Release 3.11.2

I do not think that this bug is in effect in the core code, but I can't be sure.

+**For Minecraft: Bedrock Edition 1.13.0**
+
+### 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.

+- Removed compatibility with 1.13.0
+
+# 3.11.1
+- Fixed blocks with incorrect properties when placed or interacted with.
+
+# 3.11.2
+## Core
+- PHPStan 0.12.3 with level 5 is now used for automated static analysis.
+- Fixed a possible crash when plugins override the `EnderChest` tile class with something incompatible.
+- Fixed disconnected players being considered as never played.
+- Fixed enchantments with IDs outside the range 0-255 in item NBT crashing the server.
+- Fixed particles rendering incorrectly.
+- Timings handlers are no longer able to underflow; they now throw exceptions when attempting to be stopped more times than they were started.
+- Fixed explosion rays getting stuck in empty subchunks (possible incorrect behaviour in large caves).
+- Fixed bad tile/entity NBT data being propagated from world providers in some cases.
+- Fixed a possible crash when detecting timezone on CentOS.
+- Fixed many cases of incorrectly documented types in the API found by PHPStan.
+- Generation tasks no longer assume that generator instances stored in TLS are always valid, fixing a possible crash.
+
+## Protocol
+- Fixed skin animation image corruption in LoginPacket handling caused by incorrect data handling.
+- Fixed skin animation extra data not being decoded from LoginPacket.
+- `SkinImage` now throws `InvalidArgumentException` if it receives an unexpected amount of bytes for the given image heigh/width.
+- Fixed broken code in `PlayerAuthInputPacket::create()`.
+- Removed some dead constants from `NetworkInventoryAction`.
