  - The asterisk command line -I option and the asterisk.conf internal_timing
    option are removed and always enabled if any timing module is loaded.
 
+Build Options:
+ - Added a new Compiler Flag, REF_DEBUG. When enabled, reference counted
+   objects will emit additional debug information to the refs log file located

+   contrib folder that will process the refs log file.
