After 4 years, there’s a new version of PySwip. I’ve released v0.3.0.

PySwip is an open source library that enables running Prolog queries in Python via a foreign language interface to SWI-Prolog. It has no dependencies, and it works wherever SWI-Prolog runs, Linux, Windows, MacOS, OpenBSD, and elsewhere.

Here are some of the highlights from the change log:

• SWI-Prolog 9.x is supported.
