The GHC team is pleased to announce the second and likely last alpha
release of GHC 8.8.1. The source distribution, binary distributions, and
documentation are available at
A draft of the release notes is also available .
This release is the culmination of over 3000 commits by over one hundred
contributors and has several new features and numerous bug fixes
relative to GHC 8.6:
* Profiling now works correctly on 64-bit Windows (although still may
be problematic on 32-bit Windows due to platform limitations; see
* A new code layout algorithm for amd64's native code generator
* The introduction of a late lambda-lifting pass which may reduce
allocations significantly for some programs.
* Further work on Trees That Grow, enabling improved code re-use of the
Haskell AST in tooling
* More locations where users can write `forall` (GHC Proposal #0007)
* Further work on the Hadrian build system
This release brings a number of fixes since alpha 1:
* A number of linker fixes (#16779, #16784)
* The process, binary, Cabal, time, terminfo libraries have all been
bumped to their final release versions
* A regression rendering TemplateHaskell unusable in cross-compiled
configurations has been fixed (#16331)
* A regression causing compiler panics on compilation of some programs
has been fixed (#16449)
* -Wmissing-home-modules now handles hs-boot files correctly (#16551)
* A regression causing some programs to fail at runtime has been fixed
Due to on-going work on our release and testing infrastructure this
cycle is proceeding at a pace significantly slower than expected.
However, we anticipate that this investment will allow us to release a
more reliable, easier-to-install compiler on the planned six-month
release cadence in the future.
As always, if anything looks amiss do let us know.
