+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.

+  - Encryption is enabled by default.
+  - Fixes login replay attacks.

 ### Misc
 - Added support for emotes.
+
+# 4.0.1
+Released 9th December 2021.
+
+## General
+- Added a script `tools/ping-server.php`. This was sitting in my workspace for many years.
+- `Minecraft network interface running` messages are no longer shown if RakLib was prevented from starting.
+
+## Fixes
+### Core
+- Fixed server crash when `FallingBlock` has invalid block data that it can't understand.
+- Fixed server crash when loading chunks containing tiles outside the world bounds.
+- Fixed server crash when loading LevelDB chunks containing blockstates which are invalid or not yet supported - they are now treated as corrupted instead.
+- Fixed `level.dat` becoming corrupted by world saves when the disk is full - now it will still fail to save, but it will leave the original data intact. Previously it would destroy the data and leave behind an empty file.
+- Fixed configs becoming corrupted when saved when the disk is full - now they'll still fail to save, but the original file will remain intact.
+
+### API
+- Fixed mistakes in the 4.0.0 changelog:
+  - Removal of `Player->getLowerCaseName()` is now mentioned.
+  - `CreativeInventory::reset()` is the successor to `Item::initCreativeItems()`, not `CreativeInventory::init()`.
+  - Note that the changelog when viewing from the 4.0.0 GitHub release will remain the same; only the changelog in the current repo will be different.
+- `Config->save()` will no longer write empty data to the file when using JSON and the data fails to encode - an exception will be thrown instead.
+- `StringToItemParser` now returns the correct items for `bamboo`, `shulker_box`, `stone_slab`, `stone_stairs` and `tall_grass`.
+- `StringToItemParser` now recognizes `slime` and `slime_block` (these were previously missing).
+
+# 4.0.2
+Released 12th December 2021.
+
+## Fixes
+### Core
+- Fixed server crash when loading written books containing pages with invalid UTF-8 characters - the invalid characters are now scrubbed.
+- Fixed server crash when root type of `plugin.yml` is valid, but not an array.
+- Fixed ConsoleReader crash due OPcache ASLR issue - it's not clear what caused this, but OPcache is not needed in the subprocess anyway.
+- Fixed backslashes getting stripped from unquoted command arguments - these were only supposed to be stripped from quoted arguments, to allow escaping of quotes.
+- `build/generate-known-translation-apis.php` now sorts numerically-indexed arguments into ascending order, irrespective of the order they appear in the original string.
+
+### API
+- `KnownTranslationKeys` and `KnownTranslationFactory` are now marked `@internal`.
+- `ItemEntity` now clones the itemstack passed to its constructor, fixing various confusing mutability issues.
+- `PlayerExperienceChangeEvent->setNewProgress()` now performs range checks. This fixes the root of a very old and confusing crash bug which took several years to identify the cause of.
+  - Note that the defective plugin(s) which caused this problem will still cause a server crash, but the plugin responsible will now get blamed correctly.
+- `GeneratorManager->addGenerator()` now consistently converts the given alias to lowercase. Due to a bug, it previously didn't do this if the `$overwrite` parameter was set to `true`, causing a range of confusing bugs.
+
+# 4.0.3
+Released 16th December 2021.
+
+## Fixes
+- Fixed `/dumpmemory` crashing when encountering uninitialized typed properties.
+- Fixed all chunks containing furnaces being treated as corrupted in worlds older than 2017.
+  - This was caused by a strict corruption check detecting bad data created by a bug in PocketMine-MP that was fixed in 2017.
+- Fixed player arm swing animation not being shown when attacks were cancelled by attack cooldown.
+- Fixed being unable to use `/deop` to de-op a player whose name appeared in `ops.txt` with uppercase letters in it.
+- Added a check for valid tile class in `BlockIdentifier`.
+
+# 4.0.4
+Released 1st January 2022.
+
+## General
+- Improved performance of loading chests and other containers from world saves.
+- Improved performance of loading player inventories from saved data.
+
+## Fixes
+- Fixed a crash that could occur when a chunk failed to be prepared for chunk sending.
+- Fixed fall damage when sprinting down stairs.
+- Fixed message length limit for chat (now 512 instead of 255, and accounts for UTF-8).
+- Fixed incorrect message being displayed when trying to sleep in a bed which is too far away.
+- Fixed missing space between `Kicked by admin.` and `Reason` when using `/kick` to kick a player.
+- Fixed client-side performance issue of entities with very large scale.
+
+# 4.0.5
+Released 4th January 2022.
+
+## Fixes
+- Fixed several denial-of-service attack vectors related to writable book text length and encoding.
+- Fixed several denial-of-service attack vectors related to skin data field lengths.
+- Fixed food bar desync when cancelling `PlayerItemConsumeEvent` in a plugin.
+- Fixed compass needles not updating when the world spawn is changed.
+
+# 4.0.6
+Released 13th January 2022.
+
+## Fixes
+- Fixed server crash on invalid facing values provided by the client when placing or breaking blocks.
+- Fixed documentation link to AsyncTask in Worker.
+
+# 4.0.7
+Released 21st January 2022.
+
+## General
+- Max nesting of form responses is now limited to 2.
+- Updated outdated documentation of `PlayerInteractEvent`.
+
+## Fixes
+- Fixed server crash on invalid JSON provided by the client in `ModalFormResponsePacket`.
+- Fixed ender pearls teleporting players when thrown by a player directly against a wall when cancelling `ProjectileLaunchEvent`.
+- Fixed collision box of brewing stand.
+- Fixed break times and tool types of bamboo, nether wart blocks, infested stone and leaves.

