Updated the README.md with a KC4UPR note. I will now be creating a kc4upr branch.

-#IMPORTANT INFORMATION
+#KC4UPR'S NOTE
 ----------------------------------------------------------------------------
-- Beta 0.26 and Beta 0.261, Beta 0.262, Beta 0.27 is complete test
-- You can download and use it.
+This is a fork of the KD8CEC firmware that will be specific to my uBITX V5
+installation.  My intent is to remove unnecessary code, as well as make some
+GPIO changes based on my use of the Nextion LCD.  Specifically, I'd like to 
+eliminate the use of analog I/O for reading the CW keys, and possibly enable
+control of accessories such as filters using the extra GPIO pins that are
+now available.
 
 #NOTICE
 ----------------------------------------------------------------------------
-I received uBITX a month ago and found that many features are required, and began coding with the idea of implementing minimal functionality as a general hf transceiver rather than an experimental device.
-
-- fixed bugs...
-- Diallock for uBITX's sensitive encoders
-- built in softare Memory keyer and cw options control for CW communication
-- Implementation of CAT communication protocol for Digital Communication (as FT8, JT65, etc)
-- Delay Options for external Linear.
-- and more...
-
-Most of the basic functions of the HF transceiver I thought were implemented.
-The minimum basic specification for uBITX to operate as a radio, I think it is finished.
-So I will release the 0.27 version and if I do not see the bug anymore, I will try to change the version name to 1.0.
-Now uBITX is an HF radio and will be able to join you in your happy hams life.
-Based on this source, you can use it by adding functions.
-
-I am going to do a new project based on this source, linking with WSPR, WSJT-X and so on.
-Of course, this repository is still running. If you have any bugs or ideas, please feel free to email me.
+- Now Release Version 1.20 on my blog (http://www.hamskey.com)
+- You can download and compiled hex file and uBITX Manager application on release section (https://github.com/phdlee/ubitx/releases)
+- For more information, see my blog (http://www.hamskey.com)

 Prepared or finished tasks for the next version
-  - Most of them are implemented and included in version 0.27.
-  - User Interface on LCD -> Option by user (not need)
-  - Include WSPR Beacone function - (implement other new repository)
-    complete experiment
-    need solve : Big code size (over 100%, then remove some functions for experment)
-                 need replace Si5351 Library (increase risk and need more beta tester)
-                 W3PM sent me his wonderful source - using BITX, GPS
