1.21.5 is not yet supported, but when I try to start it I get the following crash log
It would be great if you could support 1.21.5.

There are so many changes with armor component tags related. but I don't have time to do it. probably we should wait for someone's pull request or until when I have time

Hey, I actually put together a quick port for 1.21.5. It's pretty bare-bones - just enough to run without crashing. I ported some rendering and armor calculation code, but hardcoded fixes for incompatible methods. Not thoroughly tested and definitely not perfect, but it works for basic usage. If you're desperate for a 1.21.5 version right now, you can have a try. No promises on further updates though.

I immediately tried it out.

I like the lack of enchantment animations.
