Lightning brings the Sunbird calendar to the popular email client, Mozilla Thunderbird. Since it's an extension, Lightning is tightly integrated with Thunderbird, allowing it to easily perform email-related calendaring tasks.
Lightning is a fairly new development. Its first public release was in early 2006. However, being based off of the same backend code as Mozilla Sunbird®, it is maturing quickly.
For the details of what's new in this release, please read the Lightning Release Notes.
Some goals for future releases are:
Even tighter Thunderbird integration
email-to-task linkage
Thunderbird address book integration
more robust iMIP support (meeting invitations)
more robust CalDAV support
offline calendar use
printing
device synchronization (Palm, PocketPC, iPod, phone, etc.)
