Four weeks ago we released Lightning 1.0 beta1. At the time we also said, that we would make a 1.0 beta1 release available for Sunbird as well, the last Sunbird release from us as previously announced.
Now what’s holding it up? The answers are: technical stuff and real life. To elaborate more, we’re still having problems to produce the Sunbird 1.0 beta1 release builds in all our supported locales. The only two people who could fix that (Philipp and Gozer) are either too busy because they have to learn for their university exams (Philipp) or too busy, because they have to work on getting other (higher priority) releases out of the door (Lanika 3.1 alpha1 and Thunderbird 3.0.2).
The good news is that Philipp’s exams will be done in the coming week and Gozer’s main time consumer is either already done (Lanikai 3.1 alpha1) or will be done from his side in the coming week (Thunderbird 3.0.2). So expect a Sunbird release shortly thereafter.
