+  1.0.0.6 20220624  added   - Busy flag on optional GPIO pin
+                    added   - command for MP3Folder, folder/track format
+                    added   - an event so that busy flag can be used in Berry
+                    ToDo    - test changes with SV17F
+                    ToDo    - change MP3Folder format to use two arguments MP3Folder 3,9
+                            - Tom@lafleur.us
+
   1.0.0.5 20210121  added   - support for DY_SV17F Player (#define USE_DY_SV17F)
                             - cmds supported:
