The “Lightning” (Calendar) project in Pontoon is now part of the Thunderbird project. This change is part of a larger project to separate Thunderbird localization from Firefox. I’d like to thank Flod and Mathjazz for their help and keeping me motivated throughout.
I would like to thank the localization community for their continued work on Thunderbird. Feel free to contact me through Pontoon, email, or Matrix with any questions that you have.
