PDQ 7.0 Dev is Underway

May 14, 2016 | Neil Gunther

The primary goal for this release is to make PDQ acceptable for uploading to CRAN. This is a non-trivial exercise because there is some legacy C code in the PDQ library that needs to be reorganized while, at the same time, keeping it consistent for programmatically porting to other languages ...
