+**For Minecraft: Bedrock Edition 1.19.40**
+
+### 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.
+
+# 4.10.0
+Released 26th October 2022.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.19.40.
+- Removed support for older versions.
+
+## Fixes
+- Fixed incorrect command descriptions showing in `/help` when multiple commands use the same name. Previously, the most recently registered command would show, even though it wouldn't actually be invoked.
+- Fixed splash potions affecting players in spectator mode.
+- Fixed `World->addParticle()` sending particles to players who couldn't possibly see them when a list of targets was used.
+- Fixed `World->addSound()` sending sounds to players who couldn't possibly hear them when a list of targets was used.
+
+## Documentation
+- Improved type information available for various API methods in `World`.
+
+# 4.10.1
+Released 7th November 2022.
+
+## Fixes
+- Fixed spawning in the void if spawn terrain in a world is solid at the default spawn position.
+- Fixed totems of undying activating when the player has 1 HP remaining.
+- Fixed durable items such as tools becoming unbreakable when in stacks larger than 1. Now, the durability correctly resets when the tool breaks.
+- TPS below 12 now correctly shows as red in `/status`. Previously, it showed as orange due to a condition ordering bug.
+- Improved handling of missing arguments in user-defined `pocketmine.yml` command aliases. Previously, missing arguments would be filled with an empty string, which caused a variety of unexpected behaviour.
+
+## Internals
+- Added validation for the array given to `BaseInventory->setContents()` to ensure that it contains only `Item` instances.
+- Silenced `PlayerAuthInputPacket` spam when the session is in the "spawn response" state.
+- Updated to PHPStan 1.9.
+
+# 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.

+
+# 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.

+- The following new classes have been added:
+  - `BlockDeathEvent` - event called when coral or coral blocks die due to lack of water
+
+### `pocketmine\item`
+- The following new API methods have been added:

+- The following new classes have been added:

+
+## Internals
+- Improved performance of `ContainerTrait` dropping items on block destroy. ([link](https://github.com/pmmp/PocketMine-MP/commits/24e72ec109c1442b09558df89b6833cf2f2e0ec7))
+- Avoid repeated calls to `Position->getWorld()` (use local variables). ([link](https://github.com/pmmp/PocketMine-MP/commit/2940547026db40ce76deb46e992870de3ead79ad))
+- 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))
+- `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. ([link](https://github.com/pmmp/PocketMine-MP/commit/83e5b0adb6fa0dddec377182bb1c7945ac8f7820))

+- 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.
