I've set up a test instance of lemmy with a recent backup restored (backups are each over 200GB because of the image cache) and am preparing to test the update to lemmy 0.19 and pictrs 0.5.

I'm thinking I might do the 0.19 first, then once others have updated to pictrs 0.5 and it's going OK then I'll give it a go in the test instance. The pictrs update is what I've been waiting for, which let's us set an expiry of the image cache (currently lemmy had all images ever cached still in the cache, in full resolution).

The lemmy 0.19 update shouldn't take long, but the pictrs one will take a while I believe as it's got some sort of database migration to do.

Anyone got any objection to having lemmy.nz updated to 0.19 later this week? It might break apps that haven't been updated in a while, but that is inevitable anyway.

Update: I've run the 0.19 update in my test environment, all is working. It took a little over 20 minutes from starting it to having the site back up and available again.

I might do an evening update. I'll make an announcement post and people can post their objections or ask their questions there.

Update 2: I won't do the update today, there are some other instances still having serious problems.

Good news about 0.19! I read that it's more resource intensive somewhere, not sure if it's true.

Hmm, it's supposed to be less 😆.

No matter, I'm most exciting for the pictrs update that lemmy uses for storing images. Daily backups of 200GB+ and growing are beginning to be a bit of trouble to transfer and store. I've been hand holding the backup process recently.

I don't think the pictrs 0.5 update is officially released yet, but when it is our backups should be significantly smaller (as well as the general disk usage).

One exciting thing for 0.19 is that the issue should be solved where it loads the wrong page when you press the browser back button.
