+- 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.

+**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
+Released 25th 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.
+- User-defined `pocketmine.yml` custom commands now use a generic description which makes clear the command is config-defined.
+- 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`
+  - The file must contain the raw key bytes, and must not end with a newline.
+
+## 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
+- 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 missing sounds when adding, rotating, or removing items in item frames.
+- Fixed modifier values for Instant Damage and Regeneration effects.
+- Implemented Darkness effect.
+- 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.
+    - This limit was causing a linear decrease in chunk ticking speed with larger numbers of players, leading to worsened gameplay experience.
+    - **Warning: This change will result in increased CPU usage if players are spread over a very large area.**
+  - Every chunk within the configured tick radius of a player will be ticked. Previously, chunks were randomly selected from the radius.
+
+## 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\event\block`
+- 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:
+  - `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\lang`
+- The following new API methods have been added:
+  - `public Language->getAll() : array<string, string>`
+
+### `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
+
+### `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
+
+### `pocketmine\world\sound`
+- The following new classes have been added:
+  - `ItemFrameAddItemSound`
+  - `ItemFrameRemoveItemSound`
+  - `ItemFrameRotateItemSound`
+
+## 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))
+- `DelegateInventory` now uses `WeakReference` to track its inventory listener. This allows the delegate to be reused. ([link](https://github.com/pmmp/PocketMine-MP/commit/3feaa18f6c10c3a99c0deca75f57ec2d74b92ab4))
+- 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.

+- 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.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

+**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.
+

+  - `BlockIdentifierFlattened`

+  - `CopperOre`
+  - `GoldOre`

+  - `Block->readStateFromData()`
+  - `Block->writeStateToMeta()`
+  - `Block->writeStateToItemMeta()`
+  - `Block->getStateBitmask()`
+  - `BlockFactory->get()`
+    - To get a block at runtime, e.g. stone, use `VanillaBlocks::STONE()`
+    - To load a block from old config or database data:
+      1. Use `GlobalBlockStateHandlers::getUpgrader()->upgradeIntIdMeta()` to convert it to modern data
+      2. Pass the data to `GlobalBlockStateHandlers::getDeserializer()` to get a blockstate ID
+      3. Pass the blockstate ID to `BlockFactory::fromStateId()` to get a `Block` instance
+  - `BlockIdentifier->getBlockId()`

+
+### `pocketmine\crafting`
+- The following classes have been added:
+  - `RecipeIngredient` interface
+  - `ExactRecipeIngredient` - matches an exact item
+  - `MetaWildcardRecipeIngredient` - matches an item with the given legacy Minecraft ID, but any metadata value
+- The following API methods have signature changes:
+  - `FurnaceRecipe->__construct()` now accepts `RecipeIngredient` instead of `Item`
+  - `FurnaceRecipe->getInput()` now returns `RecipeIngredient` instead of `Item`
+  - `PotionContainerChangeRecipe->__construct()` now accepts `string, RecipeIngredient, string` (using Minecraft string IDs instead of legacy integers).
+  - `PotionContainerChangeRecipe->getIngredient()` now returns `RecipeIngredient` instead of `Item`.
+  - `PotionContainerChangeRecipe->getInputItemId()` now returns `string` (using Minecraft string IDs instead of legacy integers).
+  - `PotionContainerChangeRecipe->getOutputItemId()` now returns `string` (using Minecraft string IDs instead of legacy integers).

