It's been more than a month that we talked about regressions on the Thunderbird release channel in this article. So here is the next installment.
Careless refactoring in this bug caused a total of four regressions.
One of them, reported in bug 2040638, has clocked up 18 duplicates from affected users. The symptoms revolved around messages with attachments which caused failures when sending a or saving as draft. The second issue reported as bug 2050589 manifested itself in a stuck progress window, see article image.
Both bugs were fixed by Thunderbird's new star volunteer contributor while full time employees turned a blind eye or are enjoying their well-earned holidays. Needless to say that release channel users are still suffering as Thunderbird release management has not made the fixes available on this channel. Even on beta 153, only one of them was shipped. Both fixes are of course included in Betterbird's beta release.
