The long anticipated Haskell Platform 2014.2 release, including GHC 7.8.3,
and numerous updated packages, is almost here!

We have created "Release Candidate 2" installers for OS X and Windows, and
believe, barring show stopper issues, creepers exploding, or unexpected
trips to the nether, these will likely be blessed as the final by the end
of the week.

If you would like to be an early adopter, please try 'em out...

   - source tarball: haskell-platform-2014.2.0.0-RC2.tar.gz
   - source repo: haskell/haskell-platform at 2014.2.0.0-RC2
   - windows 32bit: hskellPlatform-2014.2.0.0-i386-RC2-setup.exe
   - windows 64bit:hskellPlatform-2014.2.0.0-x86_64-RC2-setup.exe
   - os x 64bit: Haskell Platform 2014.2.0.0 64bit RC2.signed.pkg
   - travis-ci build: haskell/haskell-platform

*Short Notes for RC2, read these if nothing else:*


   - includes GHC 7.8.3
   - includes long awaited updates to OpenGL & GLUT packages
   - most other packages brought up to date (or nearly so)
   - website is still woefully out of date... will work on it this week


*Extra thanks to Randy Polen for burning the midnight-oil to get ths out*

   - removed unneeded python (et al) files from the GHC bindist for 64-bit
   Windows (referenced in GHC ticket #9014
   - added HTML "view source" pages for the GHC packages that was missing
   from the GHC bindist for both 32- and 64-bit Windows.

*Mac OS X*

*If you installed RC1 or older versions of the platform, you can remove
them first with the command  *sudo uninstall-hs only 7.8.3 --remove *Run it
without *--remove* to see what it will do first, it if you like. You can
also just install this one right on top of RC1. If you have older 7.8.3
installs from other distributions (bindist, built from src, etc...) you may
want to manually remove them first... YMMV.**. Yoda says: "When doubt you
have, the $PATH examine, you must!"*

   - works on 10.6! and 10.7, 10.8, and 10.9; with gcc or clang based Xcodes
   - works on 10.10!!! (Yosemite, developer preview 4 release)
   - works with clang out of the box, and haddock build issues with clang,
   fixed. *N.B.: If you have hand installed cabal 1.20, please be sure it
   uses Cabal to fix the haddock issue. The platform on OS X includes
   cabal 1.18, using, which fixes the problem.*

*Source tarball*

   - uses new build machinery... all the kinks may not be worked out, and
   not all build featuers (notably a --prefix command) are implemented yet.
   This doesn't affect the content of the Platform, though.
   - generic *nix builds, and specific distribution builds are forth coming
   (though feel free to chip in and help!)

*Longer Notes for RC2:*


   - Built with the new shake based build system
   - cgi package not included as it doesn't build under 7.8, and no word
   from the maintainer in quite some time
   - hscolour is included as a tool, mostly as it is used to build the
   platform itself on win and mac... but technically it isn't part of the
   - the haskell-platform package itself is not in these releases... it
   never contained anything other than dependencies.


   - The Haskell Platform now provides a native Windows 64-bit installation
   (haskell-platform issue #54
   - All included packages built without --enable-split-objs (GHC 7.8 FAQ
   - All included packages built without --enable-shared (GHC ticket #8228
   - If other Haskell Platform installations are detected during the
   installation of Haskell Platform 2014.2.0.0, a warning is displayed to the
   user that this is not recommended since problems will arise due to how the
   PATH is used in many cases to find ancillary build tools
   - Using ghci to build an executable that links against a DLL may result
   in numerous warnings about symbols (GHC ticket #9297
   - The Haskell Platform for Windows, both 32-bit and 64-bit, now includes
   an updated version of the OpenGL Utility Toolkit (GLUT) from the FreeGLUT
   project, utilizing the pre-built distribution from
   http://www.transmissionzero.co.uk/software/freeglut-devel/ with the
   MinGW build (freeglut-MinGW-2.8.1-1.mp.zip). (haskell-platform issue #81

*Mac OS X*

   - file layout on the Mac has improved. In particular, executables are
   now installed directly in $prefix/bin dirs, rather than within the package
   - Distributed with a build of 7.8.3 that differs from the released
   bindist in two ways: a) it was built split-objs for smaller resulting
   executables, b) it includes Cabal- which fixes a particularly nasty
   problem with haddock, -XCPP, and clang based systems. This ghc-7.8.3
   bindist is available as well:
      - ghc-7.8.3-x86_64-apple-darwin-r3.tar.bz2
      - haddocks finally cross link between packages correctly
   - includes a new experimental activate-hs command that can switch
   between multiple installed versions of the platform
   - includes a slightly updated uninstall-hs command
   - the cabal command is wrapped to provide a smoother file layout on the
   Mac... the wrapping only updates the ~/.cabal/config file the first time
   you run it.. please pay attention to its output - if you have a custom
   config file, you'll want to update it, as Cabal's defaults have changed


   - End of this week (from my vacation, I'll point out), we'll declare
   success and rename the files.
