systemd enabling cgroup v2 by default (default-hierarchy=unified)

Lukas Märdian tells us Ubuntu will be following upstream and "switching to the 'unified' cgroup hierarchy (cgroupv2) by default". Mentioning issues that may occur with snapd, mitigations are in place to deal with them (with more coming later in the cycle). Many links are provided for more details.

Call for testing: 20.04.3 release candidate images ready!

Łukasz 'sil2100' Zemczak of the Ubuntu Foundations team tells us the critical blockers have been resolved so Ubuntu 20.04.3 point release RC images are ready for testing. We're invited to pick our "favorite flavor and start testing" reporting results on the isotracker. Links are provided.

Impish Indri (to be 21.10) now in Feature Freeze

Iain Lane, on behalf of the Ubuntu Release Team, reminds everyone that "as per the release schedule, Impish Indri is now in Feature Freeze". The focus now should be on bug fixing, with a link provided on freeze exceptions if required.

Migrating glibc 2.34

Michael Hudson Doyle tells us glibc is in impish-proposed now, with the autopkgtests completed, however due to a number of build failures it cannot migrate. This thread keeps track of the status on fixing those failures.

Background info from the Media:

This is the Way - the Ubuntu Code of Conduct

Monica Ayhens-Madon writes about the Ubuntu Code of Conduct. We are first reminded that a new easier way to sign will be introduced, but the purpose of this post is to "chat about the code itself - at least the first section of it". Monica walks us through some of the code, and provides some of her thoughts and reactions, before inviting us to join in this discussion about the code itself, and possibly improving it, or at least keeping it a 'living document'.

About the Membership category

This is a placeholder created by Rhys Davies, for "all conversations and applications for and about becoming an official Ubuntu member".

Vote in the Ubuntu 21.10 wallpaper competition

Rhys Davies tells us that this wallpaper competition has had over 200 entries and thanks all entrants. Rhys then moves to how voting is being performed, with links and a reminder that you have until 27 August 2021 to cast your ten votes on which you consider the best. An apology is also made for the low quality images on the vote-casting website, with a request for alternatives for the next 22.04 cycle to be presented.
