Where can I find C++ API Documentation for earlier versions of UE4?

I’m using UE 4.24 (current version) but I’d like to look at earlier versions of the API documentation so I can see how the API changed over time as I follow along with reference projects and earlier tutorials.

For example, I’d like to see the documentation for UGameInstance 4.17 as a function I’m calling seems to have been deprecated and/or removed between 4.17 and 4.24. I can only seem to view the current documentation of 4.24 at UGameInstance | Unreal Engine Documentation .

How can I download or change which version I’m looking at online?
