BleachBit was first publicly released on 24 December 2008 for Linux systems. The 0.2.1 release created some controversy by suggesting Linux needed a registry cleaner.
Version 0.4.0 introduced CleanerML, a standards-based markup language for writing new cleaners. On May 29, 2009, BleachBit version 0.5.0 added support for Windows XP, Windows Vista, and Windows 7. On September 16, 2009, version 0.6.4 introduced command-line interface support.
