Public bug reported:
In mailman 3.0.0a8, the locales directory contains actually mailman 2 translations. The unsubscribe mail is not translated into French because the msgids are different between mailman2 and mailman3.
Do you have a script to generate a pot file and sync the po files?
I had to generate myself the French mo file from the po. It's maybe a good idea to include mo files in the sdist, or generate mo files at mailman startup.
