Version 4.0 of PDQ (Pretty Damn Quick) is in the pipeline---it's been there for quite some time, actually (blush). The current hold up is related to getting both the Perl and the new Java version through the QA suite designed by Peter Harding. As soon as that is sorted out, we'll release it; probably in two pieces, keeping the Java PDQ separate initially. Also included will be updates to PyDQ (python) and a new PHP version.
