Some time in the next week, the #spectrum:libera.chat Matrix room is
going to stop working, as a result of a dispute between Libera.Chat and
matrix.org[1].
So, unfortunately, if you want to keep using Matrix to participate in
the Spectrum chat, you need to take some action:
1. Leave #spectrum:libera.chat
2. Join #spectrum:fairydust.space
It's very important to do it in that order, because otherwise the bridge
gets confused and bad things happen.
If something goes wrong, rejoin either channel, ask for help, and we'll
figure it out.
On the positive side, the new Matrix room is controlled by me, rather
than by the administrators of the Matrix-Libera bridge. This means we
can have nice things like room history, and if something like this
happens again (needing to use a different bridge, moving IRC network,
etc.), I should be able to use my room admin powers to change the setup
transparently, without any action being required from individual Matrix
users. So this is hopefully the last time I'm going to have to ask
Matrix users to join a new room.