+  - `ShapelessRecipe->__construct()` now accepts `RecipeIngredient` instead of `Item`
+  - `ShapelessRecipe->getIngredientList()` now returns `RecipeIngredient[]` instead of `Item[]`
+
+### `pocketmine\entity`
+- `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\block`
+- Dependency between `BlockFactory` and `VanillaBlocks` has been inverted.
+  - Now, blocks are defined in `VanillaBlocks`, and automatically registered in `BlockFactory`.
+  - Manual registration in `BlockFactory` is still required for custom blocks.
+  - `BlockFactory` now has only one purpose, which is to map internal blockstate IDs to `Block` objects when reading blocks from chunks.
+- The following new API methods have been added:
+  - `public Block->isFireProofAsItem()`
+  - `public Block->onProjectileHit()`
+  - `public ItemFrame->isGlowing()`
+  - `public ItemFrame->setGlowing()`
+- The following new classes have been added:

+
+### `pocketmine\crafting`
+- JSON models have been updated to reflect updated crafting data format.
+- The following enum classes have new members:
+  - `ShapelessRecipeType` has new members `CARTOGRAPHY` and `SMITHING`
+
+### `pocketmine\data`
+- `LegacyToStringBidirectionalIdMap` has been reduced to `LegacyToStringIdMap`.
+  - Since we never map from string ID to legacy ID, bidirectional mapping is no longer necessary.
+  - This affects the following subclasses:
+    - `LegacyBiomeIdToStringIdMap`
+    - `LegacyBlockIdToStringIdMap`
+    - `LegacyEntityIdToStringIdMap`
+    - `LegacyItemIdToStringIdMap`
+- The following internal API methods have been added:
+  - `public LegacyToStringIdMap->add(string $string, int $legacy) : void` - adds a mapping from a custom legacy ID to custom string ID, needed for upgrading old saved data
+  - `public LegacyBlockStateMapper->addMapping(string $stringId, int $intId, int $meta, BlockStateData $stateData) : void` - adds a mapping from legacy block data to a modern blockstate, needed for upgrading old saved data
+  - `public BlockStateData->getState(string $name) : ?Tag`
+- The following internal API methods have signature changes:
+  - `BlockStateData->__construct()` now accepts `array<string, Tag`> for `$states` instead of `CompoundTag`
+  - `BlockStateData->getStates()` now returns `array<string, Tag>` instead of `CompoundTag` (allows reducing memory usage)
+- The following classes have been added:
+  - `UnsupportedItemTypeException`
+
+### `pocketmine\item`
+- `ItemFactory` has been removed.
+  - Vanilla item registration is now done via `VanillaItems`.

+- The following API methods have been added:
+  - `public ArmorTypeInfo->getToughness() : int`
+  - `public ArmorTypeInfo->isFireProof() : bool`
+  - `public Item->isFireProof() : bool`
+- The following API methods have signature changes:
+  - `ArmorTypeInfo->__construct()` now accepts optional parameters `int $toughness` and `bool $fireProof`
+- The following classes have been added:
+  - `HoneyBottle`
+- The following enums have new members:
+  - `ToolTier` has new member `NETHERITE`
+
+### `pocketmine\world`
+- The following API methods have signature changes:
+  - `SubChunk->__construct()` parameter `$blocks` has been renamed to `$blockLayers`.
+- The following classes have been added:
+  - `CopperWaxApplySound`

