"latest" links to API docs on HackageDB?

HackageDB documentation links for the "latest" version of packages appears to be missing. For instance, the haskell.org wiki at http://www.haskell.org/haskellwiki/Opengl points to Haddock'ed API documentation at http://hackage.haskell.org/packages/archive/OpenGL/latest/doc/html/ http://hackage.haskell.org/packages/archive/GLUT/latest/doc/html/ but there is nothing there (404 not found). Searching around, I eventually discovered documentation for specific versions (2.1 and 2.2.1.1), but having a simple "latest" link that always works would be very useful. Regards, Malcolm
