 Version 4.0
 -----------
 
+* rTBD - Remove std::string::append template methods which should be inline
+
+  These functions should never have had visible definitions in the dylib but
+  since they were previously not specified with 'inline' they accidentally
+  got emitted. This change is non-ABI breaking because every "linkage unit"
+  must contain its own definition.
