Version 0.8 2.1 MB Works with Thunderbird 2.0 - 2.0.0.*

The following features have been added to Lightning 0.8:

* Lightning 0.8 introduces a task mode that contains the following features
** Quick display of current tasks
** Task preview pane displaying task parameters like the description, from date, due date, category, etc
** Possibility to filter displayed tasks (today's tasks, overdue tasks, completed tasks, etc.)

* New icon set and reworked menu structure that only offers the user those options that are currently available to him in calendar or task mode

* Lightning now contains an event list (also known as "unifinder"), which allows the easy selection and sorting of current, future and past events. The unifinder can be easily enabled or disabled by using the "Find events" button on the Calendar toolbar

* Category colors are now shown next to an event box, giving users a much better overview of their differently categorized events

* Events with alarms now have a visual indicator showing an alarm bell

* A totally overhauled alarm dialog

* Easy conversion of mails, events and tasks into each other. The mode toolbar icons on the left side now function as drop targets, which allows you to convert an e-mail to an event or tasks (or vice versa), just by dragging an e-mail to the calendar icon on the left

* Visual overhaul for the today pane

* Lightning now recognizes the timezone definitions in .ics files created by other applications. This fixes the longstanding issue of Lightning miscalculating the date or time of events contained in those files

* The timezone guessing has been significantly improved

* Lightning now contains experimental support for viewing remote calendars offline. This feature has known bugs and is included for testing purposes only

* Lightning contains several performance fixes, which should improve working with larger calendar files

* You can now define for each of your calendars, whether you want to be notified of alarms for events in these calendars or not

* Special builds with support for Sun Java Calendar Server (lightning-WCAP) are no longer available as the base extension package now contains all the necessary code

* Thunderbird 1.5.0.x builds are no longer supported. Users of Thunderbird 1.5.0.x are strongly encouraged to update to Thunderbird 2. Please use the "Check for Updates..." option in the help menu to get the update

Version 0.7 2.4 MB 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

Version 0.5 2.0 MB Works with Thunderbird 1.5 - 2.0.0.*

Much more polished user interface in the calendar views
Event invitations can be sent and received via iMIP/iTIP (Lightning only)
Working hours are back
Automatic migration of data in Sunbird 0.2, iCal.app, and Evolution
Much improved printing functionality
Better integration of Lightning into Mozilla Thunderbird (Printing, Undo/redo, Copy/paste)
Support for Google Calendar (via the Google Calendar Provider extension)
and much more. A full list of changes that have gone into this release can be found on The Rumbling Edge weblog.

Version 0.3.1 2.2 MB Works with Thunderbird 1.5 - 2.0.0.*

Be sure to install any Daylight Savings Time updates from your OS vendor. Failure to do so will result in erroneous event times.
