What's New in Mozilla Sunbird® 0.7

Mozilla Sunbird 0.7 is the latest release of our standalone calendar application. We recommend that all users upgrade to this latest version.

  • A redesigned event/task dialog has been enabled to gather feedback from the community. It offers a much cleaner user interface and additional functionality including:
    • Events/Tasks can be created in different timezones
    • Integrated display of recurrence patterns, reminders
    • Custom recurrences and reminders
    • Clear separation between tasks and events
  • The new event summary dialog lists all the details of tasks and events for calendar which are read-only.
  • Colliding events (events in the same time slot) are shrunk so that they fit into the display of a day. This no longer affects other events on the same day.
  • Localized releases of Sunbird in Chinese (simplified), Georgian, Lithuanian, Portuguese (European), Spanish (Argentina) and Turkish
  • A full list of changes that have gone into this release can be found on The Rumbling Edge website.

Restart Sunbird in Safe Mode. On Windows, start using the "Safe Mode" shortcut created in your Start menu or by running sunbird.exe -safe-mode. On Linux, start with ./sunbird -safe-mode and on Mac OS X, run the following command in Terminal: /Applications/ -safe-mode When Sunbird is started in Safe Mode, all Add-ons are disabled.
