+# 4.10.2
+Released 25th November 2022.
+
+## Fixes
+- Fixed crashes on macOS and Linux when using console colours without the `TERM` environment variable set.
+- Fixed crashdumps not being generated when error messages contained invalid UTF-8 characters.
+
+## Documentation
+- Clarified documentation of caching behaviour for `Internet::getIP()`.
+- Added and improved documentation for many `Inventory` methods.
+- Rewritten documentation for `PlayerCreationEvent` with warnings and more detail.
+
+## Internals
+- Non-arrow projectile damage is now unscaled. Scaling according to velocity is only applied to arrows. This currently doesn't cause any observable change in behaviour, but is required for future additions.

+**For Minecraft: Bedrock Edition 1.19.40**
+
+This is a minor feature release for PocketMine-MP, introducing some new features and improvements.
+
+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 4.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.
+
+# 4.11.0-BETA1
+Released 7th November 2022.
+
+## General
+- Packet receive timings have now been split into two subcategories - Decode and Handle.
+- Console command entry can now be disabled via the `console.enable-input` setting in `pocketmine.yml`.
+    - Best suited for headless servers (e.g. in a Docker container) where the console will never be used anyway.
+    - Disabling the console reader slightly reduces memory usage, because console reading currently requires an additional subprocess.
+- Console command output now appears on the terminal only, and is not written to the log file.
+- The output from console commands now appears with a `Command output |` prefix, instead of as a log message.
+- Introduced validation for the `--data` and `--plugins` command line options.
+- Encrypted resource packs are now supported, by means of adding a `.key` file alongside the pack in the `resource_packs` folder.
+    - e.g. `MyEncryptedPack.zip` -> `MyEncryptedPack.zip.key`
+
+## Gameplay
+- Fixed supporting blocks of dead bush to be in line with vanilla.
+- Sugarcane can now be grown using bonemeal on any part of the sugarcane. Previously, it only worked when used on the bottom block.
+- Fixed modifier values for Instant Damage and Regeneration effects.
+
+## API
+### General
+- Plugins are now always disabled before their dependencies, to ensure that they are able to shutdown properly (e.g. a core plugin depending on a database plugin may want to save data to a DB during `onDisable()`).
+- [`webmozart/path-util`](https://packagist.org/packages/webmozart/path-util) has been deprecated, and will be dropped in favour of [`symfony/filesystem`](https://packagist.org/packages/symfony/filesystem) in PM5.
+    - To prepare for this change, simply replace any usage of `Webmozart\PathUtil\Path` with `Symfony\Component\Filesystem\Path`, which is available as a dependency in this release.
+
+### `pocketmine`
+- The following API methods are now deprecated:
+    - `Server->getPlayerByPrefix()`
+
+### `pocketmine\entity`
+- `EntitySpawnEvent` and `ItemSpawnEvent` are now fired on the first tick after the entity is added to the world. Previously, these events were called directly from the entity constructor, making it impossible to get properties like velocity which are often set after the entity is created.
+- The following API methods are now deprecated:
+    - `Living->hasLineOfSight()`
+
+### `pocketmine\item`
+- The following new API methods have been added:
+    - `public Armor->clearCustomColor() : $this`
+
+### `pocketmine\inventory\transaction`
+- Introduced a `TransactionBuilder` class. This makes it less of a hassle to build an `InventoryTransaction` server-side, since the regular `Inventory` API methods can be used, rather than having to manually create `SlotChangeAction`s.
+
+### `pocketmine\player`
+- The following new API methods have been added:
+    - `public Player->sendToastNotification(string $title, string $body) : void` - makes a grey box appear at the top of the player's screen containing the specified message
+
+### `pocketmine\utils`
+- The following new API methods have been added:
+    - `public static TextFormat::addBase(string $baseFormat, string $string) : string` - used for coloured log messages, changes the base formatting of a string by inserting the given formatting codes after every RESET code
+
+## Internals
+- Improved performance of `ContainerTrait` dropping items on block destroy. (24e72ec109c1442b09558df89b6833cf2f2e0ec7)
+- Avoid repeated calls to `Position->getWorld()` (use local variables). (2940547026db40ce76deb46e992870de3ead79ad)
+- Revamped the way `InventoryManager` handles fake inventory slot mappings for stuff like crafting tables. (e90abecf38d9c57635fa0497514bba7e546a2469)
+- Console polling is now done on the main thread (no longer a performance concern).
