According to the announcement in <http://groups.google.com/group/mozilla.dev.apps.thunderbird/msg/5396616f6252b4d6> the openTab API will be changed with Bug 467768. It should be checked if Lightning requires update: http://mxr.mozilla.org/comm-central/search?string=opentab&find=/calendar/

Seems this is definitely needed.

This should take care

Just another change in Thunderbird that requires Lightning to drop support for 3.0b2 or to implement a solution that works in both 3.0b2 and 3.0b3pre.

(In reply to comment #4) > Just another change in Thunderbird that requires Lightning to drop support for > 3.0b2 or to implement a solution that works in both 3.0b2 and 3.0b3pre. Just to be clear, the API change still allows lightning to work in 3.0b2 as well as 3.0b3pre as long as the consumers of the lightning openTab code are modified simultaneously. (The use of the object merely becomes an odd convention in 3.0b2 rather than required.) This would potentially cause breakage for extensions that utilize the tabmail API to make lightning do things since it is harder for them to make changes in lock-step with lightning.

Yes, I think we are fine, this shouldn't break anything. Pushed to comm-central <http://hg.mozilla.org/comm-central/rev/370680198dec> -> FIXED

Strange mercurial things happened, I needed to repush the nit fixes http://hg.mozilla.org/comm-central/rev/9f2a0925e9cf
