Welcome to the latest version of Lemmy!

Version 0.19.5 is a minor release with some bug fixes for 0.19.4. We were never running 0.19.4 so the bug fixes are less important than that new features in 0.19.4.

Release notes for 0.19.4 are here.

Release notes for 0.19.5 are here.

The upgrade took a bit longer than expected, perhaps 40 minutes of downtime. Partly this is because of an issue with postgres memory that happened before I started the actual upgrade.

Probably the two biggest new features for users are the ability to hide posts, and the ability to see any images you've uploaded (since lemmy started tracking).

There is also a new setting to change how upvotes are displayed, and we have a new option to have communities that don't federate. Maybe this community is a good target for that? Let me know your thoughts.

Let me know if you have any questions or see any strangeness!

It was actually to do with docker rather than postgres itself. Docker limits shared memory to 64MB, and postgres died when it couldn't allocate more. I saw this in the test server as well, but I didn't want to assume so I waited to see it in production before applying the fix.

The error was something about failed to allocate disk space, the solution was to add shm_size: 1GB to the docker compose section for lemmy's postgres.