+- Console reader subprocess should now automatically die if the server main process is killed, instead of persisting as a zombie.
+- `ConsoleCommandSender` is no longer responsible for relaying broadcast messages to `MainLogger`. A new `BroadcastLoggerForwarder` has been added, which is subscribed to the appropriate server broadcast channels in order to relay messages. This ensures that chat messages and command audit messages are logged.
+- `DelegateInventory` now uses `WeakReference` to track its inventory listener. This allows the delegate to be reused.
+
+# 4.11.0-BETA2
+Released 13th November 2022.
+
+## Configuration
+- The `chunk-ticking.per-tick` setting is now deprecated, and will be removed in a future release.
+  - The functionality of this setting has been removed, since it caused more problems than it solved.
+  - Setting it to zero will still disable chunk ticking (for now), but this should now be done by setting `chunk-ticking.tick-radius` to `0` instead.
+
+## Gameplay
+- Improved chunk random ticking:
+  - Removed the limit on chunks ticked per tick, and its associated config option is no longer respected.
+    - This change significantly improves crop and plant growth with large numbers of players, but may cause higher CPU usage.
+    - This limit was causing a linear decrease in chunk ticking speed with larger numbers of players, leading to worsened gameplay experience.
+  - Every chunk within the configured tick radius of a player will be ticked. Previously, chunks were randomly selected from the radius.
+- Implemented Darkness effect.
+
+## API
+### `pocketmine\world`
+- The following new API methods have been added:
+  - `public World->getChunkTickRadius() : int` - returns the world's simulation radius
+  - `public World->setChunkTickRadius(int $radius) : void` - sets the world's simulation radius
+
+## Internals
+- Non-arrow projectile damage is now unscaled. Scaling according to velocity is only applied to arrows. This currently doesn't cause any observable change in behaviour, but is required for future additions.

+- Improved performance of `ContainerTrait` dropping items on block destroy. ([link](https://github.com/pmmp/PocketMine-MP/commits/24e72ec109c1442b09558df89b6833cf2f2e0ec7))

+- Revamped the way `InventoryManager` handles fake inventory slot mappings for stuff like crafting tables. ([link](https://github.com/pmmp/PocketMine-MP/commit/e90abecf38d9c57635fa0497514bba7e546a2469))
+  - Inventories are now mapped on a per-slot basis. This means that more than one inventory can be mapped to the same window ID, which is necessary for correctly handling "UI" inventories like crafting tables.
+  - `InventoryManager->getWindow(int $windowId) : ?Inventory` is replaced by `locateWindowAndSlot` (see below).
+  - Added `InventoryManager->locateWindowAndSlot(int $windowId, int $netSlotId) : array{Inventory, int}` - accepts a window ID and absolute slot ID, and returns the associated inventory and the slot relative to the inventory's own start (for use with `getItem()` etc.).
+  - Slot offset mapping for "UI" inventories is now handled in `InventoryManager->createComplexSlotMapping()` instead of in `TypeConverter`.
+- Console polling is now done on the main thread (no longer a performance concern). ([link](https://github.com/pmmp/PocketMine-MP/commit/b3f03d7ae645de67a54b7300c09b94eeca16298e))
+- Console reader subprocess should now automatically die if the server main process is killed, instead of persisting as a zombie. ([link](https://github.com/pmmp/PocketMine-MP/commit/2585160ca2c4df5758b8b980331307402ff9f0fb))

+- Folder used for plugins (optionally specified by `--plugins`) is no longer required to be writable.
+- Fixed broken writable check for server data folder (`is_writable()` broken on NFS and similar filesystems).
+- `Filesystem::createLockFile()` exceptions now include more information about why the lock file could not be created.
+- Fixed client-side item predictions not being rolled back when cancelling events such as `PlayerItemUseEvent`.
+
+## Dependencies
+- Updated BedrockProtocol to [17.1.0](https://github.com/pmmp/BedrockProtocol/releases/tag/17.1.0+bedrock-1.19.50). This adds some missing `LevelSoundEvent` constants and fixes the values for `ContainerUIIds`.
+
+# 4.12.3
+Released 28th December 2022.
+
+## Fixes
+- Fixed unauthenticated connections taking up player count slots, preventing players from joining.
