Release 3.11.1

there are no protocol changes in 1.14 that matter; the reason the protocol version has been bumped is because of new blocks, items, mobs and recipes.

+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.
+
+**WARNING: If your plugin uses the protocol, you're not shielded by API change constraints.** You should consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you do.
+
+# 3.10.0
+- Added support for Minecraft: Bedrock Edition 1.13.0
+- Removed compatibility with 1.12.0
+
+## Note about skins
+PocketMine-MP **does not support skins made in the Charactor Creator** (known as Persona skins), due to technical changes which would require premature backwards compatibility breaks. The dev team has decided not to support Persona yet.
+These skins will be **replaced with a random solid-colour skin. This is not a bug.**
+Skins chosen from the Classic tab (classic skins) will continue to work as normal.
+
+# 3.10.1
+- Fixed custom plugin-created skins being invisible when no geometry name was specified.
+- Updated RakLib to 0.12.6 to fix security bugs.

 - Fixed some issues with multiple consecutive commas inside quotes in form responses.
 - Fixed server crash when the manifest json does not contain a json object in a resource pack.
 - Ender pearls no longer collide with blocks that do not have any collision boxes.
+
+# 3.9.6
+- Updated Composer dependencies to their latest versions.
+- Prevent clients repeating the resource pack sequence. This fixes error spam with bugged 1.12 clients.
+- `Internet::simpleCurl()` now includes the PocketMine-MP version in the user-agent string.
+- Spawn protection is now disabled by default in the setup wizard.
+- Default difficulty is now NORMAL(2) instead of EASY(1).
+- Fixed crashing on corrupted world manifest and unsupported world formats.
+- Fixed `/transferserver` being usable without appropriate permissions.
+- `RegionLoader->removeChunk()` now writes the region header as appropriate.
+- Fixed performance issue when loading large regions (bug in header validation).
+- Fixed skin geometry being removed when the JSON contained comments.
+- Added new constants to `EventPacket`.
+- Added encode/decode for `StructureTemplateDataExportRequestPacket` and `StructureTemplateDataExportResponsePacket`.
+- Fixed broken type asserts in `LevelChunkPacket::withCache()` and `ClientCacheMissResponsePacket::create()`.
+- `types\CommandParameter` field `byte1` has been renamed to `flags`.
+- Cleaned up public interface of `AvailableCommandsPacket`, removing fields which exposed details of the encoding scheme.
+- Improved documentation for the following API methods:
+  - `pocketmine\item\Item`:
+    - `addCreativeItem()`
+    - `removeCreativeItem()`
+    - `clearCreativeItems()`
+  - `pocketmine\level\Explosion`:
+    - `explodeA()`
+    - `explodeB()`
+- Fixed various cosmetic documentation inconsistencies in the core and dependencies.
+
+# 3.9.7
+- Fixed a crash that could occur during timezone detection.
+- Squid no longer spin around constantly in enclosed spaces. Their performance impact is reduced.
+- Cleaned up the bootstrap file.
+
+# 3.9.8
+- Added [PHPStan](https://github.com/phpstan/phpstan) configuration. PHPStan is now used on CI for automated QA, which should improve stability and quality going forward.
+- The following constants are now autoloaded when loading the Composer autoloader:
+  - `pocketmine\NAME`
+  - `pocketmine\BASE_VERSION`
+  - `pocketmine\IS_DEVELOPMENT_BUILD`
+  - `pocketmine\BUILD_NUMBER`
+  - `INT32_MIN`
+  - `INT32_MAX`

+- Fixed crashes that could occur when tile classes were overridden with classes incompatible with the originals.
+- Fixed improper handling of non-Compound root NBT tags on network itemstack decoding.
+- Fixed paintings dropping multiple items when destroyed by block updates.
+- Fixed `var_dump()` not showing private and protected properties of `DataPacket` subclasses.
+- Fixed overloads with zero arguments being missing when decoding `AvailableCommandsPacket`.
+- `CraftingDataPacket` now retains the `cleanRecipes` field when decoding.
+- Fixed `Block->getMetadata()` returning null (non-iterable).
+- `PlayerChatEvent` documentation has been updated to specify that `CommandSender` recipients are accepted. This behaviour was already present in previous versions, but incorrectly documented.
+- Fixed various issues with PHPDoc comments reported by PHPStan.
+- Fixed various minor code nits reported by PHPStan.
