Just wanted to loop everyone in to the bugs/issues that have been discovered so far with 0.19. I'll try to keep this updated, however if you notice any others please put them below.
We're experiencing most of these (except the outgoing federation one AFAIK, I've not had it reported).
We are especially suffering from the high server load one, and you may see downtime where Lemmy.zip is not loading for short periods (or the message "lemmy is starting") while the DB restarts itself. This should only last a couple of seconds.
To mitigate this, I've temporarily upgraded the performance of the server so this should happen less frequently (once a day instead of once an hour!) but I do sincerely apologise. With any luck this will be fixed soon.
