+# v0.1.4
+
+- Removed Versionize proc macro support for unions. Serializing unions can lead to undefined behaviour especially when no
+layout guarantees are provided. The Versionize trait can still be implemented but only for repr(C) unions and extensive care
+and testing is required from the implementer.
+
 # v0.1.3
 
 - Added extra validations in VersionMap::get_type_version().
