+**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 classes have been added:
+  - `Lectern`
+  - `Pumpkin`
+- The following public API methods have been added:
+  - `Block->getTypeId() : int` - returns an integer which uniquely identifies the block type, ignoring things like facing, colour etc.
+  - `VanillaBlocks::LECTERN()`
+
+### Entity
+- The following classes have been added:
+  - `animation\ItemEntityStackSizeChangeAnimation`
+- The following public API methods have been added:
+  - `object\ItemEntity->isMergeable(object\ItemEntity $other) : bool`
+  - `object\ItemEntity->setStackSize(int $size) : void`
+  - `object\ItemEntity->tryMergeInto(object\ItemEntity $other) : bool`
+  - `ExperienceManager->canAttractXpOrbs() : bool`
+  - `ExperienceManager->setCanAttractXpOrbs(bool $v = true) : void`
+  - `Entity->getSize() : EntitySizeInfo`
+  - `Living->isGliding() : bool`
+  - `Living->isSwimming() : bool`
+  - `Living->setGliding(bool $value = true) : void`
+  - `Living->setSwimming(bool $value = true) : void`
+- 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:
+  - `BlockMeltEvent` - called when ice or snow melts
+  - `ChestPairEvent` - called when two chests try to form a pair
+  - `PlayerToggleGlideEvent` - called when a player starts or stops gliding
+  - `PlayerToggleSwimEvent` - called when a player starts or stops swimming
+
+### Item
+- The following public API methods have been added:
+  - `SplashPotion->getType() : PotionType`
+  - `VanillaItems::AIR()`
+- The following API methods have been deprecated:
+  - `ItemFactory::air()` - use `VanillaItems::AIR()` instead
+
+### 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:
+  - `Server::DEFAULT_SERVER_NAME`
+  - `Server::DEFAULT_MAX_PLAYERS`
+  - `Server::DEFAULT_PORT_IPV4`

+- Added `TextFormat::MINECOIN_GOLD`, and support for it to the various `TextFormat` methods.
+- 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.

+**For Minecraft: Bedrock Edition 1.18.10**
+
+### 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.
+
+# 4.2.0
+- Added support for Minecraft: Bedrock Edition 1.18.10.
+
+# 4.2.1
+Released 19th February 2022.
+
+## General
+- Improved performance of `Item::nbtSerialize()` - this will improve performance during world saves.
+- Added more missing changes to the 4.0.0 changelog.
+
+## Fixes
+- Fixed multiple players being able to sleep in the same bed.
+- Fixed hitbox not resetting properly after swimming or gliding.
+
+# 4.2.2
+Released 2nd March 2022.
+
+## Fixes
+- Fixed crash in `/dumpmemory` due to usage of non-printable string keys in `CraftingManager`. Array contents in memory dumps are now rendered as prettified key-value pairs.
+- Fixed output directory for `/dumpmemory`.
+- `PlayerInventory->isHotbarSlot()` now correctly returns `false` when given `9`.
+- Fixed ghost items left in the inventory when dropping tools while mining.
+
+# 4.2.3
+Released 9th March 2022.
+
+## Technical
+- Now analysed using PHPStan 1.4.8.
+- Now using `pocketmine/bedrock-protocol` [`8.0.1`](https://github.com/pmmp/BedrockProtocol/releases/tag/8.0.1%2Bbedrock-1.18.10).
+
+## Fixes
+### Core
+- Fixed a memory leak and other bugs related to plugins disabling themselves during `onEnable()`.
+
+### Gameplay
+- Sweet berry bushes now absorb fall damage.
+- Fixed mycelium spreading onto coarse dirt.
+- Fixed blocks placed during `Block->onIncinerate()` getting overwritten.
+- Fixed shulker boxes being unopenable when underwater.
+- Fixed invisible fire on top of transparent non-flammable blocks.
+
+### API
+- Various APIs accepting `Vector3`, `Position` or `Location` no longer accept objects containing `INF` or `NaN` in any component. Previously, this was allowed, but would cause lots of obscure crashes later on.
+- `Entity->setRotation()` no longer accepts `INF` or `NaN`.
+- Fixed missing bounds check for `ItemFrame->setItemDropChance()`.
+
+# 4.2.4
+Released 18th March 2022.
+
+## Fixes
+- Fixed a crash when handling out-of-bounds meta values on the network.
+
+# 4.2.5
+Released 28th March 2022.
+
+## General
+- The layout of the human-readable part of crashdumps has been changed in an effort to improve the useful information density. It is hoped that this change will cause more useful information to be provided when people paste crash traces on Discord, since all the most important information is now at the top of the file.
+  - Version, git hash, PHP version and OS have been moved to the top of the crashdump.
+  - Backtrace has been moved above code sample.
+- Docker images are now built by GitHub Actions (first live test).
+
+## Technical
+- The methods of `Inventory` and `BaseInventory` have been rearranged to improve coherency.
+
+## Fixes
+### API
+- Enum members of enums created using `EnumTrait` are now able to have single-character names.
+- Registry members of registries created using `RegistryTrait` or `CloningRegistryTrait` now have their names checked for invalid characters.
+- `Entity::__construct()` now uses a guard variable to prevent it from being called multiple times unintentionally. This is necessary because `Entity::__construct()` has side effects.
+- Fixed `PlayerItemHeldEvent` not being called when the content of the held slot was changed (e.g. replacing the held item via inventory menu).
+
+### Gameplay
+- Reduced the appearance of ghost items in unsupported gameplay scenarios using client prediction information. This fixes, for example, the appearance of ghost items when right-clicking on a filled flower pot.
+
+# 4.2.6
+Released 1st April 2022.
+
+## Fixes
+- Fixed buffer length underflow crash in `LoginPacket` handling.
+
+# 4.2.7
+Released 15th April 2022.
+
+## General
+- Added lots more documentation (in comments) about the `aliases` section in `pocketmine.yml`. You can read about this feature in the `aliases` section of the [updated `pocketmine.yml` template](/resources/pocketmine.yml).
+- Improved wording of documentation of `PlayerPreLoginEvent`.
+
+## Fixes
+- Fixed core server crash when a plugin causes another plugin to be disabled during a scheduled task.
+- Fixed core server crash when loading a plugin with an abstract main class.
+- Fixed ghost items in many interaction situations (most notably, using projectiles while looking at an entity or block).
+- Implemented a workaround for a client teleport bug which led to player positions not updating properly when using ender pearls.
+- Fixed buggy movement when teleporting the player during `PlayerToggleSneakEvent`, `PlayerToggleSprintEvent`, `PlayerToggleSwimEvent` and `PlayerToggleGlideEvent`.
+
+# 4.2.8
+Released 17th April 2022.
+
+## Fixes
+- Fixed a memory leak in RakLib which could result in a server crash when players stay online for a long time.
+- Fixed server crash when attempting to load a corrupted empty resource pack.
+- Fixed users with the same name with differerently cased letters being able to duplicate items (userdata is matched by case-insensitive name).
+
+# 4.2.9
+Released 19th April 2022.
+
+## Fixes
+- Fixed several potential crashes when deserializing item NBT (due to insufficient validation of input data).
+
+# 4.2.10
+Released 20th April 2022.
+
+## Fixes
+- Fixed performance issue when chat messages received from the client contain many newlines. This security vulnerability was disclosed publicly necessitating a priority fix.
