The footer still shows the old versions, by the way. It does feel snappier than earlier for sure.
I’m setting up my own instance to mess around with as well. I’ve got it running via Docker. The SSL setup was a pain, not really documented well. Also pictrs is giving me issues complaining about DB access.
The redirect is tricky and works in some browsers, but not others.
Edit: save took about 10 seconds, which is better than 20-30 seconds!
Edit 2: the footer shows the updated versions, now.
