TrimMe2 1.3.0

From now on, I'll prioritize updates for latest versions of Minecraft, but keep old versions alive still. Whenever anything that can break the datapack/resourcepack between versions I'll consider it a before/after, so the afters will get the updates! Cheers.

Datapack:

• Updated pack.mcmeta to include 1.21.11

Resourcepack:

Min version is now 1.21.11

• Updated RP to 1.21.11
• Fixed changes to Atlases.
