+- **Non-disruptive** means that usage should not be significantly altered by the change.
+  - Examples of **non-disruptive** changes include adding new commands, or gameplay features like blocks and items.
+  - Examples of **disruptive** changes include changing the way the server is run, world format changes (since those require downtime for the user to convert their world).
+- **API** includes all public and protected classes, functions and constants (unless marked as `@internal`).
+  - Private members are not part of the API, **unless in a trait**.

+**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.

+**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))
+- Avoid repeated calls to `Position->getWorld()` (use local variables). ([link](https://github.com/pmmp/PocketMine-MP/commit/2940547026db40ce76deb46e992870de3ead79ad))

+  - 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))

+**For Minecraft: Bedrock Edition 1.19.50**
+
+### 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.
+
+# 4.12.0
+Released 30th November 2022.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.19.50.
+- Removed support for older versions.
+
+# 4.12.1
+Released 4th December 2022.
+
+## Fixes
+- Fixed items glitching when dragging a stack of items across the crafting grid (desync issues).
+
+# 4.12.2
+Released 15th December 2022.
+
+## Fixes
+- 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).
+
+# 4.12.11
+Released 22nd January 2023.
+
+## General
+- Code is now tested and analysed using PHP 8.2 in addition to 8.1 and 8.0.
+
+## Fixes
+- Fixed pthreads 5.0.0 incorrectly being treated as compatible.
+- Fixed deprecation errors on PHP 8.2.
+
+## Documentation
+- Updated documentation in `PlayerPreLoginEvent`.

+
+# 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:

+  - `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

+## 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`

-**For Minecraft: Bedrock Edition 1.19.0**
-
-# 5.0.0-ALPHA1
-Released 6th July 2022.
-
-This is a development snapshot of 5.0.0, an upcoming major update to PocketMine-MP. This version includes many new improvements, including support for Bedrock worlds from 1.13 onwards, a large array of new blocks, and various changes to the plugin API.
-
-## WARNING
-**This is an ALPHA release.** It is an early development snapshot of the upcoming 5.0.0 release.
-This means it is LIKELY to be unstable, and/or have performance issues not found in the latest stable releases.
-
-**BACK UP your data before testing this.** This version will work with worlds and player data from 4.x, **BUT** any world or player data loaded in 5.0.0 **will not work in 4.x** due to backwards-incompatible storage format changes.
-
-In addition, there are a number of breaking API changes. Plugins for 4.x may require code changes to run on this version.
-
-The API is **not finalized**. You should expect further changes in later alphas.
-
-## Core
-- Worlds are now saved according to the Bedrock 1.19.0 format.
-- Worlds generated by Bedrock from 1.13.0 and up are now supported (previously, only worlds up to 1.12 were supported).
-- `/particle` now accepts strings for particle data instead of integers.
-- `/particle` no longer accepts integers for block or item IDs.
-- The usage of `blockcrack`, `iconcrack` and `blockdust` particle types in `/particle` now follows the same pattern as other particle types, with the data for each being passed in the `data` parameter instead of being baked into the particle name.
-
-## Tools
-- The following tool scripts have been added:
-  - `generate-block-palette-spec.php` - generates a JSON file with a readable overview of blocks, their state properties, and their possible values
-  - `generate-blockstate-upgrade-schema.php` - generates JSON blockstate upgrade schemas like those found in [BedrockBlockUpgradeSchema](https://github.com/pmmp/BedrockBlockUpgradeSchema)
-  - `generate-item-upgrade-schema.php` - generates JSON item ID/meta upgrade schemas like those found in [BedrockItemUpgradeSchema](https://github.com/pmmp/BedrockItemUpgradeSchema)

-
-## API
-### General
-- Protected and public properties now use native property types wherever possible.
-- Parameter and return typehints have been applied in many places where it wasn't previously possible.
-
-### `pocketmine\block`
-#### Runtime block representation
-- Blocks no longer use internal Minecraft IDs and metadata to identify themselves. All APIs associated with legacy IDs and meta have been removed.
-- A new set of runtime IDs generated from `VanillaBlocks` is used to identify block types. These IDs are defined in `BlockTypeIds`.
-  - These new IDs are used for runtime representation of blocks on chunks, and for type comparison purposes.
-  - Block type IDs are used at **runtime only**. They should **NOT** be stored in configs or databases, as they are subject to change without warning.
-- Block state properties (e.g. facing, colour, etc.) are now represented by PM-specific state data instead of legacy metadata. The state data consists of:
-  - Dynamic type data - this is retained by items when the block is broken (colour, wet/dry, coral type, etc.) - handled by `Block->decodeType()` and `Block->encodeType()`
-  - State data - this is discarded when the block is broken (facing direction, lit/unlit, powered/unpowered, etc.) - handled by `Block->decodeState()` and `Block->encodeState()`
-
-**Block type IDs, and state/type data, are intended for use at RUNTIME only. The values of type IDs and state data may change without warning. They should NOT be saved in configs or databases.**
-
-#### Implementing new blocks
-To register a new block, the following changes are now required:
-
-- Add a new type ID to `BlockTypeIds`
-- Register the block in `BlockFactory`
-- Amend `VanillaBlocks` to include the new block
-- Amend `BlockStateToBlockObjectDeserializer` to deserialize the block from disk
-- Amend `BlockObjectToBlockStateSerializer` to serialize the block for disk
-- Optionally, amend `StringToItemParser` to add string alias(es) for the block, so that it can be given via `/give`
-
-This is admittedly rather more of a hassle than in the old days, but that's the price of abstraction. Research is underway for ways to improve this without spaghettifying the code again.

