+  o Bugfixes:
+    - Fix compilation warning with some versions of clang that would prefer
+      the -Wswitch-enum compiler flag to warn about switch statements with
+      missing enum values, even if those switch statements have a default:
+      statement. Fixes bug 8598; bugfix on 0.2.4.10-alpha.
