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)

Any idea if 18.3 will be able to provide more security?

This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%. Special thanks to @phiresky for their work on DB optimizations.

The federation code now includes a check for dead instances which is used when sending activities. This helps to reduce the amount of outgoing POST requests, and also reduce server load.

In terms of security, Lemmy now performs HTML sanitization on all messages which are submitted through the API or received via federation. Together with the tightened content-security-policy from 0.18.2, cross-site scripting attacks are now much more difficult.

A website which should let you check what time that is for your local time zone; although I used Central Europe Summer Time (CEST) instead of Central Europe Time (CET) and I'm not sure if that's right.

Thanks for your amazing work as always!

Will calckey.world be renamed as well, as upstream abandoned the calckey name?

[-] Coelacanth@feddit.nu 4 points 1 year ago

I'm curious about this as well. I've looked into Firefish a bit and it looks interesting, but I can't seem to follow Lemmy communities from the flagship instance Firefish.Social.

Works on calckey.world, though.

[-] ruud@lemmy.world 4 points 1 year ago

Calckey.world also runs Firefish 1.0

[-] Coelacanth@feddit.nu 3 points 1 year ago

Firefish.social was upgraded to 1.0.something yesterday I believe. Maybe something broke? On Firefish.Social trying to follow a Lemmy community ends up in just an endless spinning wheel and "processing" while it works normally on calckey.world.

Curious.
