+
+Some minor issues are fixed in this release:
+
+* [Issue 336](https://github.com/gap-packages/Semigroups/issues/336)
+Rees (0-)matrix semigroups over non-permutation groups sometimes resulted in an
+error. 
+[[J. D. Mitchell](http://www-groups.mcs.st-andrews.ac.uk/~jamesm/)]
+
+* A method was added for `IsEUnitaryInverseSemigroup` for non-inverse
+  semigroups, which previously resulted in no method found. [Chris Russell]
+
+* Some error messages were improved in `ReadGenerators` and `WriteGenerators`.
+
