Release 5.4.0

this needs to be dealt with before release otherwise we'll be stuck with FortuneDropHelper::grass()
this is the obvious solution and should have been done some time ago - stuff like flammability was already a problem for double tall grass anyway

+# 4.22.0
+Released 7th June 2023.
+
+**For Minecraft: Bedrock Edition 1.20.0**
+
+This is a support release for Minecraft: Bedrock Edition 1.20.0.
+
+**Plugin compatibility:** Plugins for previous 4.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## Interim releases
+If you're upgrading from 4.20.x directly to 4.22.x, please also read the following changelogs, as the interim releases contain important changes:
+- [4.21.0](https://github.com/pmmp/PocketMine-MP/blob/4.22.0/changelogs/4.21.md#4210) - PHP 8.1 minimum version, minor performance improvements
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.20.0.
+- Removed support for older versions.
+
+## Fixes
+- Removed deprecated `ReflectionProperty::setAccessible()` calls.
+- Fixed jukebox music not stopping when destroyed by an explosion.
+
+# 4.22.1
+Released 9th June 2023.
+
+## Fixes
+- Replaced workaround for an old teleporting client bug:
+  - This workaround broke due to an additional client bug introduced by 1.20, causing players to become frozen to observers when teleported.
+  - The original client bug has still not been fixed, meaning a new workaround was needed, but no perfect solution could be found.
+  - The new workaround involves broadcasting teleport movements as regular movements, which causes unwanted interpolation between the old and new positions, but otherwise works correctly. This solution is not ideal, but it is the best we can do for now.
+  - See issues [#4394](https://github.com/pmmp/PocketMine-MP/issues/4394) and [#5810](https://github.com/pmmp/PocketMine-MP/issues/5810) for more details.
+
+# 4.22.2
+Released 1st July 2023.
+
+## Changes
+- Added obsoletion warnings to the server log at the end of the startup sequence.
+
+## Fixes
+- Fixed players being disconnected en masse with "Not authenticated" messages.
+  - This occurred due to a check intended to disable the old authentication key after July 1st.
+  - We expected that the new key would have been deployed by Mojang by now, but it seems like that has not yet happened.
+  - Due to the lack of a hard date for the key changeover, we guessed that July 1st would be a safe bet, but this appears to have backfired.
+  - This version will accept both old and new keys indefinitely.
+  - A security release will be published to remove the old key after the transition occurs.
+
+# 4.22.3
+Released 11th July 2023.
+
+## Fixes
+- Fixed mishandling of NBT leading to a server crash when editing signs.
+- Fixed an edge case crash that could occur in `AsyncTask->__destruct()` when thread-local storage referenced other `AsyncTask` objects.
+
+## Internals
+- Added a concurrency lock to prevent the `update-updater-api` GitHub Action from running for multiple releases at the same time (which would have caused one of them to fail due to git conflicts).

+Released 14th July 2023.
+
+## Fixes
+- Hardened validation of JWT signing keys in `LoginPacket`.
+- Fixed server crash due to a bug in upstream dependency [`netresearch/jsonmapper`](https://github.com/cweiske/JsonMapper).
+
+# 4.23.2
+Released 18th July 2023.
+
+## Fixes
+- Fixed login errors due to a new `sandboxId` field appearing in the Xbox Live authentication data in `LoginPacket`. All clients, regardless of version, are affected by this change.
+
+# 4.23.3
+Released 24th July 2023.
+
+## Documentation
+- Fixed typo in `ChunkSelector::selectChunks()` documentation.
+
+## Fixes
+- Fixed the server not stopping properly during crash conditions on *nix platforms.
+- Fixed `HORSE_EQUIP` and `SMITHING_TABLE_TEMPLATE` container UI types not being handled by `ItemStackContainerIdTranslator`. This bug prevented plugins from implementing missing inventory types.
+- Player emotes no longer broadcast messages to other players. This was unintended behaviour caused by a client-side behavioural change.
+- Shulker boxes no longer support the placement of torches or other similar blocks.
+- Fire can now be placed on upper slabs and the top of upside-down stairs.
+
+# 4.23.4
+Released 1st August 2023.
+
+## Fixes
+- Fixed exponentially increasing lag when many hundreds of non-mergeable dropped items occupied the same space. This disproportionately affected SkyBlock servers due to large cactus farms using water to collect items together.

