- Update to release 3.1.3
* Add a `to_human_readable_repr` function for the `Action` class.

classes.

Sat Mar 22 09:07:35 UTC 2025 - Jan Engelhardt <jengelh@inai.de>
- Update to release 3.0.0
* Reporting during a computation has been improved
* Class interfaces were reduced in size, with member functions
only calling other public member functions being moved into a
helper namespace.
* Most classes now use iterators exclusively in their interfaces.
* The class ``ActionDigraph`` has been renamed ``WordGraph`` for
consistency with the mathematical literature.
* Some functionality that used to be in ``ActionDigraph`` has
been move into the classes ``Gabow`` and ``Paths``.
* The class ``Dot`` facilitates the creation and rendering of
graph descriptions in the DOT language of the Graphviz graph
drawing software.
* Conversion from one libsemigroups type to another is now
exclusively via the function template to.
* Many constructors for classes where it is expected that many
instances will be created (such as Transf, for example) do not
perform any checks on their arguments. Alternative versions of
these constructors, that do perform checks, are available using
the ``make`` function.
* Range objects are used fairly extensively throughout the
library.
* libsemigroups has been updated to use C++17 (from C++14).
