In addition to the Firefox release today, Mozilla also released version 15.0 of its Thunderbird E-mail client, for Linux, Mac OS X, and Windows. The new release includes some new features:
- Multi-channel chat facility
- “Do Not Track” support for Web searching
- Ubuntu One is now supported for Filelink attachments
- Updated user interface
If you have enabled automatic checking for updates, Thunderbird should inform you of the new version. Otherwise, you can obtain the new version via the built-in update mechanism (Help / About Thunderbird / Check for Updates), or you can download a complete installation package, in a variety of (human) languages.