+## General
+- Updated logos to new RGB-style logo. Thanks to @MrCakeSlayer and @HBIDamian for their efforts.
+- Improved error messages generated by the world system when some version tags are missing from `level.dat` in Bedrock worlds.
+- Outsourced Composer dependencies now only receive patch updates automatically (pinned using the `~` constraint).
+  - Minor and major updates now require manually updating `composer.json`, to ensure that the plugin API is not broken by libraries getting randomly updated from one patch release to the next.
+
+## Documentation
+- Updated doc comment for `Player->setGamemode()` to remove outdated information.
+- Added documentation for the `$clickVector` parameter of `Block->onInteract()` to specify that it is relative to the block's position.

+
+## Fixes
+- Fixed blue candles not appearing in the creative inventory.
+- Fixed server crash when block-picking candle cakes.
+- `World->useItemOn()` now ensures that the `$clickVector` components are always in the range of 0-1. Previously, any invalid values were accepted, potentially leading to a crash.

+# 5.2.0
+Released 4th July 2023.
+
+**For Minecraft: Bedrock Edition 1.20.0**
+
+This is a minor technical update, including changes to AsyncTask error handling and support for BedrockBlockUpgradeSchema version 3.0.0.
+
+**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.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## Core
+- [BedrockBlockUpgradeSchema version 3.0.0](https://github.com/pmmp/BedrockBlockUpgradeSchema/releases/tag/3.0.0) is now supported.
+- [`ext-pmmpthread` version 6.0.4](https://github.com/pmmp/ext-pmmpthread/releases/tag/6.0.4) is now required (bug fixes required to support technical changes in this release).
+
+## Performance
+- Improved performance of `AsyncPool->submitTask()` and `AsyncPool->submitTaskToWorker()`.
+- Added new timings for `AsyncTask->onProgressUpdate()` and `AsyncTask->onCompletion()`.
+
+## Gameplay
+### Blocks
+- Added the following new blocks:
+  - Cherry Button
+  - Cherry Door
+  - Cherry Fence
+  - Cherry Fence Gate
+  - Cherry Leaves
+  - Cherry Log
+  - Cherry Planks
+  - Cherry Pressure Plate
+  - Cherry Sign
+  - Cherry Slab
+  - Cherry Stairs
+  - Cherry Trapdoor
+  - Cherry Wood
+  - Glow Lichen
+  - Piglin Head
+
+## Tools
+- `generate-block-upgrade-schema.php` now supports generating schemas a la BedrockBlockUpgradeSchema version 3.0.0, using `newFlattenedName` to reduce schema size.
+- Improved property remapping detection in `generate-block-upgrade-schema.php`. It now detects related properties with more confidence (even when multiple properties were change), and no longer considers unrelated properties as mapped (e.g. `mapped_type` and `deprecated` in 1.9->1.10).
+
+## API
+### `pocketmine\data\bedrock\block`
+- The following new API methods have been added:
+  - `public BlockStateData->toVanillaNbt() : CompoundTag` - returns the NBT for the blockstate without any PMMP extra metadata (`toNbt()` will normally include a `PMMPDataVersion` tag).
+
+### `pocketmine\data\runtime`
+- The following new API methods have been added:
+  - `public RuntimeDataDescriber->facingFlags(list<int> $faces) : void`
+
+### `pocketmine\scheduler`
+- `AsyncTask->onRun()` no longer tolerates uncaught exceptions.
+  - This means that any uncaught exceptions thrown from `AsyncTask->onRun()` will now crash the worker thread, and by extension, the server.
+  - This change makes it easier to debug errors by detecting them earlier.
+- The following API methods have been deprecated:
+  - `AsyncTask->onError()`
+
+## Internals
+- `AsyncTask->progressUpdates` is now lazily initialized when a task publishes a progress update.
+  - This was previously not possible due to technical limitations of the `ext-pmmpthread` extension.
+  - This change improves performance of `AsyncPool->submitTask()` and `AsyncPool->submitTaskToWorker()`, as well as reducing the amount of work needed to check for progress updates on tick.
+- Errors in `AsyncWorker` now cascade and crash the whole server.
+  - This makes it easier to debug errors by detecting them earlier.
+  - This includes all types of unexpected errors, such as OOM, uncaught exceptions, etc.
+  - This change is not expected to affect normal server operation, as worker threads are not expected to crash under normal circumstances.
+- `AsyncTask::$threadLocalStorage` now uses a plain `array` instead of `ArrayObject`. The `ArrayObject` was a workaround for `ext-pthreads` to prevent thread-locals getting copied to the worker thread, and is no longer necessary.
+- Regenerated `pocketmine\data\bedrock\item\ItemTypeNames` for Bedrock 1.20 (BC breaking, some item names have changed).
+- Fixed `build/generate-item-type-names.php` not including some newer blockitems, such as doors and hanging signs.
+
+# 5.2.1
+Released 11th July 2023.
+
+**This release includes changes from the following releases:**
+- [4.22.3](https://github.com/pmmp/PocketMine-MP/blob/4.22.3/changelogs/4.22.md#4223) - Fixes for some crash issues
+
+This release contains no other changes.

