed.
+- AsyncWorkers will now not be shut down on GC unless they have not been used for the last 5 minutes. This reduces lag spikes on garbage collection.
+- Fixed some unhandled error cases in `AddEntityPacket` encoding.
+- Fixed `LogicException` descendents being thrown from some packet decoding methods when encountering bad userdata.
+- Player network inventory transaction processing now catches more specific errors.
+- Fixed missing decode for `TakeItemEntityPacket`.
+- Fixed `/gc` and `/status` truncating memory statistics - now they report to 0.01 precision.
+- Global functions and constants are now imported to improve performance.
+- Fixed a typo in `pocketmine.command.op.take` description.
+- Ice no longer creates water when a creative player breaks it.
+- `spawn-mobs` and `spawn-animals` no longer appear in generated `server.properties` on a newly-installed server.
+- Added a hack to disable pre-spawn client-sided movement.
+- Assertions enabled warning now always shows when `zend.assertions` is not `-1`. The config option to disable this warning has been removed.
+- `/status`,`/dumpmemory` and `/gc` are now enabled by default. The `debug.commands` config option has been removed.
+- Crash dumps are now more thorough at catching plugin-related crashes.
+
+# 3.5.6
+- Fixed `#`-commenting properties in `.properties` files not working.
+- `pocketmine.yml` now permits writing `worldname:` with no generation settings in the `worlds` section to force a world to be loaded.
+- Fixed Bow force being too low - now it's consistent with Minecraft Java (but not with Bedrock due to a vanilla bug).
+- Fixed `recursion detected` bug when encoding crashdumps in some cases.
+- Items with too-large NBT tags on network will now have their tags ignored when sending over network, instead of crashing the server. This is a workaround for a protocol bug which will be addressed in a future Minecraft release.
+- `/enchant` no longer crashes the server when out-of-bounds enchantment levels are used.
+- Fixed some crashes loading Region-based worlds when encountering unexpected EOF.
+- `Entity->fireTicks` is now protected (but accessible by magic method for BC purposes) and will now throw an exception when written to if the value is > 32767 or < 0.
+- Fixed Signs asserting on corrupted world data with more than 4 lines of text per sign.
+
+# 3.5.7
+- Fixed several bugs in RCON packet receive that would allow an attacker to block or crash the RCON thread, denying service to other legitimate RCON clients.
+- Fixed RCON connections not working (timing out with no response) on some platforms.
+- Logins are now permitted to have up to 60 seconds clock drift on the `nbf` and `exp` timestamps in the login JWT.
+- Fixed XP orbs following players who switched to a location spatially nearby in a different world.
+- `Player->removeWindow()` now throws `InvalidArgumentException` instead of `BadMethodCallException` when trying to non-forcefully remove a fixed window ID.
+
+# 3.5.8
+- Fixed player XP not dropping if a player was fast enough to respawn.

+- Explosions no longer create broken double chests which crash the server. Existing chests affected by this bug will continue to crash. This will be addressed in a future release.
+- Cactus and sugarcane no longer grow through non-air blocks.
+- Fixed a memory leak in `setChunk()` when the `unload` parameter is true.
+- Generator will now crash if preset is invalid, instead of producing unexpected results.

+
+# 3.5.12
+- Fixed crash when too-large values are given to `/effect` for duration.
+- `/op` and other commands no longer crash when an invalid player name is given.
+- Startup time no longer includes the time spent in the setup wizard.
+- `TextFormat::clean()` is now UTF-8 aware, and will scrub any invalid UTF-8 characters from the given string.
+- Fixed `TextFormat::clean()` not fully removing ANSI escape codes in some cases.
+- Fixed Korean command arguments failing to parse.
+- `Sign->setText()` and `Sign->setLine()` now enforce that the given text must be UTF-8 text, or an exception will be thrown.
+- Sign text is now processed by `mb_scrub()` immediately after loading to remove invalid UTF-8 characters that could crash the client.
+- `Human->exhaust()` no longer underflows when the hunger attribute has a fractional value.
+
+# 3.5.13
+- Added a hack to disable client sided AI for non-moving entities. This fixes items floating in water despite it not being implemented server-side yet.
+- Fixed max health not working as expected on respawn if changed by plugins.
