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.
