QUACPAC 1.3.0

This release represents the first major reworking of the QUACPAC toolkits and applications in several years. Any users of prior versions of QUACPAC will quickly notice several significant changes. First, this version of QUACPAC does not contain a new release of protein_pka program. We are in the midst of a major rewrite of the protein_pka program. We hope that this work will bring major improvements in the usability, science and analysis of the protein_pka program, yet we do not want to delay the release of the entire QUACPAC package waiting for the protein_pka program. The current QUACPAC release does not contain protein_pka, but it will be included in a future release when the rewrite is complete. In the interim, we hope you find the bug fixes and new features included in this release useful.

The preps and qpd programs will no longer be supported future versions of QUACPAC.
