MATLAB: How to find when a feature was introduced in MathWorks products?

Once I wanted to find when = in which MATLAB Release the Fast Restart feature of Simulink was introduced.
This post explains the way to find it out.
1.) Go to the MathWorks product documentation http://www.mathworks.com/help/
2.) Search for "fast restart" (with quotation marks around)
3.) On the left under "Refine by Product" select Simulink
4.) On the left under "Refine by Type" select Release Notes

Direct link looks like this: http://www.mathworks.com/help/search.html?qdoc=%22fast+restart%22+type%3Arn+product%3Asimulink

5.) Click on the one remaining search entry and you should find what you are looking for.
