XMir update for Ubuntu 13.10
Oliver Ries announces that while the Mir team is on track to support native Mir + Unity 8 running on Ubuntu Touch images, they not going to be able to deliver Mir + XMir + Unity 7 as the default experience on the desktop for the Ubuntu 13.10. Oliver says “Mir has made tremendous progress and is currently available on the Ubuntu archive for use, but there are still some outstanding quality issues that we want to resolve before we feel comfortable turning it on by default” and links to a Q&A for further information.
