Mozilla.org has released Sunbird 0.5, a new version of its standalone calendar application. The new release has a much more polished user interface in the calendar views. It also re-adds working hours and automatic migration of data in Sunbird 0.2, iCal.app, and Evolution. The printing functionality has been improved, and there is support for Google Calendar (via the Google Calendar Provider extension). Finally, there are reliability, performance, and usability improvements. The software requires Mac OS X 10.2.x or later.
