TotalFreedomMod Electrum

Version 5.0

This TotalFreedomMod release implements many changes. Most notably, the
internals have been completely revamped. TotalFreedomMod now relies on the
Aero library for core mechanics such as command handling and services.

Another important change is the UUID system. In TotalFreedomMod Electrum,
it has been completely removed. The core reason for this is that the
system as a whole was very bugged. Additionally, it did not solve the
primary reason for its conception: preserving player data when the player
changes their username. This is because TotalFreedomMod servers usually
run in offline-mode. This meaning that some of the players joining do not
have a registerd Mojang UUID whatsoever. All in all, the UUID system was
buggy, and it did not fix the reason it was implemented, so it has been
completely removed. The admin list and the ban list now use usernames and
IPs again.

Lastly, many smaller changes have been implemented. Due to the amount of
changes, they have not been named individualy. Please refer to the issues
below for more details.
