Taking opportunity of the near release of 1.21.5, i want to ask if there is plans to both update the mod to newer versions and if eventually a port to Fabric can be a reality.

If not, can other mods interested do a PR for update/ports?

Hey!
We'll be working on a port to NeoForge for 1.21.5 very soon, however we currently have no plans to make a Fabric port. Feel free to work on one yourself!
