+## PCB Changelog
+
+### V1.1 (First release)
+
+#### Changes
+
+* Switched LM25765 Bucks to TPS5430DDAR
+* Removed all electrolytic capacitors, replaced with tantalum ones
+* Added smoothing outputs to INA180 current outputs (For better reading with ESP32's ADC)
+* Added ESD protections
+* Replaced the Type-C port with one that would not so easily break off the board
+* Allow for either CP2102N or CP2104N UART bridge to be used
+* Better noise filtering for ATF temp, N2 and N3 pulse counters
+
+#### New features
+
+* Added support for the legacy TRRS shifters found in W210 and older cars!
+* Added CANBUS isolation choke
+* Added additional credits to PCB silkscreen
+
+### V1.0 (Only available to beta testers)
+
+NOTE: This is a closed beta board, so only the schematic was made public
+
+* Initial release board for beta testers only

 # Ultimate NAG52
 An open implementation of NAG52 (722.6 Transmission controller), complete with KWP2000 diagnostics and CANBUS support
 
-## About GPL and lack of Gerber
-
-This project follows the GPL license, however right now you will notice there is only the schematics of the PCB avaliable. So what about the PCB Gerber file?
-
-Currently, the Gerber file is private whilst the board undergoes testing. This is to prevent anyone from making a PCB which has potential issues. The board is being tested by a beta tester group. Once testing has concluded and the product is ready to be sold (Assembled PCBs), the Gerber will then become avaliable in this repository!
+## PCB Schematics
+Check the [PCB](PCB/) folder for schematics, and **NOW GERBER FILES!**
