+- Update to version 1.3.5
+  * Rename `build-normaliz.sh` to `prerequisites.sh` to match an
+    undocumented convention used across several packages.
+  * Minor build system tweaks
+- Update to version 1.3.4
+  * Fix regression that broke building NormalizInterface on macOS
+- Update to version 1.3.3
+  * Update to Normaliz 3.9.3
+  * Improve build system to honor CPPFLAGS environment variable
+  * Explicitly set a so-called "run path" / "rpath" when linking
+    against the bundled copy of Normaliz (improves compatibility
+    with future versions of the GAP compiler `gac`, which will
+    not be using GNU libtool anymore)
+- Update to version 1.3.2
+  * Fix building on Cygwin
+- Update to version 1.3.1
+  * Fix building on FreeBSD
+- Update to version 1.3.0
+  * Update to Normaliz 3.9.1
+  * Improve the new build system
+  * Various janitorial changes
+- Update to version 1.2.0
+  * Update to Normaliz 3.8.4
+  * New build system
+  * Various janitorial changes
+- Update to version 1.1.0
+  * Add support for rational inputs, e.g. polytopes with rational
+    coordinates
+  * Update build system for improve compatibility with GAP >= 4.9
+  * Completely rewrote build-normaliz.sh (now downloads a tarball
+    using curl or wget, instead of cloning a git repository)
+  * Fix a potential crash when freeing proxy cone objects
+  * Fix 'unknown cone property' that could occur when using newer
+    versions of Normaliz, e.g. version 3.5.4
+  * Display the Normaliz version as part of banner string
+  * Loads of internal and janitorial changes
+  * Require Normaliz 3.5.4 or newer (and add support for its
+    new features)
+  * Sebastian Gutsche is no longer package maintainer
