The SWI-Prolog 8.0 major release marks mostly a milestone for the internals, stability, deployment options and maintainability of the system. SWI-Prolog extensions and incompatibilities wrt. traditional Prolog are described in extensions.
SWI-Prolog 8.2 notably brings much of the advanced tabling support of XSB to SWI-Prolog: Well Founded Semantics, restraints (bounded rationality), incremental tabling and shared tabling. It also makes rational numbers primary citizens. Using Google's tcmalloc reduces the memory footprint drastically on some multi-threaded workloads.