+
+## Internals
+- Armor pieces are no longer set back into the armor inventory if no change was made. This reduces the number of slot updates sent to clients, as well as avoiding unnecessary updates for armor pieces which have Unbreaking enchantments.

+- [4.23.3](https://github.com/pmmp/PocketMine-MP/blob/4.23.3/changelogs/4.23.md#4233) - Various bug fixes
+
+## Fixes
+- Added a workaround for PM4 worlds with chunks corrupted by [Refaltor77/CustomItemAPI](https://github.com/Refaltor77/CustomItemAPI).
+  - While this was not the fault of PocketMine-MP itself, a significant number of users were affected by this problem.
+  - This error was not detected by PM4 due to missing validation of certain data which should not have existed in 1.12.
+  - An error will now be logged when this corruption is detected, but the affected chunks should otherwise load normally.
+- Relaxed validation of expected 3D biome array counts per chunk in LevelDB worlds.
+  - Vanilla Bedrock currently saves 24 palettes (and only 24 are required), but it saved 25, 32, or 64 biome palettes per chunk in older versions.
+  - Core validation for these padding biomes was very strict, enforcing exact compliance with vanilla.
+  - Since only 24 palettes are actually required, the remaining palettes may now be omitted irrespective of the chunk version.
+  - An error will still be logged when this mistake is detected, but the affected chunks will otherwise load normally.
+- Fixed `/kill` not working on players who had (re)spawned in the 3 seconds immediately after (re)spawning (due to `noDamageTicks`).
+- Fixed `/kill` not working correctly for players with high levels of Health Boost or other health-altering effects.
+- Fixed netherite items being destroyed by lava.
+- Fireproof entities no longer display the burning animation when in fire or lava. This does not apply to creative players, who are immortal rather than being fireproof.
+- Fixed frosted ice melting in certain conditions which didn't match vanilla Bedrock.
+
+# 5.3.4
+Released 1st August 2023.
+
+## Included releases
+This release includes changes from the following releases:
+- [4.23.4](https://github.com/pmmp/PocketMine-MP/blob/4.23.4/changelogs/4.23.md#4234) - Item entity lag fix

