and Thunderbird with the Lightning Extension. In addition to general bug-fixing, Sun focused on calendar views, team/collaboration features and support for the Sun Java System Calendar Server. Version 0.9 was the last planned release for Thunderbird 2. A calendar was originally to be fully integrated into Thunderbird 3, but those plans were changed due to concerns with the product's maturity and level of support. Lightning 1.0b2 is compatible with Thunderbird 3.1, Lightning 1.0b5 is compatible with Thunderbird 5 and 6, and Lightning 1.0b7 is compatible with Thunderbird 7. Lightning 1.0 was released to the public on November 7, 2011. It was released alongside Thunderbird 8.0. Following that, every Thunderbird release has been accompanied by a compatible Lightning point release. Lightning finally started shipping with Thunderbird with version 4.0, on Thunderbird 38.0.1 released in 2015. With the 2020 release of Thunderbird 78, Lightning is now a permanent part of the program.
