All releases of The Glasgow Haskell Compiler
Release Notes: A floating point regression in 7.0.3 affecting x86 has been fixed. The GHCi linker now handles partially stripped object files. This fixes loading the ghc package in ghci when it's been stripped, which is often the case in Linux distribution packages. A bug that caused bad results from getCPUTime, getClockTime, and getCurrentTime has been fixed. Several runtime system bugs were fixed. Incorrect directory permissions when installing have been fixed. Some improvements have been made to the new Cabal testsuite support.
Release Notes: GHC now defaults to the Haskell 2010 language standard. -fglasgow-exts is now deprecated in favour of the individual extension flags. On POSIX platforms, there is a new I/O manager. This release includes an LLVM code generator which, for certain code, can bring some nice performance improvements. The type checker has been overhauled. The inliner has been overhauled. Large parts of the runtime system have been overhauled. A more recent mingw is bundled on Windows.
Release Notes: This is a bugfix release.
Release Notes: There have been a number of significant changes since the last major release. Support for parallel execution was considerably improved. Dynamic linking is now supported on Linux. The I/O libraries are now Unicode-aware, so your Haskell programs should now handle text files containing non-ASCII characters without special effort. The package system has been made more robust by associating each installed package with a unique identifier based on its exposed ABI. There are a variety of small language changes.
Release Notes: Various bugfixes.
Release Notes: This is a bugfix release. Many bugs in the compiler, libraries, and build system have been fixed. However, most library APIs have not changed, so code that worked with 6.10.1 should continue to work with 6.10.2.
Release Notes: You can now use the -prof and -threaded flags together. Assorted updates and bugfixes were made.
No changes have been submitted for this release.
Release Notes: Haskell Program Coverage (hpc) support has been added to the compiler. GHCi now includes a debugger. The first phase of the base package split has been done. The code generator now uses pointer tagging (which should mean most code improves by 10-15%, and as a result the compiler is also faster).
Release Notes: SMP support and impredicative polymorphism were added. The libraries were split into core and extra. Many more changes were made.
