Version 3.1 is currently being tested
Version 3.1 is the first new Visual MINTEQ version for two years. It contains a large number of improvements. Perhaps the most significant new feature is the rewritten interface for the Biotic Ligand Model. Users are welcome to download a fully functional beta of version 3.1 (however, the documentation is still not updated) The regular version 3.1 is expected to be released some time during January 2014.
