+# 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]() is now supported.
+- [`ext-pmmpthread` version 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.
