Currently our bugzilla instance seem to be sitting on the 4.4.x series release
-- I can't figure out what exact version --, and missing out features, bug
fixes and performance improvement, among other things, I presume. At this
moment the 4.4.13 (from February 16, 2018) version is the old stable release
[1], while the 5.0.6 (from February 09, 2019) is the current stable release.

I know that there should be a SUSE team that purely oversees the infra side of
bugzilla and another that takes care of the software itself (Legacy Application
team?). Can anyone shine some light on why haven't our instance been updated to
the current stable release yet?
