That said, we don't advertise changes by other boot packages unless they're really important, like backwards incompatible changes. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14857#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I just saw that `base` library in mentioned in GHC changelog and thought that every change in bundled libraries is documented there. I think that mentioning only most important changes and providing link to library changelog is the best solution! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14857#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
