Gerrit has released a 3.8.3 bugfix release. The release notes cover the
changes [0] made. In addition to the listed changes we should also pull
in a bugfix for change submissions failing due to a null account field
in metrics gathering. The reason for this is we actually build
stable-3.8 and not off of the 3.8.3 tag and this bugfix was included
after the bugfix release. Basically we build latest stable rather than
the tagged release.
We should probably keep an eye on general performance as we may need to
modify cache maxAge and refresh settings due to these being honored by
persistent caches now. Otherwise this update should be pretty
straightforward.
