uSkyBlock traces back to the skySMP plugin, which was licensed under GPLv3, and to rlf/uSkyBlock, an earlier continuation of Talabrek's Ultimate SkyBlock work.
For a time, public continuation of the project was difficult because the Bukkit listing was registered as All rights reserved, which complicated sharing and maintenance even as community interest continued.
At the end of 2014, Talabrek explicitly gave his blessing for this repository to continue the project and consolidate the different community branches into a single, officially maintained uSkyBlock codebase.