-- `Entity` now declares new abstract methods which must be implemented by subclasses:
-  - `public Entity->getInitialDragMultiplier()`
-  - `public Entity->getInitialGravity()`
-
-### `pocketmine\item`
-#### Runtime item representation
-- Items no longer use internal Minecraft string IDs and metadata to identify themselves. All APIs associated with legacy IDs and/or meta have been removed.
-- A new set of runtime item IDs generated from `VanillaItems` is now used to identify item types. These IDs are defined in `ItemTypeIds`.
-  - These new IDs are primarily intended for type comparison purposes.
-  - Item type IDs are used at **runtime only**. They should **NOT** be stored in configs or databases, as they are not guaranteed to remain the same between versions.
-- In some cases, items may have additional "type data" which provides extra type information about an item. This replaces item metadata in some cases.
-  - Type data may be used to store dynamic type information such as dye colour, potion type, etc.
-  - Items must have the same type ID **and** type data in order to be stackable.
-- Blocks, when represented as items:
-  - retain their block type data, but not state data (for example, different colours of concrete don't stack, but things like facing don't affect stackability)
-  - use the negative of their block type ID (e.g. a block with type ID `1` will have an item type ID of `-1`).
-- Durable items (e.g. tools, armour) now use NBT `Damage` tag to store durability (like Minecraft 1.13+), instead of legacy meta values.
-
-**Item type IDs and type data are intended for RUNTIME use only. The values of type IDs and/or type data may change without warning. They should NOT be saved in configs or databases.**
-
-#### Implementing new items
-To register a new item, the following changes are now required:
-
-- Add a new ID to `ItemTypeIds`
-- Register the item in `ItemFactory`
-- Amend `VanillaItems` to add the item
-- Amend `ItemDeserializer` to add a deserializer for loading the item from disk
-- Amend `ItemSerializer` to add a serializer for saving the item to disk
-- Optionally, amend `StringToItemParser` to add string alias(es) for the item, so it can be given via `/give`
-
-Again, it's acknowledged this is rather more cumbersome than it should be, but this is an ongoing process.
-
-#### Change list
-- `Item` is no longer `json_encode()`-able.
-  - The original purpose of this was to allow items to be serialized to JSON for crafting data generated from `CraftingDataPacket`. Due to changes in the generation methodology, bypassing `Item`s entirely, this is no longer necessary.
-  - `jsonSerialize()` requires the item to know about the method by which it will be serialized, creating a cyclic dependency between the `Item` implementation and its serialization method.
-  - It's relatively easy to write a replacement method to encode items to JSON as you desire.
-- The following classes have been removed:
-  - `ItemIds`
-  - `Skull`
-  - `Bed`
-- The following classes have been added:
-  - `CoralFan`
-  - `Spyglass`
-- The following API methods have been added:
-  - `public Dye->setColor()`
-  - `public ItemIdentifer->getTypeId()`
-  - `public static ItemIdentifier::fromBlock()`
-  - `public Potion->setType()`
-  - `public SplashPotion->setType()`
-- The following API methods have been removed:
-  - `Item->getId()` - for type comparisons, use `Item->getTypeId()` instead
-  - `Item->getMeta()` - use the item's specific API methods to compare information such as colour, potion type etc.
-  - `Item->hasAnyDamageValue()` - for meta wildcard recipe ingredients, use `pocketmine\crafting\MetaWildcardRecipeIngredient` instead
-  - `ItemFactory->get()`
-    - To get an item at runtime, e.g. iron ingot, use `VanillaItems::IRON_INGOT()`
-    - To get a block as an item, e.g. stone, use `VanillaBlocks::STONE()->asItem()`
-    - To load an item from legacy ID and meta:
-      1. Use `GlobalItemDataHandlers::getUpgrader()->upgradeItemTypeDataInt()` to convert the legacy ID and meta to `ItemStackData`
-      2. Pass the itemstack data to `GlobalItemDataHandlers::getDeserializer()` to get an `Item` instance
-  - `ItemFactory->remap()`
-  - `ItemIdentifier->getId()`
-  - `ItemIdentifier->getMeta()`
-- The following API methods have been renamed:
-  - `Item::jsonDeserialize()` -> `Item::legacyJsonDeserialize()`
-  - `ItemFactory->getAllRegistered()` -> `ItemFactory->getAllKnownTypes()`
-- The following API methods have signature changes:
-  - `ItemFactory->isRegistered()` no longer accepts a `$variant` parameter, and now expects an item type ID for the ID parameter
-  - `ItemIdentifier->__construct()` no longer accepts a `$variant` parameter, and now expects an item type ID for the ID parameter
-  - `LegacyStringToItemParser->addMapping()` now accepts a string for ID, instead of an integer
-
-### `pocketmine\world`
-- The following classes have been added:
-  - `pocketmine\world\format\io\GlobalBlockStateHandlers`
-  - `pocketmine\world\format\io\GlobalItemDataHandlers`
