Hello everyone, The GHC team is pleased to announce the release candidate for GHC 8.8.1. The source distribution, binary distributions, and documentation are available at
https://downloads.haskell.org/ghc/8.8.1-rc1
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
#15934)
* 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)
* A comprehensive audit of GHC's memory ordering barriers has been
performed, resulting in a number of fixes that should significantly
improve the reliability of programs on architectures with
weakly-ordered memory models (e.g. PowerPC, many ARM and AArch64
implementations).
* A long-standing linker limitation rendering GHCi unusable with
projects with cyclic symbol dependencies has been fixed (#13786)
* Further work on the Hadrian build system
* Numerous bug-fixes
As always, if anything looks amiss do let us know.
Happy compiling!
Cheers,
- Ben
