First commit: https://github.com/FascinatedBox/lily/commit/1e509cbdd56ef36...
Commit list at oldest page: https://github.com/FascinatedBox/lily/commits/master?after=9...
(GH doesn't seem to have an easy way to jump around time and directly find commits. I jumped to the oldest tag, went to the commit list, clicked "older", edited the tag out of the URL then followed "older" to the start. Took around 15 clicks.)
