Privoxy is evolved, and derived from,
the Internet Junkbuster, with many
improvments and enhancements over the original.
Junkbuster was originally written by Anonymous
Coders and Junkbusters
Corporation, and was released as free open-source software under the
GNU GPL. Stefan
Waldherr made many improvements, and started the SourceForge project
Privoxy to rekindle development. There are now several active
developers contributing. The last stable release of
Junkbuster was v2.0.2, which has now
grown whiskers ;-).
