Hi Florian,
Your turn for the "last chance to tag things for 3.1" email now that Aurelien's weighed in. ;) (I'm cc'ing the rest of mailman-developers in case anyone else wants to advocate for a bug too...)
I *think* we've got 3.1 tagged appropriately, which means that the unicode bug is the last big one, and I'd like to get the default preferences fixed for good (currently they display correctly but can't save). Do you have anything else that we should look at before we push out RC1?
Also, if you have a chance, can you look at https://gitlab.com/mailman/postorius/merge_requests/159/
I put a question about address-based preferences and mailmanclient in there for you, but I could also use a second look for "what's the best way to fix it so these save properly?" if you have a chance. I've broken the django magic and need to override the save method I think.
Terri
