@SkyzohKey it needs tests. There are a few PRs merged in 0.2.2, so we'll release this version now.

@zoff99 @robinlinden do we need #841 in 0.2.2?

[zoff99]

@iphy no

Can we switch groupbot to use persistent groups? That way more people will be able to test it easier. Tens of people use groupbot every day, so we could ask some of them for help with testing.

blocked by #872

Also blocked by the autotools build being broken in master. You will want to cherry-pick this commit that fixes it before making a release 90202a1. It's part of #867 but I see that that PR might not make it in 0.2.2, so just cherry-pick.

It would also be nice to get #875 in before the release, so that we could see if bootstrap node maintainers update the nodes after we ask them over the mailing list to update. It's not a required PR though, feel free to skip it.

The release will be without #867 as I can't merge unsigned commits and I can't push to forks based on irungentoo's Toxcore repository. I've cherry-picked the commit fixing the autotools build. There's still lots of discussion going on in #875 and it shouldn't block the release, so that PR will have to wait too.
