could you make version 5.1.0 available for Minecraft 1.20.1? all my mods are in this version

I'll most likely make a new 5.0 patch update that contains the bug fixes. They're pretty small so it shouldn't be too much work.

In general, I don't backport features (which 5.1.0 doesn't happen to have) as maintaining multiple copies of the codebase between Minecraft versions takes a lot of time (the same code doesn't always work in all versions).
