On this web page:

https://github.com/sparkfun/SparkFun_RTK_Everywhere_Firmware/releases/tag/v3.0

…there is a link at the bottom labeled “[Source code(zip)]"

that links to:
https://github.com/sparkfun/SparkFun_RTK_Everywhere_Firmware/archive/refs/tags/v3.0.zip

However, when I followed that link and downloaded the zip file, I found that the RTK_Everywhere source files (the contents of the RTL_Everywhere folder) are identical to those files in the RTL_Everywhere V2.3 release.

Is this expected?
