This version has a new filter concept which allows
better filtering. The first advantage is
decompression of Zip and UPX compressed files and
detection of uninfectable files (like graphics and
audio files) for faster scanning. It probably
breaks the detection of some viruses, but work is
being done to remedy this.
This release replaces the plain 'virussignatures.txt' with Credo files. These are digitally signed archives, signed with digitally signed keys from the OAV project. Everyone can get such a key and publish virus patterns by now.
Support for a digitally signed virus signature file (you have to use the new virussignatures file with it). From now on, only virus patterns generated by PatternFinder will be accepted if you send the virus with it, so that the pattern can be verified.
This release has POST and FILTER support for Squid virus scanning. You can transparently scan all Squid traffic for virii. Connections are allowed from localhost only. There is multithread support.
