As an initial rough publication to get everyone up and running, this release has been made supporting only modern versions of Minecraft Spigot and Paper.
This is read as 1.21+ on Paper and potentially still 1.20.5 supported on Spigot. Previous versions will be iterated upon in the official v2.0.0 release.

Due to differences in APIs and Paper beginning to drift away from Spigot - the APIs I use no longer support multi-version. I am still making design decisions on if I will use their Plugin-based variant for support or move forward with shading. I'm leaning to adding CommandAPI as a dependant plugin to allow faster lifecycles and reduced "I have to update it too" scenarios.
