Thunderbird 3 Plans for 2008

Posted: January 28, 2008 in Blogs, General Thunderbird, Thunderbird 3 (Shredder)

David Ascher head of the newly formed MailCo has posted plans for Thunderbird 3. The main plan is to increase the already sizable user base (millions) by including with Thunderbird 3 built-in calendar integration (based off of Lighting) much like Microsoft Outlook. Also to introduce a better search function such as those found in Gmail or In addition to these plans is the goal is to have a final release of Thunderbird 3 by the end of 2008. Here is an overview of David’s plans for Thunderbird 3 in 2008:

  • Goal:

    • To have at public milestone build of Thunderbird 3 in 2008.

      • Thunderbird 3’s overall aim is to significantly grow its user base worldwide, as well as build a strong foundation for later Thunderbird releases.

  • Release-defining features:

    • an integrated calendaring feature, based on Lightning
    • a better search experience, especially for message content searches
    • a better overall user experience

  • Less user-visible but important goals include:

    • Significant headway on getting rid of Mork and RDF
    • A concerted effort to improving the extensions ecosystem for Thunderbird, including refactorings, FUEL, developer documentation, and user experience
    • Better test coverage and performance metrics in place to support refactoring goals

  • Schedule

    • Figuring out the schedule at this stage is hard, as it will depend on who shows up with energy and talent. I would like to set some placeholder milestones for discussion, however:

      • Alpha builds in Q1
      • Beta builds without calendaring starting in Q2
      • Widely useful builds by Q4 (although whether they’re branded “release” will depend on quality, as always.
      • We’re revise the schedule as we gain knowledge.

It is important to understand Thunderbird 3 will not be the end of Thunderbird. Planning for Thunderbird 4 will be beginning soon and will included features that were not possible to be part of Thunderbird 3 due to the aggressive build schedule. But with that said, tabbed browsing/navigation is a planned feature for Thunderbird 3 (however, t was for Thunderbird 2 as well).

There is quite a bit of information on the Thunderbird 3 Mozilla Wiki Page.
