The (Interactive) Glasgow Haskell Compiler -- version 7.10.1
The GHC Team is pleased to announce a new major release of GHC. There
have been a number of significant changes since the last major
* Several new language features and changes have been implemented:
- Applicative is now a superclass of Monad and in the Prelude.
- Many prelude combinators have been generalized
- Static pointers
* GHC now has preliminary and experimental support for DWARF based debugging.
* `integer-gmp` has been completely rewritten.
* Type-checking plugins can now extend the type checker.
* Support for partial type signatures
* Many bugfixes and other performance improvements.
* Preliminary support for 'backpack' features like signatures.
* Typeable is now generated by default for all data types automatically.
We've also fixed a handful of issues reported since RC3:
- A bug in the call arity analysis that would result in invalid core
was fixed (#10176)
- A bug in the Win32 package causing it to fail to load was fixed (#10165)
- ghc-prim has (correctly) been bumped to version 0.4.0.0, to comply
with the PVP.
- Several libraries have been bumped to their latest available
versions after coordination.

How to get it
The easy way is to go to the web page, which should be self-explanatory:
We supply binary builds in the native package format for many
platforms, and the source distribution is available from the same
Packages will appear as they are built - if the package for your

Haskell is a standard lazy functional programming language.
GHC is a state-of-the-art programming suite for Haskell. Included is
an optimising compiler generating good code for a variety of
platforms, together with an interactive system for convenient, quick
development. The distribution includes space and time profiling
facilities, a large collection of libraries, and support for various
language extensions, including concurrency, exceptions, and foreign
language interfaces (C, whatever). GHC is distributed under a
BSD-style open source license.
A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page (see below).
