Lightning More than three years after version 0.9 arrived, the Mozilla Calendar Project has released version 1.0 of its Lightning calendar extension for the Thunderbird email client. The developers say that the new stable release primarily focuses on "rounding off any sharp edges you may find in Lightning".

Lightning 1.0 has full support for working offline – when the calendar extension's cache setting is enabled – thanks to work done during the recent Google Summer of Code (GSoC). It also includes a "fresh new UI style" for all of the calendar views. Other changes include fixes for a crashing bug that saw the add-on crashing after being launched, and for issues related to alarms, snoozing and recurring events. There are still some known issues, for example, still not being able to create events which repeat on the last working day of each month or every day. Lightning 1.0 requires Thunderbird 8.

Versions for Windows, Mac OS X and Linux are available to download from the Lightning Project's site or can be installed from Mozilla Add-ons. More details about the release, including installation instructions and a full list of bug fixes, can be found in the release notes and in a post on the Calendar Weblog. Lightning is released under Mozilla's disjunctive tri-licence that includes the Mozilla Public Licence, GPLv2 and LGPLv2.1.
