System messages can no longer be customized. They are fixed in code and unchangeable.
The plugin is now in English by default.
The setting responsible for checking for a new version of the plugin has been redesigned and disabled by default
Added server version checking: 1.13.2 and higher (during the check the player will stand exactly in the center of the block) and 1.13.1 and lower (the player will be on the edge of the block, I have not found a solution to this problem, so far)
Fixed a problem where the plugin did not start on some versions (For example 1.13)
Protection against emergency server shutdowns now works correctly
Some dev. notes:
Comments have been added to the code in some places
The code has been improved in some places (thanks LEDev)
