Where can I find archived (<=4.25) documentation?

The official documentation only shows 4.26, 4.27 & 5… Are all previous documentation simply lost to time??

Thanks for any help at all!

To clarify, I’m not talking about the local BlueprintAPI-HTML & CppAPI-HTML archives in my folder. I’m referring to the equivalent of this page: https://docs.unrealengine.com/4.26/en-US/
