Mozilla has officially released Thunderbird 24.0, an email and RSS client, for all the available platforms, including Linux.
Users have been wondering when the Thunderbird version will catch up with the Firefox one. For a while now, Mozilla has only released increments for the 17.x branch, but the time for the 24.0 version has finally arrived.
There aren't any official details yet, but so far, all three Beta releases for the 24.x branch have been about bug fixing and performance improvements. You shouldn't really expect any new features or major changes.
