No issues so far, everything I've tested works as expected (property tab complete, masking, regen, modifying selections). Not sure if we want to add the new (1.21.4) block types and stuff as well (just like WE does in their 1.21.3 draft PR) or release 1.21.3 as is

It's probably worth going for 1.20.3 first and then adding the .4 stuff as necessary

I noticed that the versions are somewhat inconsistent. We currently support 1.20.2, 1.20.4, 1.20.6, 1.21.1, and 1.21.3, right?

Could you also update the issue template?

The versions are pulled from the actual versions supported by our adapters:
1_20_2 -> 1.20.2
1_20_4 -> 1.20.3, 1.20.4
1_20_5 -> 1.20.5, 1.20.6
1_21 -> 1.21, 1.21.1
1_21_3 -> 1.21.3

1_21 -> 1.21, 1.21.1
1_21_3 -> 1.21.3

Yes, but e.g. https://github.com/IntellectualSites/FastAsyncWorldEdit/pull/2974/files#diff-c0dfa6bc7a8685217f70a860145fbdf416d449eaff052fa28352c5cec1a98c06R86 doesn't mention 1.20.2 (but 1.20.5, which is covered by 1.20.6 basically), and the issue template is not up to date.

I guess we could restrict supported versions to something like 1.20.4, 1.20.6, 1.21.1 & 1.21.3? would make the list more compact and skips a few updates which are not that widely used, I guess?

Yes, 1.20.2 should be added still, but otherwise just the latest version supported by the specific adapter version I guess.
