I’m sure many have that problem right now (e. g. feddit.de is on 0.17.4), and I understand the developer’s choice not to support old server versions anymore, so when I choose to stay with Jerboa 0.0.34 for the time being, I’d at least like to see when my instance upgrades to 0.18. I can see it at the bottom of the Communities list in the desktop browser, but haven’t found it in the app, yet.
Immediately jumping to each new server version and not supporting the previous one is bewildering. Admins need time to vet “upgrades” and do the actual work. Lemmy isn’t one central site. Things move at different speeds and app devs need to take that into consideration.
