Update:
At the time of writing, the following languages still need just the three new phrases to be translated:
Chinese (Traditional), Finnish, Greek, Hungarian, Latvian, Lithuanian, Norwegian, Portuguese (not Brazilian), Romanian, Turkish.
These languages are missing more than just the three new phrases and are in varied states of completion:
Arabic, Bulgarian, Hebrew, Thai.
If you know someone able and willing to help out, give them a poke and direct them here.
