Hi! As part of GHC releases users also get a bunch of libraries. These libraries (e.g. array-0.3.0.3 in the last release) aren't uploaded on Hackage. This has some problems, including users on older versions of GHC not being able to upgrade to the new versions and broken documentation on Hackage. I suggest that with each GHC release the new library releases should be uploaded to Hackage. Also, for libraries not maintained by GHC but shipped with the compiler (e.g. containers) the new releases should be done by the maintainers of those libraries to make sure no half-finished code gets shipped (i.e. the repo might not be in a good state to release at all times). P.S. Could someone please remind me why containers ships with GHC? Cheers, Johan
