+# 5.0.0-ALPHA4
+Released 24th September 2022.
+
+## Core
+- Now targeting Minecraft: Bedrock 1.19.30.
+- 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.
+- Crashdumps now include JIT mode information for use by the Crash Archive.
+
+## Internals
+- Improved handling of "UI" inventories in network `InventoryManager`. Their contents are now synced correctly.
+
+## 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.
+
+### `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
+### 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
