 Version 1.02.73 - 
 ====================================
+  Log failure of pthread_join when cleaning unused threads in dmeventd.
   Fix empty string warning logic in _find_config_str. (1.02.68)
   Fix dm_task_set_name to properly resolve path to dm name (1.02.71).
   Add dm_strncpy() function as a faster strncpy() replacement.
