What bleachbit does? The Projectsite tells us: BleachBit frees disk space and maintains privacy. Cleans cache, Internet history, temporary files, cookies, and broken shortcuts. Cleans Bash, Firefox, Flash, Google Earth, Internet Explorer, Java, KDE, OpenOffice.org, Opera, RealPlayer, Safari, and more.

Whats happend since the last Version?
- The following changes have been made since 0.7.2:
* Cleans Mozilla Thunderbird versions 2 and 3.

In the original Changelog was a lot more Changes, but these was just for Windows. So have a lot of Fun with the new bleachbit!
