Calendar:Lightning:0.1:Release Notes

This is a draft. The current nightly builds have a set of known issues as well any problems shown in the 0.1 blocker list.

What is Lightning 0.1?

Lightning 0.1 is an embedding of the Mozilla calendar code specifically designed to run inside Mozilla Thunderbird 1.5. This release is a preliminary, non-production release designed to showcase the work that's been done and allow contributors to help us test it out.

What can Lightning 0.1 do?

• Help you keep track of your personal schedule
• Subscribe to calendars on the Internet (via HTTP/WebDAV)

Important things to know before trying Lightning 0.1

• Modifying ICS calendars or entries created by programs other than Lightning may result in data-loss.
• Editing calendars by more than one user may result in data-loss
• There is no mechanism for undoing calendar operations.
• Item recurrence and alarms have not been heavily tested.
• This is a preliminary release, and despite our best efforts, may have other bugs that can eat your data. Always make regular backups! - See {YourProfileDirectory}/backup/ and this page section "WebDAV Calendar Backup System" for details of the backup scheme.

Missing/Incomplete Features

There are a number of parts of Lightning that are not yet complete or still have issues. Important such features include:

• No functional integration between email/addressbook and calendar functionality exists yet.
• Printing support is minimal.
• CalDAV support is extremely basic, has issues, and is difficult to set up
• Offline support only works for local calendars.
• Syncing with other calendar software (such as handheld PIM devices) is not supported.
