What a wonderful release! High fives all around! Since I got a other kid I have only really done 2 things, a little bit of goof loop (https://git.sr.ht/~bjoli/goof-loop) and the patch to make define valid in more situations. I didn't even know it was merged, but I am glad I was able to contribute something :)
