Pre-built +packages for Linux, FreeBSD, Solaris and Win32 are also available.

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, C++, whatever). + +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 at + + http://www.haskell.org/ + +GHC's Web page lives at + + http://www.haskell.org/ghc/ + What's new ============= -Release 2.09 contains some library changes that may break programs -using glasgow extensions. The main points: - - * PrimIO has been removed, replaced by IO in all places - (including the type of C calls). - * The types of IO and ST have changed, to make them more - efficient. This won't bite you unless you go digging - around in the IO or ST monads, which you shouldn't... - * Several extension libraries have been moved to be - compatible with Hugs. See - - ftp://haskell.org/pub/reid/libs971028/libs.html - - for the definitions of the new libraries. - * Several of the interfaces exported by GlaExts are deprecated, - as they have been moved into common libraries (ST for instance). - GlaExts will eventually contain only extensions that are - exclusive to GHC. - -We've also fixed several bugs, one space leak, and added better -handling of warnings (-W, -Wall and -Wnot flags). As usual, see the -release notes in the Users' Guide for the full story. +This should be a stable release. There have been many enhancements +since 4.06, and shed-loads of bug-fixes (one shed (imperial) ~ one ton +(US)). + +There are the following changes + + - New profiling subsystem, based on cost-centre stacks. + + - Working x86 native code generator: now it works properly, runs + about twice as fast as compiling via C, and is on a par for + run-time speed (except in FP-intensive programs). + + - Implicit parameters (i.e. dynamic scoping without the pain). + + - DEPRECATED pragma for marking obsolescent interfaces. + + - In the wake of hslibs, a new package system for + libraries. -package should now be used instead of -syslib. + + - Result type signatures work. + + - Many tiresome long-standing bugs and problems (e.g. the trace + problem) have been fixed. + + - Many error messages have been made more helpful and/or + accurate. + +For full details see the release notes: + + http://www.haskell.org/ghc/docs/4.08/set/release-4-08.html + Mailing lists ================ We run mailing lists for GHC users and bug reports; to subscribe, send -mail to majordomo@dcs.gla.ac.uk; the msg body should be: +mail to majordomo@haskell.org; the msg body should be: + + subscribe glasgow-haskell-{users,bugs} Your Name - subscribe glasgow-haskell- Your Name +or -Please send bug reports about GHC to glasgow-haskell-bugs@dcs.gla.ac.uk ; GHC -users hang out on glasgow-haskell-users@dcs.gla.ac.uk + subscribe cvs-ghc Your Name +Please send bug reports about GHC to glasgow-haskell-bugs@haskell.org; +GHC users hang out on glasgow-haskell-users@haskell.org.