+
+# 5.0.0-ALPHA3
+Released 14th August 2022.
+
+## Core
+- Support for Bedrock 1.19.20.
+- Dropped support for Bedrock versions older than 1.19.20.
+- Improved performance of dropping block inventory contents when the block is destroyed.
+
+## Fixes
+- Fixed errors when loading air itemstacks from PM4 worlds. These weren't supposed to exist (vanilla doesn't save them), but they were present in older PM worlds due to a bug in older versions.
+- Fixed server crash when discovering unknown blocks in non-leveldb worlds during conversion.
+- Fixed crimson / warped planks being usable as furnace fuel.
+
+## Gameplay
+### Blocks
+- Added the following new blocks:
+  - Cauldron
+  - Chorus Flower
+  - Chorus Plant
+  - Froglight (pearlescent, verdant, ochre)
+  - Mangrove Roots
+  - Muddy Mangrove Roots
+  - Rooted Dirt
+  - Spore Blossom
+- Fixed lava setting entities on fire for an incorrect duration (Java vs Bedrock inconsistency).
+
+### Items
+- Glass bottles can now be filled with water by clicking on a water source block.
+
+## API
+### `pocketmine\block`
+#### Highlights
+- Introduced "type tags" concept, which allows marking certain blocks as having certain behaviours.
+  - The idea for this system was borrowed from the Minecraft Java tags system.
+  - It's still in very early concept stage, but is currently used for deciding which types of blocks plants can be placed on without needing to enumerate every single ID in every class, eliminating a bunch of boilerplate code and improving consistency.
+- All `Block` descendents now accept `BlockTypeInfo` in the constructor, instead of `BlockBreakInfo`.
+  - This allows for future additions without needing to change dozens of overridden constructors.
+- Dynamic type and state property serialization now each use a single, unified method (`describeType` and `describeState` respectively) which accept `RuntimeDataReader|RuntimeDataWriter`, instead of separate decode/encode methods.
+  - This simplifies implementing new blocks and avoids duplication of information.
+- `&$returnedItems` reference parameter is now used in some places to enable actions to return items to players without caring about whether they are in creative or anything else.
+  - This eliminates boilerplate code of deciding whether to set the player's held item or not, as well as automatically dropping any overflow items that don't fit into the inventory.
+  - This is currently used when filling/emptying cauldrons using buckets or glass bottles.
+- `BlockTypeIds` now exposes `newId()` static method to ease addition of custom blocks.
+
+#### Changes
+- The following API methods have signature changes:
+  - `Block->onInteract()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Block->onBreak()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Block->readStateFromWorld()` now returns `Block`.
+    - This allows blocks to replace themselves with a different block entirely based on world conditions.
+- The following new classes have been added:
+  - `BlockTypeInfo`
+  - `BlockTypeTags`
+- The following new API methods have been added:
+  - `protected Block->describeState(RuntimeDataReader|RuntimeDataWriter $w) : void` - describes to a runtime data reader/writer how to read/write the block's state properties
+  - `protected Block->describeType(RuntimeDataReader|RuntimeDataWriter $w) : void` - describes to a runtime data reader/writer how to read/write the block's dynamic type properties
+  - `public Block->getTypeTags() : array<string>`
+  - `public Block->hasTypeTag(string $tag) : bool`
+  - `public Spawnable->getRenderUpdateBugWorkaroundStateProperties(Block $block) : array<string, Tag>` - allows spawnable tiles to spoof block state properties to work around client-side rendering bugs without actually changing the block server-side
+  - `public static BlockBreakInfo::axe(float $hardness, ?ToolTier $toolTier = null, ?float $blastResistance = null) : BlockBreakInfo`
+  - `public static BlockBreakInfo::pickaxe(float $hardness, ?ToolTier $toolTier = null, ?float $blastResistance = null) : BlockBreakInfo`
+  - `public static BlockBreakInfo::shovel(float $hardness, ?ToolTier $toolTier = null, ?float $blastResistance = null) : BlockBreakInfo`
