-   V1.1 2/3/202 
+   V1.3 1/21/2023
+      - Included all defined modes in Get/Set Mode (thanks to Mike, KA4CDN)
+      - Fix to allow frequencies greater than 100MHz -(thanks to Bob, KA1GT)
+
+   V1.2 10/22/2021
+      - Fixes bug that caused "WSJTX Rig Control Error"  for versions after 2.2.2
+      - The problem was caused by an unsupported CIV command being sent by WSJTX
+      - This fix responds to unimplemented commands with a NACK instead of an ACK
+      - Bug was reported on the WSJTX groups board.
+
+   V1.1 2/3/2021 
       - various fixes, now works properly with OmniRig and flrig
       - smeter now returns proper BCD code - calibrated to emulate ICOM responses

 If you use find this library does not work with any particular CAT enabled software please let me know via the "Issues" tab on Github.
 
+## Release Notes ##
+Version 1.0.3 1/24/2023 - support for frequencies 100MHz and above.  Support for setting and getting all defined IC746 modes.
+
+Version 1.0.2 - Corrects bug that was causing new version of WSJTX not to connect.  Sends NACK on all unsupported commands,
+
+Version 1.0 - Initial release.

 ## Known limitations ##
 
 Split frequency handling in WSJTX does not work as expected.  The work-around is to configure WSJTX Split for either NONE or "Fake it".  Split functionality has been tested and works as expected using CatBkt.
