+## Choosing a target branch
+PocketMine-MP has three primary branches of development.

+|:---------------|:--------:|:------------:|:------------:|
+| Bug fixes | ✔️ | ✔️ | ✔️ |
+| Improvements to API docs | ✔️ | ✔️ | ✔️ |
+| Cleaning up code | ❌ | ✔️ | ✔️ |
+| Changing code formatting or style | ❌ | ✔️ | ✔️ |

+
+### Notes
+- **Non-disruptive** means that usage should not be significantly altered by the change.
+  - Examples of **non-disruptive** changes include adding new commands, or gameplay features like blocks and items.
+  - Examples of **disruptive** changes include changing the way the server is run, world format changes (since those require downtime for the user to convert their world).
+- **API** includes all public and protected classes, functions and constants (unless marked as `@internal`).
+  - Private members are not part of the API, **unless in a trait**.

 ## Making a pull request
 The basic procedure to create a pull request is:
 1. [Fork the repository on GitHub](https://github.com/pmmp/PocketMine-MP/fork). This gives you your own copy of the repository to make changes to.

@ -29,3 +29,18 @@ Released 16th August 2022.
 - Fixed crash when processing player skins with invalid geometry data.
 - Fixed spectator players being able to pick blocks using mousewheel click.
 - Improved supporting requirements for sugarcane.

+# 4.7.3
+Released 22nd August 2022.
+
+## General
+- Added complete translations for Spanish and Vietnamese.
+- All continuous integration (static analysis, unit tests, integration tests) are now performed on PHP 8.1 as well as 8.0.
+- InventoryTransaction now verifies that stack sizes of items after the transaction don't exceed the maximum stack size of the item type or the containing inventory.
+
+## Fixes
+- Fixed Normal generator crash on PHP 8.1.
+- Fixed a race condition during async worker shutdown that could lead to tasks executing in the wrong order. This (very rarely) led to a crash in `PopulationTask` due to its preceding `GeneratorRegisterTask` not being executed.
+- Fixed `/give` accepting negative amounts or amounts larger than 32767 (vanilla max).
+- Fixed placement conditions for vines (no longer able to be placed on the side of cacti).
+- Fixed incorrect documentation of `SignText::__construct()`.

+

+
+# 4.9.0
+Released 20th September 2022.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.19.30.
+- Removed support for older versions.
+
+# 4.9.1
+Released 11th October 2022.
+
+## Documentation
+- Added and improved documentation for many API methods in `Player` and `Block`.
+- Added missing `@internal` tag for `TaskHandler->setNextRun()`, `TaskHandler->remove()` and `TaskHandler->run()`.
+
+## Fixes
+- Flight state is now locked by the server in spectator mode. This prevents any attempt by the client to toggle flight mode.
+- Fixed entity health exceeding its max health after the expiry of Health Boost effect.
+- Fixed burp sound not being played when a player eats food.
+- Fixed placement conditions for mushrooms - they can now only be placed when the light level at the target is <= 12, or on podzol or mycelium.
+- Fixed sign text appearing to change colour and/or glow when using dye on a sign - since this feature is not yet implemented, no change should occur.
+- Fixed players drowning when sprint-swimming on the surface of water.
+
+## Internals
+- Added more detailed debug logging during the player login sequence.
+- Silenced debug spam during `PreSpawnPacketHandler`, considerably reducing debug noise when players join.
+- Fixed an edge case in `InventoryManager->removeWindow()`. This bug didn't have any effect on stable versions, but caused a `next-minor` development version to crash.
+- `Item`s returned by event getters are now cloned if modifying the result will have no useful side effects.
+- Updated `pocketmine/bedrock-data` to [`1.11.1`](https://github.com/pmmp/BedrockData/tree/1.11.1%2Bbedrock-1.19.30), which reduces bandwidth consumption during logins by not sending useless biome generation data.
