There are a few bugfixes as well plus improvements to the free disk space wiping routines.

CCleaner 2.17.853 is now available.

The most interesting addition in this version is the ability to wipe free disk space.

There was already a secure deletion routine implemented in CCleaner, but until now, it was able to only wipe files. This meant that if you deleted a file the usual way and then remembered you wanted to wipe it, you were out of luck.

However, CCleaner 2.17.853 can wipe all free disk space on a partition (or more, there’s a new entry in Options->Settings). The way it does this is interesting and strange at the same time: it seems to create a huge file, taking up all your free disk space, and then it wipes it using the usual secure delete routing.

Some users reported problems with this new functionality, but I’m sure the developers will iron out any existing quirks for the next release.
