[question] Where to find unmaintained  recipes?

### What is your question?

Hi,
Recipes change, sometimes dramatically. Where can I find old, unmaintained ones?
For example, I want to see aws-sdk-cpp/1.11.619.
I can conan-download it and look into cache, or I can look into github history.
Is there any other way? Something human-friendly, something of point-and-click type?
Thanks
