For Minecraft PE 0.16.0.5 alpha

THIS IS A PRE RELEASE. Do not use it in production unless you are sure you know what you are doing.

Only changes since the 1.6dev tag will be documented here. Changes between 1.4.1 and 1.6dev are far too extensive to document effectively.

Changes

Core

• New RNG, based on XorShift128 from the php-random library. This fixes issue with repeating terrain on 32-bit systems. Note however that new generation into existing worlds will not be seamless.
• Block and Item IDs have been moved to interfaces for better consistency
• Better method for synchronisation of client/server time (less packet spam)
• Utils::getRandomBytes() has been deprecated in favour of php7's random_bytes() function.
• <player>.dat saving/reading can now be disabled in pocketmine.yml (set player.save-player-data to false)

Gameplay/game features

• Added Flower Pots
• Containers can now be opened in creative
• Trapdoors can now be placed without a supporting block

API

This release has API changes, bumping the version to 2.1.0.

Entity metadata (0.16)

Many changes have been made to entity metadata. Many true/false data properties are now entity status flags, such as NoAI, NametagVisible and various others. Entity status flags can be set using:
$entity->setDataFlag(Entity::DATA_FLAGS, Entity::INSERT_DATA_FLAG_NAME, true/false);

Breaking changes are detailed here. Additions are not documented. https://gist.github.com/dktapps/76b291b7a861762b54f7a8b834389883

NOTE: It's strongly recommended to use provided API methods where possible instead of tampering with metadata directly.

AsyncTask API additions

• Main thread local storage: Developers can pass any data including objects to the constructor of AsyncTask such that the data can be retrieved after the AsyncTask completes using the new AsyncTask::fetchLocal() method, or use the AsyncTask::peekLocal() method to get the data without removing it.
• Progress updates: Developers can use the new AsyncTask::publishProgress() method and overrideAsyncTask::onProgressUpdated()` to handle AsyncTask progress information in the main thread.

Refer to #1 and #100 for details.

WeakPosition

WeakPosition was added in 1.6.1 to fix bugs with unloading levels which have player spawn points set in them. This type of position holds a level ID instead of a direct reference. Use this when your position may outlive the level it is in.

Removal of Item/NBT circular dependency

Refer to #121 for details.

Other

• Added Player->sendWhisper() (#73).
