Released 12-Nov-2004.
Can I suggest that you tidy up the Files page on SourceForge?
I just came to install vpopmail on a new system and thought 5.4.2 was the latest version as it appears at the top in the Devel section (Stable version will be older than Devel, right?).
Vistors to that page have to scroll down quite a way to find the latest Stable version (on my system, page down twice before Stable appears at the bottom of the screen - once more to get it at the top.)
Cheers,
