Version 0.7 2.2 MiB Works with Thunderbird 1.5 - 2.0.0.*

Lightning 0.7 is the latest release of our calendar extension for Mozilla Thunderbird. We recommend that all users upgrade to this latest version.

It is now much easier to switch between the mail and calendar parts of Thunderbird thanks to a user interface redesign

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
Attendees can be added from a local or corporate LDAP directory

Free-Busy information is available for users of the Sun Java Calendar Server

Integrated display of recurrence patterns, reminders and attendees

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

The Today Pane gives a quick overview over your current tasks and upcoming events. The Today Pane can be enabled/disabled by a toolbar button

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 Lightning and Sunbird in Chinese (simplified), Georgian, Lithuanian, Portuguese (European), Spanish (Argentina) and Turkish
