I have now upgraded the Divisions by zero to Lemmy 0.19.0. I haven't seen any issues, but of course you will have to re-login.
Please check the new features here
I have also updated Pythörhead to be able to handle the new authentication (as well as the old), so if you're running a bot, make sure to update your Pythörhead dependencies.
Now is also a good time that you can support the running of this server. If you just want to support this instance, please use Ko-fi and you can get a custom emoji here. If you want to support my general development efforts as well (Lemmy, Pythorhead, Fediseer, Tagginator etc) feel free to use my liberapay
There may possibly be some issue with outgoing federation as noticed by this commenter: https://lemmy.ml/comment/6690834
In fact, it seems comments from lemmy.ml haven't been federating since 4 days ago. Just check some active lemmy.ml accounts.
e.g.:

https://lemmy.dbzer0.com/u/dessalines@lemmy.ml?page=1&sort=New&view=Comments
I am not entirely sure if it's something to do with 0.19, but my home instance, lemmy.sdf.org is also having issues with outgoing federation since upgrading to 0.19.x, although it's currently still just on 0.19.0-rc.13. That's also why I am writing this from this account instead.
Is there a reason some instances wouldn't be federating correctly and others would?
I don't know. But there's already an issue about it: https://github.com/LemmyNet/lemmy/issues/4288
Also, the federation used to work on SDF after each upgrade for like 3 days, so it may or may not break later.
