=============================================================
The (Interactive) Glasgow Haskell Compiler -- version 7.2.1
The (Interactive) Glasgow Haskell Compiler -- version 7.2.2
=============================================================
The GHC Team is pleased to announce a new major release of GHC, 7.2.1.
The GHC Team is pleased to announce a new bugfix release of GHC, 7.2.2.
The 7.2 branch is intended to be more of a "technology preview" than
normal GHC stable branches; in particular, it supports a significantly
improved version of DPH, as well as new features such as compiler
plugins and "safe Haskell". The design of these new features may evolve
as we get more experience with them. See the release notes for more
details of what's new and what's changed.
as we get more experience with them.
We are also using this branch as an opportunity to work out the best
workflows to use with git.
The changes in this release, relative to 7.2.1, are:
We expect the 7.2 branch to be short-lived, with 7.4.1 coming out
shortly after ICFP as normal.
* All packages are now trusted by default. If you wish to make use
of Safe Haskell, you will need to manually untrust packages that
you do not wish to trust.
* An optimiser bug which can cause segfaults has been fixed.
Full release notes are here:
* A native code generator bug which can cause segfaults on x86 and
amd64 has been fixed.
* A race condition in the runtime system that can cause segfaults
has been fixed.
* Exception handlers are now run in the mask state, rather than the
maskUninterruptible state. Fixes a bug that could cause the GHCi
debugger to hang amongst other things.
* The shutdownHaskellAndExit function now immediately exits, even
if hs_init has been called multiple times.
* A bug arising when using type signature declarations in Template
Haskell splices has been fixed.
* A bug arising when using class instances in Template Haskell
splices has been fixed.
* Incorrectly encoded text at the end of a file is now handled
correctly.
* The base package is now version 4.4.1.0 (was 4.4.0.0).
* Haddock is now version 2.9.4.
