In North America, some daylight savings time changes are taking effect
in March that the 0.3 code does yet account for.  It seems likely that
many people are already scheduling events in March (since it's only six
weeks in the future, and the changes themselves will be taking effect in
seven weeks).  So it seems like the best way to serve our users is by
pushing out a maintenance release as quickly as possible.

Our original plan for dealing with this was to have 0.5 released by now.
  However, there is still a bunch of work left to do for 0.5, and even
if we were to cut most of that work, there'd still be bunch of QA and
stabilization to do.  So after a bunch of IRC discussion yesterday,
we've instead determined to do a very minimal 0.3.1 release as quickly
as we reasonably can.  I've started a wiki page to track this work at
<http://wiki.mozilla.org/Calendar:0.3.1_Release_Status>.

This will have a small amount of effect on 0.5 work, in the sense that
0.3.1 work will be given priority.  In particular, I'm putting the
timezone backend rework on hold in order to focus on 0.3.1.
Additionally, mvl (rather than I) will be posting in more detail about
the new event dialog plans we discussed in the Wednesday meeting shortly.