+- Fixed a possible crash in `World->tickChunk()` when plugins unload chunks during some events.
+- `/gamemode` will now report a failure to change game mode if the player is already in the requested game mode.
+
+# 4.12.4
+Released 3rd January 2023.
+
+## Fixes
+- Added workarounds for an active exploit being used to deny service to servers.
+
+# 4.12.5
+Released 6th January 2023.
+
+## Fixes
+- Removed a workaround for an old client bug in custom form responses. The code contained a denial-of-service vulnerability.
+
+# 4.12.6
+Released 7th January 2023.
+
+## Changes
+- Added a new security measure to `NetworkSession` to detect and ban players who flood the server with packets.
+
+# 4.12.7
+Released 8th January 2023.
+
+## Fixes
+- Fixed players getting kicked when the server lags for too long.
+- Fixed players getting kicked when a debugging session is active and a breakpoint is hit.
+
+# 4.12.8
+Released 9th January 2023.
+
+## Fixes
+- Fixed players getting kicked during PvP.
+- Fixed players randomly getting kicked on Windows (improper rate limit handling wrt. 15ms timer resolution).
+
+# 4.12.9
+Released 16th January 2023.
+
+## Improvements
+### Timings
+- Added new timers:
+  - `Server Mid-Tick Processing` - time spent processing Snooze interrupts between ticks (e.g. incoming network packets)
+  - `Server Tick Update Cycle` - time spent processing regular per-tick updates (e.g. entity movement, world updates, etc.) (`Server->tick()`)
+- `Full Server Tick` timer now counts the total of `Server Mid-Tick Processing` and `Server Tick Update Cycle`, which generates more accurate performance metrics.
+  - Previously, this timer only counted the time spent during regular per-tick updates, and the time recorded by `Server Mid-Tick Processing` was not included in the report at all.
+
+## Fixes
+- Fixed blocks such as pressure plates being able to be placed without the correct supporting blocks if the clicked block was solid.
+- Pressure plates now self-destruct when the block below them is removed.
+- Fixed being unable to place blocks by clicking on the side of a bell (when the click doesn't result in ringing the bell).
+- Fixed various rotation-aware blocks (e.g. stairs) behaving incorrectly when placed by clicking on the side of a replaceable block (e.g. tall grass).
+- Fixed banners being able to be placed on top of blocks such as skulls.
+- Fixed server-side collision boxes of walls and glass (which should connect, but didn't). Note that wall connections still don't show client side - this just fixes the collision boxes.
+- Fixed `PlayerInteractEvent` with `LEFT_CLICK` sometimes firing before `BlockBreakEvent` when breaking blocks.
+
+## Other changes
+- Increased packet batch budget for player sessions.
+
+# 4.12.10
+Released 18th January 2023.
+
+## Fixes
+- Fixed reported server load not including the time spent processing Snooze interrupts between ticks (e.g. incoming network packets).
+- Fixed `Connection Handler` entry in timings report not including time spent receiving packets.
+
+## Note about server load & performance
+This version will report higher apparent server load than previous versions. The actual performance of the server is unchanged; the previous reported load was inaccurate.
+These bugs have been present for nearly 5 years (ever since the first introduction of Snooze in 3.0.0).

+**For Minecraft: Bedrock Edition 1.19.50**
+
+This is a minor feature release for PocketMine-MP, introducing some new features and improvements.
+
+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 4.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.
+
+# 4.13.0-BETA1
+Released 18th January 2023.
+
+## Gameplay
+- Death message is now shown on the death screen when a player dies.
+- Armour damage is now only increased if the armour reduced the damage taken.
+- Implemented Swift Sneak enchantment.
+- Fixed incorrect collision box calculation of walls and glass/bars when connected. Note: Client-side, wall connections are still broken; this only fixes projectile flight server-side.
+
+## Performance
+- Improved performance of chunk selection for chunk random ticking using a cache. This improves performance of chunk random ticking by 10-20%.
+
+## Localization
+- Added localized description for the `/dumpmemory` command.
