That's why we want to keep Daily, Earlybird and Beta running as much as 
possible with latest Gecko - which will help negate the "large" range of 
changes. We know that won't cover everything, but it will go a long way 
to helping.

Accepted, but the point here is that we won't be likely to need to be 
doing an additional x.0.1 release every six weeks due to a completely 
new release on a new gecko, worst-case it'd be once a year.

We have committed to producing two Thunderbird releases a year with the 
support of paid staff. We obviously want to do some betas in support of 
testing, but if the regression is not major but something we'd fix for 
final, we may choose to leave it for a bit longer. Of course, regression 
fixing isn't exclusive to paid staff, and can obviously be done by the 
community as well.

If the community wanted to do extra Thunderbird releases, or SeaMonkey 
wants to do extra releases then the people in the community responsible 
for those pieces will need to pick up the work for those releases, 
including fixing any regressions.
