 ### Minor changes
 * Added specific clixon_suberrno code: XMLPARSE_ERRNO to identify XML parse errors.
+* Removed all dependency on strverscmp
+* Added libgen.h for baseline()
 	
 ### Corrected Bugs
+* There was a problem with ordered-by-user for XML children that appeared in some circumstances and difficult to trigger. Entries entered by the user did not appear in the order they were entered. This should now be fixed.
