hg.mozilla.org system updates this week

[Gregory Szorc]

We'll be performing a number of updates to the systems behind hg.mozilla.org
this week, including upgrading the version of Mercurial that is deployed.

If you see any unexpected behavior with anything connected to hg.mozilla.org
this week, please make noise in #vcs or #moc on IRC, as it could be related.

[Gregory Szorc]

Over the past ~week, we've performed numerous upgrades to hg.mozilla.org.
The ssh://hg.mozilla.org/ endpoint was upgraded from Mercurial 4.2 to 4.3,
then to 4.4, then to 4.5. The https://hg.mozilla.org/ endpoint was upgraded
from 4.4 to 4.5 a few minutes ago.

As part of the change, various extensions in version-control-tools received
compatibility updates. If you haven't updated version-control-tools in a
while, now would be a good time to do so.

As of today, the infrastructure is current per our upgrade policies (we
wait until the X.Y.1 point release to upgrade to a new major version).
4.6.1 should be released in the next ~week, and we will try to upgrade soon
afterwards.

If you notice anything strange or wrong with the behavior of hg.mozilla.org,
please make noise in #vcs and/or file a Developer Services :: hg.mozilla.org
bug.
