The message that started this thread 
<> is 
that info for 2.0.0.x, and the development plan linked to from that 
message <> 
is that info for more recent versions.

To be more specific, our current hope is not to support Thunderbird 
3.0.x for too long after we ship Thunderbird 3.1, but rather to upgrade 
all of our 3.0.x users to 3.1.x fairly quickly, in large part because 
the set of changes between 3.0 and 3.1 is relatively small.

That does, however, depend on a some externalities, such as 3.1.x user 
feedback as well as how quickly add-on authors make their 3.0.x addons 
compatible with 3.1.
