Ben Gamari - 2018-05-29
Hello everyone,
The GHC team is pleased to announce the availability of GHC 8.4.3. The source distribution, binary distributions, and documentation for this release are available here.
This release includes a few bug fixes including:
A code generation bug resulting in crashing of some programs using
UnboxedSums
has been fixed (#15038).#14381, where Cabal and GHC would disagree about
abi-depends
, resulting in build failures, has been worked around. Note that the work-around patch has already been shipped by several distributions in previous releases, so this change may not be visible to you.By popular demand, GHC now logs a message when it reads a package environment file, hopefully eliminating some of the confusion wrought by this feature.
GHC now emits assembler agreeable to newer versions of Gnu binutils, fixing #15068.
SmallArray#
s can now be compacted into a compact region
Thanks to everyone who has contributed to developing, documenting, and testing this release!
As always, let us know if you encounter trouble.
