Bukkit

Added 1.17 version support

The plugin now supports version 1.17.

API update

The plugin api has been updated. Added new classes. The IUser class and all methods / fields associated with it are deprecated. The new class IPlayerData replaced the IUser class. Also, now you have to save the player data yourself using IPlayerData#save.

Bug fixes

Some bugs related to inventories have been fixed. Also fixed a few more minor bugs.

New features

You can now change a player's inventory after logging in, but after closing it, you will no longer be able to open it. Also added new opportunities for developers, namely, made it possible to change almost all NBT gamertags.

Other technical updates

Simplified the implementation of player data using abstract classes and helper classes that allow me to transform my NBT tags into NBT game tags. Also, now, every time you interact with the inventory, the result will be immediately reflected in the player's data, but saved only after the player has entered or the inventory is closed.
