I'd recommend sticking with the supported version, and filing a bug
report with the distro asking for a specific fix to be backported when
you have the need.

Regarding the upstream project, running a release is fine, but I
wouldn't recommend running the master branch in production. Important
details of new features can change before release, and with frequent
development it's more likely to have regressions.
