What version is that bug fixed in? It's not obvious from the bug report

Noting there is both 4.2.6 which we should probably at least upgrade to (point release), and then look at upgrading to 4.4 in the near future

Target Milestone: Bugzilla 5.0

by the looks.

I cannot upgrade to a not-yet-existing Bugzilla version. => INVALID.
If you want specific, identifiable upstream patches to get backported into the WIkimedia Bugzilla instance, please feel free to file an enhancement request. Thanks.

Yes at some point, but nothing urgent (no security issues fixed in 4.2.6), plus first https://gerrit.wikimedia.org/r/#/c/62404/ needs to get in (awaiting review). RT #5206

OK, just follow all the simple instructions on https://bugzilla.mozilla.org/show_bug.cgi?id=148564#c46

Thanks, but I've upgraded a Bugzilla before, so the required steps are known to me. Comment 5 still stands.
