+- [5.26.0](https://github.com/pmmp/PocketMine-MP/blob/5.26.0/changelogs/5.26.md#5260) - Performance improvements and other internal improvements
+
+## General
+- Aded support for Minecraft: Bedrock Edition 1.21.70.
+- Removed support for earlier versions.

+## General
+- Added support for Minecraft: Bedrock Edition 1.21.80.
+- Removed support for earlier versions.
+
+## Fixes
+- `AvailableEnchantmentRegistry` now requires provided tags to always be `string`. Previously, this wasn't enforced, leading to random crashes in core code related to enchanting.
+- `Entity->setFireTicks()` and `Entity->setOnFire()` now truncate the fire time to the max value instead of throwing exceptions.
+
+## Internals
+- Improved PHPStan error reporting for unsafe foreaches. Foreach on an array with implicit keys now generates different errors than foreach on an array with string keys.
+
+# 5.28.1
+Released 17th May 2025.
+
+## Fixes
+- Fixed errors when PlayStation players attempt to join due to null `TitleID`.
+
+# 5.28.2
+Released 17th May 2025.
+
+## Fixes
+- Fixed version constraints which were incorrectly updated during the 1.21.80 update. This led to an unnoticed failure to update BedrockProtocol in the previous patch release.

+
+## General
+- Added support for Minecraft: Bedrock Edition 1.21.90.
+- Removed support for earlier versions.
+
+## Fixes
+- Fixed thread crashes sometimes not reporting proper cause information in crashdumps.
+- Fixed crash when a plugin replaced a player's held tool with a different tool with a damage exceeding the old tool's max damage during an action.
+- Fixed performance issue of `PlayerAuthInputPacket` input flags handling (broken change detection).
+- Fixed `BaseInventory->addItem()` triggering updates on empty slots when no items were added.
+- Fixed slow check in `SubChunk` block layer garbage collection.
+
+## Internals
+- `LoginPacketHandler->processLogin()` signature has changed. This will break any plugins overriding `LoginPacketHandler`. As noted above, this is _not_ covered by the API version guarantee.
+- Automated branch sync for `minor-next` and `major-next` is now triggered by `repository_dispatch` from a cron job in this repository instead of `RestrictedActions`. The `RestrictedActions` cron job was getting automatically disabled by GitHub due to repo inactivity.

+# 5.30.0
+Released 18th June 2025.
+
+This is a minor feature release containing API additions, internals cleanup and user experience improvements.
+
+**Plugin compatibility:** Plugins for previous 5.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe` or `pocketmine\data` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.

+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## General
+- Significantly reduced log spam when unknown blocks, tiles and entities are found in saved worlds.
+- The file name structure for crashdumps has been changed to improve sorting order in file browsers.
+- Buffering is now skipped on the RakLib layer. In theory this could reduce player network latency by 10 ms (YMMV).
+
+## Gameplay
+### Blocks
+- Many blocks have had their hardness and blast resistance updated to match vanilla.
+- Implemented Respawn Anchor.
+- Melon Stem and Pumpkin Stem drop amounts should now match vanilla (using binomial distribution).
+
+## API
+## General
+- Verification of save registration has been added for blocks, entities and tiles. This is intended to make it easier to find mistakes when registering custom things, which previously would produce obscure core crashes.
+
+### `pocketmine\event\block`
+- The following classes have been added:
+  - `BlockPreExplodeEvent` - called before a block tries to explode
+  - `BlockExplodeEvent` - called when after a block's explosion calculation has been done, but before any changes are applied
+
+### `pocketmine\event\entity`
+- The following classes have been added:
+  - `EntityExtinguishEvent` - called when a burning entity is extinguished by water or other sources
+  - `EntityFrostWalkerEvent` - called every tick upon which an entity wearing Frost Walker boots moves; this can be used to customise or cancel the behaviour of the Frost Walker enchantment
+
+### `pocketmine\event\player`
+- The following classes have been added:
+  - `PlayerRespawnAnchorUseEvent` - called when a player interacts with a charged respawn anchor
+
+### `pocketmine\entity`
+- The following methods have been added:
+  - `public Entity->getStepHeight() : float`
+  - `public Entity->setStepHeight(float $stepHeight) : void`
+
+### `pocketmine\world\generator`
+- Generator execution has been decoupled from `PopulationTask` and async tasks in general. The following classes have been added:
+  - `executor\GeneratorExecutor`
+  - `executor\SyncGeneratorExecutor` - runs a generator on the main thread (used for flat world generation, which doesn't need threads)
+  - `executor\AsyncGeneratorExecutor` - runs a generator inside an async task, as before
+  - `PopulationUtils` - contains population business logic previously baked into `PopulationTask` - this permits the reuse of that logic outside async tasks
+- The following methods have signature changes:
+  - `GeneratorManager->addGenerator()` now accepts an optional `bool $fast` parameter, defaulting to `false`; setting this to `true` will cause your generator to run on the main thread
+- The following methods have been added:
+  - `public GeneratorManagerEntry->isFast() : bool` - returns whether this generator should run on the main thread
+- `PopulationTask` has been marked as `@internal`. In the next major version, it will move to the `generator\executor` namespace; however, for now it stays put because plugins currently have no other way to regenerate chunks.
+
+## Internals
+- World data version numbers have been consolidated in `pocketmine\data\bedrock\WorldDataVersions`. This removes the need to modify several different files to support new world versions, and reduces the chances of things getting missed.
+- Block hardness and blast resistance is now unit-tested against `block_properties_table.json` in `BedrockData`. This file comes from vanilla BDS, so we can use it to verify compliance.
+- Protocol-layer "server auth block breaking" has been enabled. Functionally, this is no different from the previous system, it just works differently on the network layer.
+- Various internal classes in the `pocketmine\world\generator` namespace have been moved to the `generator\executor` namespace.
+- Removed `World->registerGenerator()` and `World->unregisterGenerator()`.
+- Removed redundant calls to `curl_close()` (obsolete since PHP 8.0).
+
+# 5.30.1
+Released 23rd June 2025.
+
+## Fixes
+- Fixed accidental break of backwards compatibility in `EntityExplodeEvent` introduced in the previous release.
+- Fixed placement of player holding block when exploding respawn anchor.
+- Updated BedrockProtocol to fix incorrect encoding of `ServerScriptDebugDrawerPacket`.
+- Disabled client-side locator bar, allowing plugins to write their own implementations.

+
+## Performance
+- Worlds now remember when a chunk isn't generated. This reduces world I/O during world generation.
+- `BlockObjectToStateSerializer` now creates fewer objects in certain cases.
+
+## Gameplay
+- The following blocks have been added and/or are now properly supported:
+  - Hanging signs
+  - Illager banners
+
+## Tools
+- `generate-bedrock-data-from-packets.php` now represents items as strings directly when only an ID is present. This significantly improves readability in `BedrockData` and reduces file sizes.
+
+## API
+### `pocketmine\block`
+- Added (and implemented) interfaces for many common block properties, to allow `instanceof` to be used:
+  - `Ageable`: for blocks with age, such as crops
+  - `AnyFacing`: for blocks which can face up, down, and horizontal directions (not the same as `HorizontalFacing`!)
+  - `Colored`: for blocks with 16 `DyeColor` variants
+  - `CoralMaterial`: for coral blocks, provides access to coral type and dead/alive
+  - `HorizontalFacing`: for blocks which can **only** face horizontal directions (not the same as `AnyFacing`!)
+  - `Lightable`: for light-source blocks which can be turned on and off, e.g. redstone lamp
+  - `MultiAnyFacing`: for blocks which can appear in multiple faces of the same block (including up, down, and horizontal faces), e.g. glow lichen
+  - `PillarRotation`: for blocks which can be oriented on an axis, e.g. logs
+  - `PoweredByRedstone`: for blocks which receive power from a redstone component, e.g. redstone lamp
+  - `SignLikeRotation`: for blocks which can be rotated 16 ways, e.g. signs, banners
+  - `WoodMaterial`: for blocks made from wood
+  - These interfaces have been implemented on many blocks. For the sake of brevity, they are not listed here, but you can expect to see them wherever the corresponding traits were used.
+- The following classes have been added:
+  - `BaseOminousBanner`
+  - `CeilingCenterHangingSign` - both chains connected to the same point on the block above, can face 16 directions
+  - `CeilingEdgesHangingSign` - each chain connected to separate edges of the block above, can face 4 directions
+  - `OminousFloorBanner` - floor version of illager banner, can face 16 directions
+  - `OminousWallBanner` - wall version of illager banner, can face 4 directions
+  - `WallHangingSign` - hangs from a horizontal beam, can face 4 directions
+- The following API methods have been added:
+  - `public ChiseledBookshelf->setSlots(list<ChiseledBookshelfSlot> $slots) : $this`
+  - `public static VanillaBlocks` methods:
+    - `ACACIA_CEILING_CENTER_HANGING_SIGN() : CeilingCenterHangingSign`

