Ubuntu developer discussion moving to Matrix

Ubuntu will be moving its 'official realtime communications
channels' from IRC to Matrix, beginning March 1, 2025, following
a discussion
on the ubuntu-devel mailing list.

'Official' communication, such as making realtime requests of privileged
Ubuntu developer teams, could be expected to be actioned if requested on
Matrix only. Similarly, you can consider your social responsibility to
other developers in relation to your work in Ubuntu development to be
fulfilled if you are present on that platform. And Canonical will
follow in its requirement for its employed Ubuntu developers to be
present on that agreed platform during their working hours.
