I think this would be well worth mentioning in the changelog. Just to give one reason: the changes to the profile folder from the 78.x to 91.x series are irreversible. Once a profile has been opened with the 91.x series, even after re-opening with 78.x and --allow-downgrade the local mail account is unreadable. As best I can tell, the mail isn't actually deleted, it's just invisible to the profile configuration, but you can't get it back without potentially corrupting the entire profile. Moreover, at some point in the 78.x series setting up a new movemail account became impossible, so the most expedient recovery method is unavailable.
This means users with a Thunderbird movemail account will permanently lose access to that account unless they have a full profile backup to restore from. I think most folks would agree this counts as a regression that has the potential to result in data loss. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946606 Title: thunderbird 91 does not support movemail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1946606/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