+### `pocketmine\data\bedrock\block\convert`
+- A new system for symmetric block serializers and deserializers has been introduced.
+  - This allows registering both a serializer and a deserializer with the same code, meaning way less code
+  - It also eliminates information duplication and potential inconsistencies, improving maintainability.
+  - A proper way to deal with flattened IDs (e.g. color blocks) has been introduced which _doesn't_ require hardcoding a giant mess of IDs
+  - This symmetric system covers 99% of blocks which have a 1:1 association between PM and vanilla blocks, or 1:N where IDs are flattened
+  - However, there are still some special cases which require registering separate serializers and deserializers (usually in cases where the PM implementation deviates from Mojang where Mojang's implementation sucks, such as hanging signs or big dripleaf).
+  - No backwards compatibility breaks are expected as a result of this change. However, it's recommended to migrate old code to this new system for maintainability.
+  - The following new classes have been added:
+    - `BlockSerializerDeserializerRegistrar` - handles unified registration of block serializers and deserializers, based on a provided block model
+    - `FlattenedIdModel` - represents a block with some properties baked into its Minecraft ID, e.g. coral or color blocks
+    - `Model` - represents a regular block with all properties in its `states` NBT
+    - `property\BoolFromStringProperty<TBlock>` - property mapping a bool value from a string NBT state
+    - `property\BoolProperty<TBlock>`
+    - `property\CommonProperties` - singleton containing commonly-used block property definitions and groups, e.g. facing, stair properties
+    - `property\EnumFromRawStateMap<TEnum, TRaw>` - maps a raw NBT value to a PHP `enum` and vice versa
+    - `property\IntFromRawStateMap<TRaw>` - maps a raw NBT value to PM integer constants and vice versa
+    - `property\IntProperty<TBlock>` - an integer range property with a min, max, and optional offset
+    - `property\Property<TBlock>` - interface implemented by all property definitions accepted by a `Model` or `FlattenedIdModel`
+    - `property\StateMap<TValue, TRaw>` - interface implemented by classes accepted by mapping properties, e.g. `BoolFromStringProperty`
+    - `property\StringProperty<TBlock>` - interface implemented by properties whose raw outputs are strings - these can be used as ID components in `FlattenedIdModel`
+    - `property\ValueFromIntProperty<TBlock, TValue>` - property mapping a generic PM value from an int NBT state
+    - `property\ValueFromStringProperty<TBlock, TValue>` - same as above, but for a string NBT state
+    - `property\ValueSetFromIntProperty<TBlock, TOption>` - a property mapping an `int[]` or `enum[]` from a set of flags in NBT states
+    - `property\ValueMappings` - singleton containing commonly-needed `StateMap`s
+  - The following classes have been deprecated:
+    - `BlockStateDeserializerHelper`
+    - `BlockStateSerializerHelper`
+  - The following methods have been deprecated:
+    - All methods for decoding mapped property types in `BlockStateReader`, e.g. `readFacingDirection()`
+    - All methods for encoding mapped property types in `BlockStateWriter`, e.g. `writeFacingDirection()`
+    - All specific blocktype mapping functions in `BlockStateToObjectDeserializer`, e.g. `mapStairs()`
+    - All specific blocktype mapping functions in `BlockObjectToStateSerializer`, e.g. `mapStairs()`
+
+### `pocketmine\item`
+- The following hooks have been added:
+  - `public Item->getPlacementTransaction(Block $blockReplace, Block $blockClicked, int $face, Vector3 $clickVector, ?Player $player = null) : ?BlockTransaction` - allows more complex logic for itemblocks to place blocks, without duplicating their placement conditions (used for hanging signs)
+
+### `pocketmine\world`
+- `World->setChunk()` now verifies that blockstate IDs in the provided chunk are all registered in `RuntimeBlockStateRegistry`. This should provide earlier detection for custom block registration errors by plugins.
+
+## Internals
+- `BlockStateUpgrader` is now almost entirely independent from `BlockStateData`. It's anticipated that the upgrader library will be separable from the core in the future.
+- `Block->readStateFromWorld()` is now triggered on chunk load for any position containing a tile. This should allow more effective updating of blocks with properties in their tiles.
+
+# 5.33.1
+Released 31st August 2025.
+
+## Fixes
+- Fixed banners placed in prior versions getting their tiles deleted (due to missing `Type` tags).
