This is a minor release with with a few minor changes:
- it is now possible to create the
quotient_froidure_pin
of a congruence with infinitely many classes; - some exception messages were corrected for
Bipartition
objects; - compilation of v2.1.0 to v2.1.3 did not work in cygwin for Windows;
- there was a file missing in the archive, which meant that it wasn't possible to build the documentation.
