 ## 0.9.7 (TBD, 2018)
 * Bug Fixes
     * Fixed bug when user chooses a zero or negative index when calling ``Cmd.select()``
+    * Restored default behavior of setting cmd_echo to False before running a py script
 * Enhancements
     * **cmdloop** now only attempts to register a custom signal handler for SIGINT if running in the main thread
     * commands run as a result of ``default_to_shell`` being **True** now run via ``do_shell()`` and are saved
