Lemmy's 0.19.6 introduces some bug fixes but it also introduced a nasty bug which breaks image rendering in many posts See here and since this instance hosts a lot of image based content it would probably be a good idea for us to hold off on upgrading until this is fixed. I do not know yet if this bug will apply retroactively, as in, if all posts made or affected by this will be fixed once a fix rolls out or if they'll be screwed up forever or until editing or re-posting.
I encourage people in instances which have not updated yet to cross-post this to their instance's meta community or ping their instance admins to let them know.
This might be a db0 issue tbh, here's that 196 post on .ml and slrpnk and it works fine.
The reason the AI posts works on previous versions is probably (I know nothing about how lemmy-ui works) because lemmy-ui sees a URL with an image extension and puts it in an
<img>tag, they must've stopped doing in 0.19.6 and stated using the MIME type in the API instead.It's not, it's still happening on the other instances, here's a different one on Lemmy.ml which isn't working, but is working here.
I think whatever that change they did was a bad idea, an example of trying to fix what isn't broken.
