Following yesterday’s Firefox update, Thunderbird has followed the same path and a fresh update is now available. Thunderbird 2.0.0.5 includes fixes for a couple of critical security bugs and a new localization, Korean, is also now available.

For the security updates alone, Thunderbird users are strongly encouraged to update. You can either wait to be prompted for the update within 2 days or for faster results, in Thunderbird’s Help menu, select Check for Updates… and follow the on screen intructions.

Thunderbird 2.0.0.5 release notes.
