NEWS for version 1.2  (released on February 11, 2016)
--------------------------------------------------------------------------

New and Changed Features
========================

o  Improved the efficiency of the conversion procedure for polyhedra
   by adding a quick adjacency check.

o  In the Java language interface, throw an exception when trying
   to build a disequality Constraint.


Bugfixes
========

o  Fixed a bug in the implementation of methods
     Pointset_Powerset<PSET>::relation_with(const Constraint&) const;
   and
     Pointset_Powerset<PSET>::relation_with(const Congruence&) const;
   whereby the computed result for relations strictly_intersects()
   and saturates() could have been wrong.

o  Fixed a bug in the implementation of dense rows.

o  Portability improved.
