Hello everyone, I recently purchased a UNO R4 minima board and made some adaptations to my previous projects based on the R3 board.
Today when I opened the Arduino IDE, it prompted me that there are available updates for the Uno R4 library. May I ask how can I view the update content of the library? Is there any place where I can check the change log? Clicking "more info" in Board Manager only redirects me to http://www.arduino.cc/. Are these libraries open source? Can I see their change log?
Inspecting the update log of the board library can assist me in determining whether the issue I previously encountered was caused by a preexisting bug in the library.
There is no such thing as "Uno R4 library". Do you mean "Arduino UNO R4 Boards"? If so, that is a boards "platform", not a library. An Arduino library is a completely different thing.
It might seem like I'm being pedantic, but it is very important to use the correct terminology in order to effectively communicate about complex technical subjects as we do here on Arduino Forum.
Assuming you are referring to the "Arduino UNO R4 Boards" platform, yes. You can see the base license here:
Unfortunately the developers of the "Arduino UNO R4 Boards" platform don't provide a conventional changelog, but you can see the complete changeset for a release by checking the Git commit history of the repository. For example, you can see the changeset of the 1.0.2 release here:
