Update The upgrade was done, DB migrations took around 5 minutes. We’ll keep an eye out for (new) issues but for now it seems to be OK.
Original message We will upgrade lemmy.world to 0.18.3 today at 20:00 UTC+2 (Check what this isn in your timezone). Expect the site to be down for a few minutes. ““Edit”” I was warned it could be more than a few minutes. The database update might even take 30 minutes or longer.
Release notes for 0.18.3 can be found here: https://github.com/LemmyNet/lemmy/blob/main/RELEASES.md
(This is unrelated to the downtimes we experienced lately, those are caused by attacks that we’re still looking into mitigating. Sorry for those)
Nobody said anything about posts. Activities could mean extra metadata like “someone joined”, “someone changed”, posted, edited, etc.
Most of the time, these isn’t required after a short while.
