at we have, and when we received all .po files pertaining to it,
we just release a 4.9.1 with those. We might have bug-reports and
fixes in the mean
time as well, so it is never a bad idea to have an x.y.1 release
shortly after the x.y.0 release.
We could even adopt that as a policy for future releases. String
freezes are just not practical;
it is always better to have an item with an untranslated name in the
UI than not having
the item at all. Or postponing the release, leaving people with
unfixed bugs in the previous
version.
