Sunbird Comments

Discontinued

Comment by Anamon
about Sunbird and Lightning, Thunderbird Aug 2012

Sadly, Sunbird has been discontinued in favour of the Thunderbird-integrated Lightning plug-in, for a lack of developers. 1.0 Beta 1 was the last release. People who prefer a stand-alone calendar application will have to look elsewhere.
