Comment 2 for bug 923372

i upgraded to the newest version of Thunderbird (10.0.2+build1-0ubuntu0.11.10.1), but at this moment at least, the calender extension xul-ext-lightning has not also been updated, and the older version in the repos is incompatible with the newest version of Thunderbird. This means I can't use my calander now until the newest version is made available in the repos. shouldn't these all be released at the *same time* so that users like me don't get stuck not being able to use their calander for some indeterminate amount of time?
