Release notes: https://github.com/LemmyNet/lemmy/blob/main/RELEASES.md
TL;DR it’s faster, the database is smaller (my DB backups went from 3.5GB to 570MB!), and it’s more secure.
Messed up a simple config and it took about an hour to get the site back up instead of 10 minutes as I had thought. Sorry!
Welcome! What made you pick this instance?
I like the general community guideline (regular Lemmy logo, regular Lemmy URL, regular UI, etc…)
