We are very pleased to announce the availability of Sat4j 2.3.2.
The main new feature for the users is the ability to visualize the search and control the solver thanks to the new "remote control" (see http://www.satcompetition.org/PoS12/slides-sat4j.pdf for details).

We also provide different CNF encodings for cardinality constraints, in addition to the native support of such constraints in our solvers.

Note that unlike previous 2.x releases, the jars are now Java 1.5 compatible, we dropped support for Java 1.4.

There will be a last maintenance release 2.3.3 before the end of the year.

Have fun!
