Thunderbird 38 goes to beta!

The next major release of Thunderbird, version 38, is now in beta and available for testing. You may download Thunderbird 38.0b1 here.

This version of Thunderbird is the first that is mostly managed by volunteer community members rather than by Mozilla staff. We have many new features, including:

  • Message filtering when a message is sent or archived
  • File-per-message local storage available for new accounts (maildir)
  • Contact search over multiple address books
  • Internationalized domain names for RSS feeds
  • Allow expanded columns to the folder pane for folder size and counts

Release notes are available here.

There are still a couple of features missing from this beta that we hope to ship in the final version of Thunderbird 38. Those are:

  • Ship Lightning calendar addon with Thunderbird with an opt-out dialog
  • Use OAUTH authentication with Gmail IMAP accounts

    How stable is maildir? Is it possible to transfer existing accounts to maildir?
    I have work account with arround 60.000+ messages in around 20 folders. Would test beta on it, but I’m afraid it will break something. 🙂

      The nature of betas is that there is an increased risk of it breaking something.

      As for maildir, there were a number of serious issues in maildir in Thunderbird 31 that should be resolved in Thunderbird 38, including this beta. I personally use all maildir on my Thunderbird profile, but that is dogfooding. There has not been extensive testing of this, so if is good to be cautious. There are no known serious issues that would preclude its use, and mbox has its own issues. But we would not make it the default for most users because of lack of testing.

      There is no method to update existing accounts. To switch to all maildir, I created a new profile and reinstalled all of my accounts.

    I would beg you guys to please, please consider implementing ‘Option to use same credentials for outgoing as incoming’:

    And since it is by far the most common case, I would make it the default.

    Thanks, looking forward to testing TB38, as it looks to be a really fantastic release!

      Note: I approved this comment, but in general this is not a good place to advocate for particular bugs, so in the future I will probably not approve similar comments.

    So, they are jumping to v38 to match up with Firefox? The current version is 31.6.0, correct?

    1. kent wrote on :

      Thunderbird only does major releases following the Firefox ESR schedule, so the last was 31, the upcoming is 38, and the next after that will be 45. Yes 31.6.0 is the current release.

      I am on record as saying I don’t like this number jump, and I have proposed that we start naming our major releases after bird species. Under this proposal, 38 would be “Avocet” and 45 would be “Bunting”. This is still in discussion however.

    Finally Maildir support! No more +100GB mbox files corrupting… Easier backups, mutt integration! Yay, makes me happy!

    1. kent wrote on :

      The easier backups are certainly real, but Mutt integration was never a goal, and is not likely to work with our implementation of maildir.

        Why wouldn’t it work? Is there something specific to your format, or do you just mean that it won’t work when both TB and Mutt are started at the same time?

        1. kent wrote on :

          First, Thunderbird relies on an index of messages, so any changes to messages that occurs outside of Thunderbird would not be picked up by Thunderbird.

          Second, since compatibility with other applications has not been a goal, no attempt has been made to insure that our file-per-message format is compatible with other programs, so things like how folders are represented probably does not match other programs. That said, testing with other programs has not been done, so the compatibility is unknown.

    I’m not really sure where I read this. However, is it true that Thunderbird 38 has support for WebRTC? Will Thunderbird integrate Firefox Hello? I am really looking forward to this 🙂

    1. kent wrote on :

      In our plans for this release, we were hoping that chat would have WebRTC ready for this release. But that did not work out, so it is not included.

      As for Firefox Hello, the Hello team says that Hello is pretty dependent on Firefox, so they did not think it would make sense to merge it into Thunderbird. That sounded like a good idea to me as well (particularly using the address book in Thunderbird) but it has not been investigated any further, and there are no current plans to pursue this.

      1. Aldioooo wrote on :

        Integration of WebRTC would be superbe. With regards to the inclusion of Firefox Hello, this would be really a great addition!

        For any reason, people are using Skype and reluctant to use something else. However, the acceptance of using Firefox HELLO has been great over the past weeks/months. I was absolutely surprised. Hence, the integration into Thunderbird and its address book would be just fabolous.

        This would also be great for the reason that many people do not use Firefox as their browser, but they use Thunderbird everday. Hence, this also increases outreach of HELLO, particularly in academic and business environments.

    I heard somewhere on Internet that Thunderbird was freezed in 2012 and new features were not being developed. But this version has new features which means it’s unfreezed now!
