Lightning 1.0 Beta 4 RC 2 (released today) works with Thunderbird 5.0 and can be obtained via AMO. While the AMO page does show Lightning 1.0 Beta 4 in the description it is still downloads 1.0 Beta 2. Warning: Attempting to force older versions of Lightning to work with Thunderbird 5.0 will not work.
For those looking for the Provider for Google Calendar there is a new version available as well.
Hmm, but no updated gdata provider. Is it safe to assume it hasn’t been changed since 1.0b4rc1?
Interesting…I updated to 0.8 today which works with Thunderbird 5.0 after I had downloaded 0.8pre from the Mozilla FTP site. Where did you find 1.0b4rc1?
The updated 0.8.0 version is on AMO now.
Oops, sorry–I meant 0.8pre. I got gdata provider from the Mozilla FTP site, where it was in the same directory with lightning 1.0b4rc1.
Happily running 0.8 now after getting TB 5.0.
