Feature selection functions in R2018b

I am using MATLAB R2018b Update 2 and would like to use some of feature selection functions such as fscchi2 (https://de.mathworks.com/help/stats/fscchi2.html) and fscmrmr (https://de.mathworks.com/help/stats/fscmrmr.html), which come with Statistics and Machine Learning Toolbox. I have this toolbox installed (Version 11.4). However, I still cannot use those 2 functions above. Are they come on the later release of MATLAB?

Where can I see list of supported functions in each MATLAB release?

At the end of the documentation page for the fscchi2 function it states the function was introduced in release R2020a.

Similarly the documentation page for the fscmrmr function states it was introduced in release R2019b.

If you open the documentation for a particular release (the "Other Releases" link on the Documentation Home) you can click on the Functions link in the blue bar immediately below the top-level sections (Products, Solutions, Academia, etc.) to get a list of functions. Then click on a particular product for the list of functions in that product in that release. For example, here is the list of functions in Statistics and Machine Learning Toolbox in release R2019b. You will see it contains fscmrmr but not fscchi2.