+# 4.0.8
+Released 25th January 2022.
+
+## Fixes
+- Fixed ender chest not dropping itself when mined with a Silk Touch pickaxe.
+- The correct amount of fall damage is now taken when falling from a height onto hay bales.
+
+# 4.0.9
+Released 5th February 2022.
+
+## Fixes
+### Core
+- The spawn chunk of the default world is no longer loaded during shutdown. Previously, it would attempt to find a safe spawn to teleport players to, only to unload the target world of that safe spawn and not use it.
+- The spawn chunk of the default world is no longer loaded when unloading a non-default world containing zero players.
+- Fixed chunk version `8` in Bedrock worlds being treated as corrupted. These appeared in worlds between 1.2.13 and 1.8.0.
+
+### API
+- Added missing bounds check to `Liquid->setDecay()`.
+- Fixed `StringToItemParser` returning concrete instead of concrete powder when given `<color>_concrete_powder`.
+
+### Gameplay
+- Cobwebs now drop themselves when broken using shears.
+- Fixed spectator players being able to drop items.
+- Fixed collision shapes of Bell in different orientations.

+**For Minecraft: Bedrock Edition 1.18.0**
+
+### 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.
+
+# 4.1.0-BETA1
+Released 22nd January 2022.
+
+## General
+- Game mode names (e.g. `survival`, `creative`) may now be used for the `gamemode` property in `server.properties`.
+- Increased default maximum render distance to 16 chunks. Players with a render distance smaller than this will notice no difference.
+- The setup wizard now prompts for a maximum render distance value.
+- The setup wizard now prompts for an IPv6 port selection. Previously it would always use 19133.
+- `chunk-ticking.disable-block-ticking` now accepts block names like those used in the `/give` command.
+- The `/clear` command now behaves more like vanilla:
+  - The order of inventories is now the same as Bedrock.
+  - The cursor and offhand inventories are now cleared if necessary.
+
+## Technical
+- `PlayerAuthInputPacket` is now used instead of `MovePlayerPacket` for processing movements. This improves position and rotation accuracy.
+- `&&` and `||` are now always used instead of `and` and `or`.
+- New version of `pocketmine/errorhandler` is used by this version, adding support for `ErrorToExceptionHandler::trap()`. This enables reliably capturing `E_WARNING` and `E_NOTICE` from functions such as `yaml_parse()` and friends.
+- New dependency versions are required by this version:
+  - `pocketmine/bedrock-protocol` has been updated from 7.1.0 to [7.3.0](https://github.com/pmmp/BedrockProtocol/releases/tag/7.3.0%2Bbedrock-1.18.0).
+  - `pocketmine/errorhandler` has been updated from 0.3.0 to [0.6.0](https://github.com/pmmp/ErrorHandler/releases/tag/0.6.0).
+
+## API
+### Block

+- The following protected API methods have been added:
+  - `Entity->getBlocksIntersected(float $inset) : \Generator<int, Block, void, void>`
+
+### Event
+- `BlockSpreadEvent` is now called when fire spreads to the positions of blocks it burns away.
+- `BlockFormEvent` is now called when concrete powder turns into concrete due to contact with water.
+- The following classes have been added:

+
+### Player
+- The following public API methods have been added:
+  - `Player->hasBlockCollision() : bool`
+  - `Player->setHasBlockCollision(bool $value)` - allows controlling spectator-like no-clip behaviour without changing game mode
+  - `Player->toggleSwim(bool $swim) : bool` - called by the network system when the client tries to start/stop swimming
+  - `Player->toggleGlide(bool $glide) : bool` - called by the network system when the client tries to start/stop gliding
+
+### Server
+- The following public API constants have been added:

+- The following public API methods have been added:
+  - `Utils::assumeNotFalse()` - static analysis crutch to silence PHPStan errors without using `ignoreErrors` or `@phpstan-ignore-line`, which are both too coarse.
+- The following public API properties have been added:
+  - `Terminal::$COLOR_MINECOIN_GOLD`
+- The following classes have been added:
+  - `ConfigLoadException`
+- Fixed `Random->nextSignedInt()` to actually return a signed int. Previously it would return any integer value between 0 and 4,294,957,295.
+- Fixed `Random->nextSignedFloat()` to return a float between `-1.0` and `1.0`. Previously it would return any value between `0.0` and `2.0`.
+- `VersionString->getNumber()` output is now structured differently to fix overflow issues caused by the old format.
+
+### World
+- The following classes have been added:
+  - `sound\ItemUseOnBlockSound`
+  - `sound\LecternPlaceBookSound`
+
+## Gameplay
+### Blocks
+- Fire now spreads.
+- Implemented lectern blocks.
