dbuc is shooting a new tutorial video this week: let him know if there's any particular material that should be included.
SDK
we made another hotfix release: 1.4.3. Blogged it, drafted a press release.
lessons learned? It's a worry that this bug was present for a while before we noticed. Our tests don't test that persistent storage isn't broken across releases. We can improve our testing here, and it would help a lot if we have more aggressive/widespread testing of our betas. We'll talk about this during the work week.
we'll spin a 1.5 Release Candidate today. Builder should take it, because the 1.5b3 it is currently using does not have the 1.4.3 fix in.
lots of people want the SDK to work with Thunderbird. Ochameau opened a bug to help with this, and whimboo started work on the SDK. He's keen to get MozMill and other add-ons working with the SDK.
we don't have the resources to officially support Thunderbird. However, we can at least not intentionally break it by throwing exceptions.
it's not possible to pass XML between compartments without explicitly serializing it. We should raise a bug so we can at least find out why this is so.
