Thunderbird Conversations
  • Thunderbird Conversations released. Thanks to everyone for relaying the news. This has been on Lifehacker, Reddit, GHacks, and various other websites. Lots of retweets.
  • A few comments on Twitter and the blog post. Went from 92 downloads/day to 1500. Statistics were initially pretty good, except there hasn't been a significant increase in the number of users as I expected. Low retention rate, I suspect people are afraid of Trunk.
  • Lots of bugs reported. Still a lot of open bugs. Managed to kill a few, the fixes are in the nightly versions.
  • Next: Andy and Bryan have some work to do and a few things to help me on, I think we can aim for a new release maybe before Christmas with mostly bugfixes in, or maybe next year.

Trunk (Miramar) Development

  • Landing OmniJAR today
  • Active branches.
  • Next Alpha: Early January.
  • Help on fixing blockers would be very useful and appreciated, see this list of higher priority bugs.
  • blocking criteria :
    • Alpha 1 -> Serious usability issues.
    • After -> not real criteria, regression/usability issues as usual.


  • Decision on if/when we'll do 3.2 on hold until we progress account provisioning further.

Thunderbird Stability & Security Releases

  • 3.0.11 and 3.1.7 released.
  • Planning to shut down 3.0.x nightly builds after Wednesday 15th, now that 3.0.x is end-of-life.
  • The wiki page on the process for landing security patches has now been made generic so that it applies to all security and stability branches.
  • Bug Lists: 3.1
Major updates to 3.1
  • -> 3.1.7 Major Update refresh this week.

Communication Channels

I (protz) just created a new wiki page Thunderbird/CommunicationChannels that lists all the communication channels we have. There's also a post on tb-planning. Please make sure you read the page (it's short) an add any items I might have forgotten. Once it's polished enough, we should probably link to this page from the official website, MDN, and other entry points for newcomers.

This tries to answer the concerns raised some time ago on mdat about the lack of communication. Update wanted for Thunderbird:Thunderbird_Post_3.1_Plan.
