Hi, I made a Fabric Minecraft mod called Ambient Leaves.

I want the mod to support multiple Minecraft versions, such as from 1.20 up to the latest versions like 1.21.12. Right now, it only supports versions 1.21.1–1.21.8.

Is there any way to make a single mod JAR support multiple Minecraft versions, or do I need to create separate JAR files/builds for each version?

1.21.12 isn't a real MC version

#

and yes you're going to have to make separate jars

#

not sure how you didnt infer that from other mods
