# 4.23.0
Released 12th July 2023.

**For Minecraft: Bedrock Edition 1.20.10**

This is a support release for Minecraft: Bedrock Edition 1.20.10.

**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.

## General
- Added support for Minecraft: Bedrock Edition 1.20.10.
- Removed support for older versions.

## Fixes
- Fixed Docker image build failure due to outdated `build/php` submodule.

# 4.23.1
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. 

# 4.23.5
Released 9th August 2023.

## General
- Updated translation data to [pmmp/Language 2.19.6](https://github.com/pmmp/Language/releases/tag/2.19.6).

## Fixes
- Fixed `PluginBase->saveResource()` leaking file resources when the data file already exists in the plugin's data folder. This bug existed since 2014 and was only discovered recently.
- Fixed coral blocks becoming dead after calling `getDropsForCompatibleTool()` on them.
- Fixed `BlockDeathEvent->getOldState()` returning a block which is already dead.

# 4.23.6
Released 21st August 2023.

## Fixes
- Added a workaround for armor and other inventories not working correctly after inventory sync. This is caused by a client bug.
