How do you find out which version(s) of a particular library includes a given definition? In my case, I noticed that gloss fails to install with the GLFW backend...
Graphics\Gloss\Internals\Interface\Backend\GLFW.hs:12:45: error:
Module `Graphics.UI.GLFW' does not export `WindowValue(..)'
cabal: Leaving directory 'C:\Users\Jonatan\AppData\Local\Temp\cabal-tmp-
22520\gloss-1.11.1.1'
... so I'd like to find out when WindowValue was removed. I've tried Hoogle, Stackage and Hayoo, with no luck.
