Typescript typings for gojs 1.7.2

I am currently using gojs1.7.2 and no plans to upgrade to latest version. Want to know location to download go.d.ts and go-debug.d.ts for this particular version

http://gojs.net/latest/release/go.js

http://gojs.net/latest/release/go-debug.js

http://gojs.net/latest/release/go.d.ts

You can do this for any version. You can also use the GitHub history.
