Mozilla has released version 0.9 of Sunbird, its calendar application. The Lightning calender extension for the Thunderbird email client has also been updated. There's a huge list of changes under the hood, but here are some of the most noticeable:

• Calendar views have been overhauled
• A progress indicator shows up when you're reloading a remote calendar
• Multi-day events now have visual indicators showing that they're connected
• You can now show the today pane in the tasks mode

Memory use has also been improved and the application is reportedly more stable. Lightning 0.9 is the last version designed for use with Thunderbird 2. Future development will focus on integrating the calendar extension with Thunderbird 3.

Sunbird and Lightning are available for Windows, Mac, and Linux.
