Hello everyone,
The GHC team is pleased to announce the availability of GHC 8.4.4, a
patch-level release in the 8.4 series. The source distribution, binary
distributions, and documentation for this release are available at
https://downloads.haskell.org/~ghc/8.4.4
This release fixes several bugs present in 8.4.3 These include,
- A bug which could result in memory unsafety with certain uses of
`touch#` has been resolved. (#14346)
- A compiler panic triggered by some GADT record updates has been
fixed (#15499)
- The `text` library has been updated, fixing several serious bugs in
the version shipped with GHC 8.4.3 (see `text` issues #227, #221,
and #197.
- A serious code generation bug in the LLVM code generation,
potentially resulting in incorrect evaluation of floating point
expressions, has been fixed (#14251)
As always, the full release notes can be found in the users guide,
https://downloads.haskell.org/~ghc/8.4.4/docs/html/users_guide/8.4.4-notes.html
Thanks to everyone who has contributed to developing, documenting, and
testing this release!
As always, let us know if you encounter trouble.
How to get it
~~~~~~~~~~~~~
The easy way is to go to the web page, which should be self-explanatory:
https://www.haskell.org/ghc/
We supply binary builds in the native package format for many
platforms, and the source distribution is available from the same
place.
Packages will appear as they are built - if the package for your
system isn't available yet, please try again later.
Background
~~~~~~~~~~
Haskell is a standard lazy functional programming language.
GHC is a state-of-the-art programming suite for Haskell. Included is
an optimising compiler generating efficient code for a variety of
platforms, together with an interactive system for convenient, quick
development. The distribution includes space and time profiling
facilities, a large collection of libraries, and support for various
language extensions, including concurrency, exceptions, and foreign
language interfaces. GHC is distributed under a BSD-style open source license.
A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page (see below).
