This upgrade is now complete. I see a few immediate clumsy spots in the
GUI that I'm going to work on ironing out today, but everything should
now be usable. Let me know if you run into trouble!

Tomorrow I'm going to upgrade https://horizon.wikimedia.org/ from
version 'Liberty' to version 'Mitaka'. I've scheduled an hour-long
window for the upgrade, although the actual switch-over should be much
shorter. Downtime should be minimal; I'll be clearing caches as part
of the upgrade, so login sessions will be interrupted, and performance
may suffer a bit while the cache is cold.
The Mitaka version contains a lot of new Javascript front-end
code. Some of the new interfaces (in particular the one for creating
new VMs) are a bit strange and will take some getting used to.
Overall, though, the Mitaka upgrade is an improvement, and I have high
hopes that it will considerably improve performance.
I've tested the new version extensively, but there may well be
breakages around the corners of some of our custom features, so don't
hesitate to notify me if you see new, bad behavior.
