Thunderbird will move to two-week releases in September

Thunderbird will double its release pace in September, switching from monthly updates to a new version every two weeks. Thunderbird 154 is the first interim release after version 153 became the Extended Support Release (ESR), giving administrators and cautious users a slower, year-long support option.
