Story Topic:


Installed this update and it notified me that Lightning need updating.
Thunderbird and Lightning installd OK, but lost my existing calendar!!!

Recommend users backup their calendar file before installing this update.

Ignore above, calendar has mysteriously reappeared intact?? WTF?

First TB updates to 3.1, at which point your calendar is disabled (since 1.0B1 is incompatible with 3.1). Then your calendar is updated to 1.0B2 and will appear in TB after you restart it. You can't upgrade calendar first because 1.0B1 won't work on 3.0.x. That make sense?

Sometimes, the impossible can become possible, if you're awesome!
