How do I find out what has changed in a specific version of Matlab/Simulink?

I have found the documentations for various versions of Matlab. Is there a way to easily check if changes have taken place in specific parts of the software? For example, consider the two documents for s-functions:

https://uk.mathworks.com/help/pdf_doc/simulink/sfunctions.pdf

https://uk.mathworks.com/help/releases/R2017a/pdf_doc/simulink/sfunctions.pdf

Both provide detailed explanations for s-functions. The first link is for R2018b and the second one for R2017a. Is there a way to know if anything has changed between these two releases without manually going through the giant documents and comparing? I am asking because I find one of them a bit more informative and better explained than the other.

See the documentation section on Release Notes (link). For specific Simulink release notes, see Simulink Release Notes (link).

The information available for MATLAB and all the Toolboxes goes back several releases. You can also specifically search it.