+  - `public static BlockBreakInfo::tier(float $hardness, int $toolType, ToolTier $toolTier, ?float $blastResistance = null) : BlockBreakInfo`
+  - `public static BlockTypeIds::newId() : int` - returns a new dynamic block type ID for use by custom blocks
+
+### `pocketmine\data`
+- The following classes have been renamed:
+  - `LegacyBlockStateMapper` -> `BlockIdMetaUpgrader`
+- The following API methods have been added:
+  - `public BlockDataUpgrader->getIdMetaUpgrader() : BlockIdMetaUpgrader`
+  - `public BlockIdMetaUpgrader->addIdMetaToStateMapping(string $stringId, int $meta, BlockStateData $stateData) : void`
+  - `public BlockIdMetaUpgrader->addIntIdToStringIdMapping(int $intId, string $stringId) : void`
+- The following API methods have been removed:
+  - `BlockIdMetaUpgrader->addMapping()` - use `addIdMetaToStateMapping()` (and `addIntIdToStringIdMapping()` if necessary) instead
+- `LegacyToStringMap` no longer throws exceptions when adding the same mapping twice if the addition would have no effect.
+
+### `pocketmine\item`
+#### Highlights
+- `&$returnedItems` reference parameter is now used in some places to enable actions to return items to players without caring about whether they are in creative or anything else.
+  - This eliminates boilerplate code of deciding whether to set the player's held item or not, as well as automatically dropping any overflow items that don't fit into the inventory.
+  - This is used for things like filling/emptying buckets and bottles, and equipping armor.
+
+#### Changes
+- The following new API methods have been added:
+  - `public Armor->clearCustomColor() : $this` - clears the custom color of an armor item
+  - `public static ItemTypeIds::newId() : int` - returns a new dynamic item type ID for use by custom items
+- The following API methods have signature changes:
+  - `Item->onAttackEntity()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onClickAir()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onDestroyBlock()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onInteractBlock()` now accepts `array<Item> &$returnedItems` reference parameter.
+  - `Item->onReleaseUsing()` now accepts `array<Item> &$returnedItems` reference parameter.
+
+# 5.0.0-ALPHA4
+Released 24th September 2022.
+
+## Core
+- Now targeting Minecraft: Bedrock 1.19.30.
+- All tests and static analysis are now being run on PHP 8.1 as well as PHP 8.0.
+- Silenced warning about Xdebug when it's loaded but disabled by `xdebug.mode` configuration.
+- A new `console.enable-input` option has been added to `pocketmine.yml`, which allows disabling the console reader in environments where it's not needed (e.g. a Docker container). This can be useful to save processor and memory resources.
+- Console reader polling is now done on the main thread. Since the console reader communication is now done via sockets, there's no longer any reason for it to have its own thread.
+- Crashdumps now include JIT mode information for use by the Crash Archive.
+- Improved handling of "UI" inventories in network `InventoryManager`. Their contents are now synced correctly.
+- Fixed cartography table recipes pretending to be smithing table recipes in `CraftingDataPacket`.
+- Fixed incorrect key being used for saving entity type IDs in save data.
+
+## API
+### General
+- Plugin dependents are now always disabled before their dependencies on shutdown, to ensure that the dependents can finish what they are doing correctly.
+
+### `pocketmine\block`
+- The following new API methods have been added:
+  - `public SignText->isGlowing() : bool`
+  - `public SignText->getBaseColor() : pocketmine\color\Color`
+- The following API methods have signature changes:
+  - `SignText::fromBlob()` now accepts two new optional parameters: `?Color $baseColor` and `bool $glowing`
+  - `SignText::__construct()` now accepts two new optional parameters: `?Color $baseColor` and `bool $glowing`
+- The following API methods have been removed:
+  - `TreeType::fromMagicNumber()`
+  - `TreeType->getMagicNumber()`
+
+### `pocketmine\command`
+- Command permissions are now always checked by the server when running a command.
+  - This only affects commands implemented by extending `Command`. Plugins using `PluginBase->onCommand()` are not affected by this change, since they already had permissions checked by the server anyway.
+  - Previously, direct inheritors of `Command` were responsible for checking permissions, which required developers to duplicate the same code in every command, and opened lots of potential for security vulnerabilities.
+  - If you want to do something on permission denied (e.g. sending a special message, or audit logging), you can do so by overriding `Command->testPermission()`, instead of baking the code directly into `Command->execute()`.
+  - If you don't want to use permissions at all, just create a permission with a default of `true` (or belonging to `pocketmine.group.user`) and assign that.
+
+### `pocketmine\data`
+#### Highlights
+- Introduced an experimental, mostly unified item (de)serializer registrar, `ItemSerializerDeserializerRegistrar`.
+  - This class includes helper methods to register symmetric serializer and deserializer callbacks into an `ItemSerializer` and `ItemDeserializer`.
+  - This halves the amount of code needed to register new items in the vast majority of cases.
+  - This is currently used to register all currently implemented items.
+
+#### Other changes
+- The following classes have been renamed:
+  - `BlockObjectToBlockStateSerializer` -> `BlockObjectToStateSerializer`
+  - `BlockStateToBlockObjectDeserializer` -> `BlockStateToObjectDeserializer`
+- The following classes have been removed:
+  - `CachingBlockStateDeserializer`
+  - `CachingBlockStateSerializer`
+  - `DelegatingBlockStateDeserializer`
+  - `DelegatingBlockStateSerializer`
+- The following new API methods have been added:
+  - `public BlockStateToObjectDeserializer->mapSimple(string $stringId, \Closure() : Block $getBlock) : void` - for symmetry with the serializer
+
+### `pocketmine\event`
+- `BlockFormEvent` now includes information about the block which caused the event.
+  - Added `public BlockFormEvent->getCausingBlock() : Block`
+
+### `pocketmine\inventory`
+- Introduced a new `TransactionBuilder` class, which considerably simplifies the process of constructing an `InventoryTransaction` from generic `setItem()` calls.
+  - This is currently used to build server-side transactions for evicting the contents of the crafting grid when closing the main inventory.
+  - This is planned for use with the new Minecraft Bedrock item stack request system.
+- Improved PHPStan type information available for `Inventory` and `BaseInventory`.
+
+### `pocketmine\item`
+- The following API methods have been changed:
+  - `Item->encodeType(RuntimeDataWriter $w) : void` -> `Item->describeType(RuntimeDataReader|RuntimeDataWriter $w) : void`
+- The following new classes have been added:
+  - `SuspiciousStew`
+  - `SuspiciousStewType`
+
+### `pocketmine\utils`
+- The following new API methods have been added:
+  - `public static Utils::getOpcacheJitMode() : int`
+
+### `pocketmine\world`
+- The following new classes have been added:
+  - `sound\DyeUseSound`
+  - `sound\InkSacUseSound`
+- The following API methods have changed signatures:
+  - `GlobalBlockStateHandlers::getSerializer()` now returns `BlockObjectToStateSerializer` directly instead of `BlockStateSerializer`.
+  - `GlobalBlockStateHandlers::getDeserializer()` now returns `BlockStateToObjectDeserializer` directly instead of `BlockStateDeserializer`.
+
+## Gameplay
+### General
+- Spectator players are no longer able to acquire blocks by block picking that they don't already have in their inventories. The behaviour is now the same as survival mode.
+
+### Blocks
+- Coral and coral fans now behave correctly when placed out of water (they no longer immediately die).
+- Added support for dyeing sign text and making it glow.
+- Fixed dead bush being able to be placed on some invalid blocks (e.g. stone).
+- TNT can now be ignited by fire charges.
+- Vines can now only be placed on the side of full-cube blocks.
+- Fixed sugarcane not being able to be placed on some blocks.
+
+### Items
+- Added the following new items:
+  - Fire Charge
+  - Suspicious Stew
+
+### Effects

