In our last QA Chat, we decided to revive our old tradition of blogging
about the test day results. So, on our last testday we had really great
participation from a whole host of folks, and four of these intrepid
individuals burned through our Litmus tests[1], running 313 tests.
Overall, 6 new bugs were found. Congratulations to thetux for taking the
cup with a whopping 210 tests run!!

We are continuing to push on toward the 0.8 release candidate. In that
vein, I'd like to make a special plea for testing. We are about to check
in the code that will update the timezone database. Once that happens,
we need you to do two things:

* TEST: We could really use your help in testing this. You know your own
time zone far better than we do, so make sure your calendar switches
into and out of summer time (or doesn't switch at all) at the
appropriate dates for this year.

* BACKUP:If you have been running the 0.8 nightly builds, then you MUST
backup your local (non-network) calendars (export them to ICS) BEFORE
upgrading to a build with this change in it. The details are in
bugzilla[2], but if you are running some of the 0.8pre builds, then this
change might break your calendar when you update to the latest nightly.

**What if I am running 0.7 (or earlier)?**

In that case, you are fine. You should be able to upgrade to 0.8 with no
problems. Of course, it is always a good idea to periodically backup
your calendars anyway. This issue occurs because we don't support
upgrades between nightly versions, only between released versions of the
software.

That said, we know a number of early adopters have already made the
switch to 0.8pre builds and we want them to be aware of this potential
issue.
