> Why there has been no update of HTTRACK since March 2003?> Earlier updates
used to   come one after the other 
swiftly.

There is in fact one release per week, 3.30-XX preversions, 
and "soon" the final 3.30 release should be ready.
The goal is to make a "real stable" release (3.30) after a 
long code freeze.

The latest release (compiled yesterday) can be fount at:
