Mozilla corporation is currently distributing an update to the popular desktop email client Mozilla Thunderbird. The new version of the email program has not been officially announced yet, this will be done once the distribution to mirror servers worldwide has been completed.
This also means that there is no official release log yet, only the beta release notes are available and they list several fixes to improve stability and security of the email client, as well as several fixes to the program’s user interface.
The security fixes alone should be reason enough for Thunderbird users to update the email client as soon as the new version gets released by the development team.
A quick look at Bugzilla lists a total of 84 different bugs that have been fixed in Thunderbird 3.1.7 including a total of 26 different critical issues and one blocker issue. Most issues listed are related to crashes in the email client.
As part of Mozilla Thunder bird ongoing security and stability update process, we strongly recommend that all Thunderbird users upgrade to these releases. If you already have Thunderbird 3.1 or 3.0, you will receive an automated update notification within 24 to 48 hours. You can also manually fetch this update by selecting "Check for Updates..." from the Help menu.
Thunderbird users who do not want to wait until the new release has been officially announced can download the new version from the Mozilla server, one of the worldwide mirror servers, or sites like Softpedia which usually carry only the English language version.