+# 5.4.0
+Released 1st August 2023.
+
+**For Minecraft: Bedrock Edition 1.20.10**
+
+This is a minor feature update, including a handful of new gameplay features, new plugin APIs and improvements to error reporting.
+
+**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.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## General
+- Improved error reporting for async task and thread crashes.
+- Players may now have different creative inventories.
+
+## Gameplay
+### General
+- Added support for 1.5-block height sneaking.
+- Fixed missing player arm swing and sounds when punching the air.
+
+### Blocks
+- Implemented the following new blocks:
+  - Big Dripleaf Head
+  - Big Dripleaf Stem
+  - Small Dripleaf
+- Acacia saplings now grow into acacia trees.
+- Fixed melon and pumpkin stems not attaching to the correct block when growing.
+- Various blocks now drop more items when mined with a compatible tool enchanted with Fortune.
+
+### Items
+- Implemented Strong Slowness potion.
+- Implemented Fortune enchantment.
+
+## API
+### `pocketmine\block`
+- The following new classes have been added:
+  - `utils\FortuneDropHelper` - utility methods for calculating the drop counts for Fortune-affected blocks
+- The following new API methods have been added:
+  - `protected Block->getAdjacentSupportType(int $facing) : utils\SupportType` - returns the type of support provided by the block in the given direction on the adjacent face
+
+### `pocketmine\entity`
+- The following new API constants have been added:
+  - `Living::DEFAULT_KNOCKBACK_FORCE`
+  - `Living::DEFAULT_KNOCKBACK_VERTICAL_LIMIT`
+
+### `pocketmine\entity\animation`
+- `ConsumingItemAnimation` now accepts `Living` instances instead of just `Human`.
+
+### `pocketmine\event`
+- The following new classes have been added:
+  - `PlayerMissSwingEvent` - called when the player attempts the attack action (left click on desktop) without any target
+    - This is possible thanks to the introduction of new flags in `PlayerAuthInputPacket` in Bedrock 1.20.10
+- The following new API methods have been added:
+  - `public EntityDamageByEntityEvent->getVerticalKnockBackLimit() : float`
+  - `public EntityDamageByEntityEvent->setVerticalKnockBackLimit(float $verticalKnockBackLimit) : void` - sets the max vertical velocity that can result from the victim being knocked back
+
+### `pocketmine\player`
+- The following new API methods have been added:
+  - `public Player->getCreativeInventory() : pocketmine\inventory\CreativeInventory`
+  - `public Player->setCreativeInventory(pocketmine\inventory\CreativeInventory $inventory) : void`
+  - `public Player->missSwing() : void` - performs actions associated with the attack action when there is no target (see `PlayerMissSwingEvent`)
+
+### `pocketmine\scheduler`
+- Cancellation functionality has been removed from `AsyncTask`, as it didn't make any sense and wasn't used by anything for what it was intended for.
+  - It broke sequential task execution - later tasks might depend on state from earlier tasks
+  - It didn't actually cancel the task anyway - at best, it prevented it from running, but couldn't interrupt it (though interrupting a task does not make sense either)
+- The following API methods have been deprecated, and their functionality has been removed:
+  - `AsyncTask->hasCancelledRun()`
+  - `AsyncTask->cancelRun()`
+
+## Internals
+- Uncaught exceptions and fatal errors in `AsyncTask`, threads extending `pocketmine\thread\Thread`, and `pocketmine\thread\Worker` are now recorded in crashdumps, making it significantly easier to debug errors in these areas.
+- JWT signature DER <-> raw conversions are now handled in-house using code in `JwtUtils`
+  - Due to the simplicity of the conversion and only requiring a tiny subset of the ASN.1 spec, it didn't make much sense to introduce another dependency.
+  - `fgrosse/phpasn1` is no longer required. This package was abandoned by its author and only used by PocketMine-MP for this one purpose.
+- Various usages of `Closure::fromCallable()` have been replaced by PHP 8.1 first-class callable syntax.
+- Blocks requiring support shifted to a "can be supported at" model, rather than "can be supported by".
+  - This model reduces repeated logic when placing and performing nearby block updates (no need to hardcode facing everywhere).
+  - In addition, this change facilitates the use of the newly introduced `Block->getAdjacentSupportType()` API method, reducing boilerplate support-type checking code.
+- Bell block code has been simplified and cleaned up.
+- `TallGrass` and `DoubleTallGrass` now use a shared `TallGrassTrait` to reduce code duplication.
