Release Date: July 24th, 2010

Installing
We provide Lightning for Windows, Linux and Mac OS X in a variety of languages. Windows users must have Windows XP or later. Mac OS X users need to use MAC OS X 10.4 or later.

IMPORTANT: Install the updated timezones for Windows XP or later. Information on obtaining the updated timezones can be found in Microsoft Knowledge Base article 955839. Not updating your Windows timezones will result in unreliable and erroneous display and entry of time data! Be sure to do this!

Lightning runs as an extension for Mozilla Thunderbird 3.1.x. Thunderbird 2.0.0.x or 3.0.x is no longer supported. Please use the earlier 1.0b1 (Thunderbird 3.0.x) or 0.9 (Thunderbird 2.0.0.x) release if you still use an earlier version of Thunderbird.

If you are using Seamonkey, please also use the older Lightning 1.0b1. This release doesn't support Seamonkey, but the next release will likely do so again.

Known Issues
This list covers the major known issues with Lightning 1.0 beta2. Please read this list before reporting any new bugs.

All Systems
  • Lightning 1.0 beta2 will attempt to guess your timezone on startup. As this
    is only a best guess, you must manually set the timezone
    in the Thunderbird Preferences/Options dialog before entering data. Not
    doing so may cause events to appear at the wrong time


  • The experimental support for viewing remote calendars
    offline has various known issues in the area of performance and calendar
    data display. It does not support the offline editing of events and tasks

  • It is impossible to load several calendars with different passwords on
    the same server.
    (bug 247486)

  • "By weekday" and "by day" recurrence types (such as "recur on the last
    weekday of the month") are not supported.

    the task list and the unifinder.
    (bug 373251)

    mode, will only be shown by Outlook 2000 if the Service Pack 3 (SP3) has been

    (bug 377761)


  • Popup alarms/reminders don't work with WCAP server
    (bug 380423)

    (bug 448453)

  • Events with an UID that contains '/' are not displayed
    (bug 465853)

  • Due to an internal database upgrade, the first startup after upgrading

Version 0.9 2.2 MB Works with Thunderbird 2.0 - 2.0.0.*

The following features have been added to Lightning 0.9:

* Events spanning days now have a visual indicator indicating them as connected events

* When reloading a remote calendar a progress indicator is now shown

* The so-called "minimonth" (small calendar month in the upper left) has been given a visual overhaul

* The calendar views (day, week, multiweek, month) have been given a visual overhaul

* The today pane can now be displayed in calendar mode and task mode as well

* CalDAV support and interoperability with various CalDAV servers has been improved

* iMip/iTip support (support for email invitations) has been greatly improved

* The application stability and memory consumption has been greatly improved

* Lightning 0.9 is intended to be the last release for the Thunderbird 2 series. For the future we are planning to integrate Lightning fully into the upcoming Thunderbird 3 release

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
