Fri Oct 28 11:43:26 UTC 2022 - Jan Engelhardt <jengelh@inai.de>
- 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.
-------------------------------------------------------------------
Tue Oct 11 06:47:03 UTC 2022 - Jan Engelhardt <jengelh@inai.de>
- 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.
-------------------------------------------------------------------
Thu Sep 29 10:51:56 UTC 2022 - Jan Engelhardt <jengelh@inai.de>
- 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.

Sat Aug 13 08:30:28 UTC 2022 - Jan Engelhardt <jengelh@inai.de>

by setting the global locale

-------------------------------------------------------------------
Fri Mar 4 18:53:58 UTC 2022 - Jan Engelhardt <jengelh@inai.de>
- 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.
-------------------------------------------------------------------
Thu Dec 16 19:38:20 UTC 2021 - Jan Engelhardt <jengelh@inai.de>
- Update to release 2.1.3
* Some performance improvements in ActionDigraph::number_of_paths,
the suffix tree implementation, and in KnuthBendix.
-------------------------------------------------------------------
Tue Nov 30 11:46:47 UTC 2021 - Jan Engelhardt <jengelh@inai.de>
- 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`.
-------------------------------------------------------------------
Thu Nov 11 11:33:32 UTC 2021 - Jan Engelhardt <jengelh@inai.de>
- 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.
-------------------------------------------------------------------
Mon Sep 20 20:41:07 UTC 2021 - Jan Engelhardt <jengelh@inai.de>
- Update to release 2.0.2

-------------------------------------------------------------------
Sat Aug 28 19:50:37 UTC 2021 - Jan Engelhardt <jengelh@inai.de>

- 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.
-------------------------------------------------------------------

* Added a limit to `CongruenceByPairs`
-------------------------------------------------------------------
Fri Feb 5 17:53:39 UTC 2021 - Jan Engelhardt <jengelh@inai.de>
- Update to release 1.3.6
* This is a minor release for compatibility with the GAP
package Semigroups.
-------------------------------------------------------------------

-------------------------------------------------------------------
Fri Nov 27 17:16:44 UTC 2020 - Jan Engelhardt <jengelh@inai.de>
- Update to release 1.3.4
* There were some bugs in the string formatting in exceptions