+  - `World->setBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`
+
+#### `pocketmine\world\format`
+- The following new API methods have been added:
+  - `public SubChunk->getBiomeArray() : PalettedBlockArray`
+- The following API methods have changed signatures:
+  - `Chunk->getBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`
+  - `Chunk->setBiomeId()` now accepts `int $x, int $y, int $z` instead of `int $x, int $z`
+  - `Chunk->__construct()` no longer accepts `BiomeArray` as a parameter (contained in each subchunk instead)
+  - `SubChunk->__construct()` now accepts `int $emptyBlockId, list<PalettedBlockArray> $blocks, PalettedBlockArray $biomes, ?LightArray $blockLight, ?LightArray $skyLight` instead of `int, list<PalettedBlockArray>, ?LightArray, ?LightArray` 
+- The following classes have been removed
+  - `BiomeArray`
+
+## Internals
+- Built-in commands now declare their names inside the class constructor, rather than accepting them as parameters. This improves code consistency.
+- `NetworkSession` disconnect APIs now accept `Translatable|string` instead of `string` to allow localized disconnect messages.
+- All external usages of `KnownTranslationKeys` are now removed. All localized messages are now sent using `Translatable` objects (usually from `KnownTranslationFactory`).
+
+# 5.0.0-ALPHA8
+Released 23rd January 2023.
+
+## Core
+- Updated `ext-pthreads` requirement to `^5.1.0`. This version improves performance, memory usage, includes BC-breaking API changes, and removes a lot of confusing behaviour.
+  - See [`ext-pthreads` 5.0.0 release](https://github.com/pmmp/pthreads/releases/tag/5.0.0) for more information.
+  - For the most part, plugins will be unaffected, unless using `Threaded` objects directly, or directly interacting with other pthreads APIs.
+
+## API
+### Overview
+- It's now possible to specify a different disconnect reason and disconnection screen message. This is useful if you want to display a fancy disconnect screen, but don't want to spam the server log with useless information.
+
+### `pocketmine\event\player`
+- The following API methods have been removed:
+  - `PlayerKickEvent->getReason()` - replaced by `getDisconnectReason()` and `getDisconnectScreenMessage()`
+  - `PlayerKickEvent->setReason()` - replaced by `setDisconnectReason()` and `setDisconnectScreenMessage()`
+  - `PlayerDuplicateLoginEvent->getDisconnectMessage()` - replaced by `getDisconnectReason()` and `getDisconnectScreenMessage()`
+  - `PlayerDuplicateLoginEvent->setDisconnectMessage()` - replaced by `setDisconnectReason()` and `setDisconnectScreenMessage()`
+- The following new API methods have been added:
+  - `public PlayerKickEvent->getDisconnectReason() : Translatable|string` - returns the reason for the disconnection displayed in the console and server log
+  - `public PlayerKickEvent->setDisconnectReason(Translatable|string $disconnectReason) : void` - sets the reason for the disconnection displayed in the console and server log
+  - `public PlayerKickEvent->getDisconnectScreenMessage() : Translatable|string|null` - returns the message to be displayed on the disconnect screen (the message in `getDisconnectReason()` is used if null is returned)
+  - `public PlayerKickEvent->setDisconnectScreenMessage(Translatable|string|null $disconnectScreenMessage) : void` - sets the message to be displayed on the disconnect screen (the message in `setDisconnectReason()` is used if null is passed)
+  - `public PlayerDuplicateLoginEvent->getDisconnectReason() : Translatable|string` - returns the reason for the disconnection displayed in the console and server log
+  - `public PlayerDuplicateLoginEvent->setDisconnectReason(Translatable|string $disconnectReason) : void` - sets the reason for the disconnection displayed in the console and server log
+  - `public PlayerDuplicateLoginEvent->getDisconnectScreenMessage() : Translatable|string|null` - returns the message to be displayed on the disconnect screen (the message in `getDisconnectReason()` is used if null is returned)
+  - `public PlayerDuplicateLoginEvent->setDisconnectScreenMessage(Translatable|string|null $disconnectScreenMessage) : void` - sets the message to be displayed on the disconnect screen (the message in `setDisconnectReason()` is used if null is passed)
+
+### `pocketmine\network`
+- The following API methods have changed signatures:
+  - `NetworkSessionManager->close()` now accepts an additional `Translatable|string|null $disconnectScreenMessage` parameter.
+
+### `pocketmine\player`
+- The following API methods have changed signatures:
+  - `Player->kick()` now accepts an additional `Translatable|string|null $disconnectScreenMessage` parameter, which is the message to be displayed on the disconnect screen (the message in `$reason` is used if null is passed)
+  - `Player->disconnect()` now accepts an additional `Translatable|string|null $disconnectScreenMessage` parameter, which is the message to be displayed on the disconnect screen (the message in `$reason` is used if null is passed)
+
+## Internals
+- `NetworkSession` disconnect methods have been altered to allow specifying a different disconnect reason and disconnection screen message.
