+### Version 5.3.4 (released 24/01/2024)
+
+This is a minor release that fixes some issue in the build system, applies some
+new linting rules, and perhaps most importantly re-enables the use of [HPCombi][]
+in [libsemigroups][]. A number of different things were wrong which meant that:
+
+* the correct configuration flags weren't set for building [Semigroups][] when
+  [HPCombi][] is enabled;
+* [HPCombi][] was not detected properly because of a mistake in the path;
+* the kernel module couldn't be built even when the last two items were
+  resolved, due to some missing functionality for [HPCombi][] types.
+
+These issues arose because the main author no longer has access to any machines
+running x86, and so the support for [HPCombi][] slowly eroded, unnoticed by me,
+over time.
+
+The other changes in this release are:
+
+* some changes of PreImages... to NC versions (for compatibility with
+  forthcoming changes to GAP) by @cdwensley in
+  https://github.com/semigroups/Semigroups/pull/965
+* buildsys: unify rpath handling by @fingolfin in
+  https://github.com/semigroups/Semigroups/pull/976
+* Support GAP on Cygwin with libtool removed (for compatibility with
+  forthcoming changes to GAP) by @ChrisJefferson in
+  https://github.com/semigroups/Semigroups/pull/979
+* Fix for [HPCombi][] by @james-d-mitchell (fixes the issues itemised above) in
+  https://github.com/semigroups/Semigroups/pull/978
+* Linting by @james-d-mitchell in https://github.com/semigroups/Semigroups/pull/980
