libsemigroups-2.3.2-bp155.1.7

- Update to release 2.3.2
  * Fix inaccurate exception information for ``replace_subword``
  * string-view: fix bug in append method This bug sometimes
    caused the ``normal_form`` member function of the
    ``Kambites`` class template to return incorrect results, or
    sometimes to cause a crash.

- Update to release 2.3.1
  * Sometimes number_of_congruences erroneously returned 0 for
    the number of congruences with 1 class.
  * If an empty presentation (no generators or relations) was
    used to initialise short_rules, then the Sims1::for_each and
    Sims1::find_if could crash.

- Update to release 2.3.0
  * The "Sims1" class has been redesigned and improved to
    implement a parallel version of the low index congruences
    algorithm.

- Update to release 2.2.3
  * some unspecified minor fixes

- Update to release 2.2.2
  * some unspecified minor fixes

- Update to release 2.2.1
  * This is a minor release fixing a data race (probably) caused
    by setting the global locale

- Update to release 2.2.0
  * New: Sims Low-Index Congruence Algorithm
  * Added permutation group intersections

- Update to release 2.1.5
  * The Schreier-Sims object size function returned wrong results

- Update to release 2.1.4
  * Is is now possible to create the quotient_froidure_pin of a
    congruence with infinitely many classes.
  * Some exception messages were corrected for Bipartition
    objects.

- Update to release 2.1.3
  * Some performance improvements in ActionDigraph::number_of_paths,
    the suffix tree implementation, and in KnuthBendix.

- Update to release 2.1.2
  * New implementations of the linear time algorithm by Kambites
    for equality checking and the algorithm by Mitchell and
    Tsalakou for finding normal forms in small overlap monoids in
    the class `Kambites`.
  * A performance improvement in the implementation of Konieczny
    algorithm, for determining the structure of a finite
    semigroup or monoid.
  * An implementation of the linear time algorithm by Radoszewski
    and Rytter for checking equality of words in free bands in
    the function.
  * A major revision, expansion of the settings, and improvement
    in the performance of the implementation of the Todd-Coxeter
    algorithm in the class `ToddCoxeter`.

- Update to release 2.0.3
  * This release contains a minor change to the FroidurePin class
    template that resolves an issue with the python binding.

- Update to release 2.0.2
  * This release includes some missing operators, adapters, and
    docs were added.

- Update to release 2.0.1
  * konieczny: store lambda/rho positions for D class reps

- Update to release 2.0.0
  * Major rewrite of the functionality in libsemigroups for matrices,
    transformations, and other elements of semigroups. libsemigroups
    has been updated to use C++14 (from C++11), and some
    simplifications were made as a consequence. The documentation has
    been improved, some deprecated functionality was remove, and
    other minor improvements, and simplifications were made.

- Update to release 1.3.7
  * Fix a bug in `Konieczny`
  * Added a limit to `CongruenceByPairs`

- Update to release 1.3.6
  * This is a minor release for compatibility with the GAP
    package Semigroups.

- Update to release 1.3.5
  * Fix unspecified bug in ToddCoxeter

- Update to release 1.3.4
  * There were some bugs in the string formatting in exceptions
    on 32-bit systems.
  * The disjoint sets data structures were refactored completely,
    and their performance improved.

- Update to release 1.3.3
  * Build system changes only
