Is there a reason why you don't update it automatically and regularly, with the original source as the upstream branch, with master as the one you modify for your own purposes?
For me, programming is a hobby. I am a beginner programmer. I did not set myself the task of constantly updating the library in git. I did not know that it is possible to configure its automatic update. I can update the library to the latest version, and this will not affect the revision that we use in the main project.
If you tell me how to set up automatic updates, I will be happy to enable it.
