BleachBit -- the open source system clean-up utility for Windows and Linux -- has added several new features to its latest version that make it an even better tool for removing unneeded files files from your computer. Support for Google Chrome and Chromium has been greatly improved: BleachBit can now remove everything from DNS prefetch data, to autofill history and DOM storage. Support for HTML5 localStorage cleaning has also been improved and now works with Opera.

On Linux systems, BleachBit can now remove swap files (in addition to swap devices). The Windows version has added the option to remove Windows Update uninstallers -- including hotfixes and Internet Explorer patches. BleachBit's list of supported programs has also grown significantly since we last wrote about the program, and it's well worth checking out the full list of features to see just how much digital crud it can remove from your hard drive.
