We've shipped Betterbird 140.5.0esr-bb14 today. Please refer to the Release Notes for full details.
We've addressed issues reported by users in the last four weeks.
The Betterbird-native new mail alert on wrong monitor issue is finally fixed, and preference mail.notification.show_on_app_screen should also be working now. We revived preference mail.folderpane.sumSubfolders which had become a victim of Supernova-Kaboom in Thunderbird 115.
Users of the Proton Mail Bridge can now unsubscribe from the likely unwanted so-called "no-select" folders Labels and Folders after setting preference mail.imap.allow_unsubscribe_noselect.
The pesky calendar scroll issue when switching tabs was also fixed by advancing a Mozilla patch. We're also advancing eight bug fixes which are not shipping in Thunderbird 140 ESR yet. As far as providing recent bug fixes to ESR users is concerned, Betterbird is about 50 fixes ahead of Thunderbird.
Finally, the "Recent Destinations" menu was returned to its original state of only showing folders to which messages had been recently moved, the sort order is now based on latest use.
