A beta version of CLIPS 6.30 for Windows is available for download. It incorporates the following changes:
Performance Improvements - Rule performance has been improved particularly in situations with large numbers of fact/instances or partial matches.
64-bit Integers - Integers in CLIPS are now represented using the "long long" C data type which provides a minimum of 64 bits of precision.
Pattern Addition - The initial-fact and initial-object patterns are no longer used in triggering rules. When printing partial matches, the * symbol is used to indicate a not or exists pattern that is satisfied.