+
+## Permissions
+- Added the following new core permissions:
+  - `pocketmine.command.effect.other` - allows the player to use the `/effect` command on other players (default operator only)
+  - `pocketmine.command.effect.self` - allows the player to use the `/effect` command on themselves (default operator only)
+  - `pocketmine.command.enchant.other` - allows the player to use the `/enchant` command on other players (default operator only)
+  - `pocketmine.command.enchant.self` - allows the player to use the `/enchant` command on themselves (default operator only)
+  - `pocketmine.command.gamemode.other` - allows the player to use the `/gamemode` command on other players (default operator only)
+  - `pocketmine.command.gamemode.self` - allows the player to use the `/gamemode` command on themselves (default operator only)
+  - `pocketmine.command.give.other` - allows the player to use the `/give` command on other players (default operator only)
+  - `pocketmine.command.give.self` - allows the player to use the `/give` command on themselves (default operator only)
+  - `pocketmine.command.spawnpoint.other` - allows the player to use the `/spawnpoint` command on other players (default operator only)
+  - `pocketmine.command.spawnpoint.self` - allows the player to use the `/spawnpoint` command on themselves (default operator only)
+  - `pocketmine.command.teleport.other` - allows the player to use the `/teleport` command on other players (default operator only)
+  - `pocketmine.command.teleport.self` - allows the player to use the `/teleport` command on themselves (default operator only)
+  - `pocketmine.command.title.other` - allows the player to use the `/title` command on other players (default operator only)
+  - `pocketmine.command.title.self` - allows the player to use the `/title` command on themselves (default operator only)
+
+## Internals
+- Decoupled `Player->sendMessage()` and `Player->sendTranslation()`.
+- Refactored resource pack loading in `ResourcePackManager` to make it easier to understand.
+- Client-aware translation processing has been moved to `NetworkSession` due to being client-specific.
+- Replaced hardcoded strings with constants in various places.
+- `NetworkSession` destructive cleanup is now deferred to the next session tick. This fixes various `InventoryManager` crashes when kicking players during events.
+- Updated code using `strpos()` to use `str_starts_with()`, `str_ends_with()` and `str_contains()` where appropriate.
+- Added documentation for some internal methods.
+
+## API
+### `pocketmine\command`
+- The following new API methods have been added:
+  - `protected VanillaCommand->fetchPermittedPlayerTarget(...) : ?Player` - fetches a player target according to the given sender permissions, or null if not found or not permitted
+
+### `pocketmine\entity`
+- The following new API methods have been added:
+  - `public Living->getDisplayName() : string` - the name of the entity to be shown in death messages, commands etc.
+
+### `pocketmine\event\world`
+- The following new classes have been added:
+  - `WorldSoundEvent` - called when a sound is played in a world
+  - `WorldParticleEvent` - called when a particle is spawned in a world
+
+### `pocketmine\item`
+- The following new API methods have been added:
+  - `public Item->onInteractEntity(Player $player, Entity $entity, Vector3 $clickVector) : bool` - called when a player interacts with an entity with this item in hand
+
+### `pocketmine\lang`
+- `Language->translate()` and `Language->translateString()` no longer parse nested translation in the "base text". This was never intended behaviour, and didn't work beyond the first level anyway.
+
+### `pocketmine\player`
+- The following new interfaces have been added:
+  - `PlayerDataProvider` - implemented by classes which want to offer storage for player data
+- The following new classes have been added:
+  - `DatFilePlayerDataProvider` - the default player data provider, which stores `.dat` files in the `players` folder
+  - `PlayerDataLoadException` - thrown when an error occurs while loading player data
+  - `PlayerDataSaveException` - thrown when an error occurs while saving player data
+- The following API methods have been deprecated:
+  - `Player->sendTranslation()` - use `Player->sendMessage()` instead with a `Translatable` message
+
+### `pocketmine\resourcepacks`
+- The following new API methods have been added:
+  - `public ResourcePackManager->setResourceStack(list<ResourcePack> $resourceStack) : void` - sets the list of resource packs to be applied by players
+  - `public ResourcePackManager->setPackEncryptionKey(string $id, ?string $key) : void` - sets the encryption key to be used for a resource pack
+
+### `pocketmine\utils`
+- The following new API methods have been added:
+  - `public static Filesystem::fileGetContents(...) : string` - a wrapper around `file_get_contents()` which throws an exception on failure
+
+### `pocketmine\world`
+- The following new API methods have been added:
+  - `public World->requestSafeSpawn(?Vector3 $spawn = null) : Promise<Position>` - an async version of `getSafeSpawn()` which generates all the needed chunks before returning
