The currently served ClamWinPortable support page seems to have an outdated version history. The download page lists the current version as 0.94.1 Rev. 2, but the version history on the ClamWinPortable support page indicates the last revision was version 0.90.2, not 0.94.1 Rev. 2. Any chance the page could be updated?
I don't know what has changed since version 0.93 [what I am currently running].
