===============================================
The Glasgow Haskell Compiler -- version 8.2.2
===============================================
The GHC Team is pleased to announce a new minor release of GHC. This release
builds on the performance and stability improvements of 8.2.1, fixing a variety
of correctness bugs, improving error messages, and making the compiler more
portable.
Notable bug-fixes include
* A correctness issue resulting in segmentation faults in some
FFI-users (#13707, #14346)
* A correctness issue resulting in undefined behavior in some programs
using STM (#14171)
* A bug which may have manifested in segmentation faults in
out-of-memory condition (#14329)
* clearBit of Natural no longer bottoms (#13203)
* A specialisation bug resulting in exponential blowup of compilation
time in some specialisation-intensive programs (#14379)
* ghc-pkg now works even in environments with misconfigured NFS mounts
(#13945)
* GHC again supports production of position-independent executables
(#13702)
* Better error messages around kind mismatches (#11198, #12373, #13530,
#13610)
A thorough list of the changes in the release can be found in the release
notes,
https://haskell.org/ghc/docs/8.2.2/html/users_guide/8.2.2-notes.html
How to get it
~~~~~~~~~~~~~
This release can be downloaded from
https://www.haskell.org/ghc/download_ghc_8_2_2.html
For older versions see
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.
Background
~~~~~~~~~~
Haskell is a standardized 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).
On-line GHC-related resources
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Relevant URLs:
GHC home page https://www.haskell.org/ghc/
GHC developers' home page https://ghc.haskell.org/trac/ghc/

Supported Platforms
~~~~~~~~~~~~~~~~~~~
The list of platforms we support, and the people responsible for them, is here:
https://gitlab.haskell.org/ghc/ghc/wikis/team-ghc
Ports to other platforms are possible with varying degrees of difficulty. The
Building Guide describes how to go about porting to a new platform:
https://gitlab.haskell.org/ghc/ghc/wikis/building
Developers
~~~~~~~~~~
We welcome new contributors. Instructions on accessing our source code
repository, and getting started with hacking on GHC, are available from the
GHC's developer's site:
https://ghc.haskell.org/trac/ghc/
Mailing lists
~~~~~~~~~~~~~
We run mailing lists for GHC users and bug reports; to subscribe, use the web
interfaces at
https://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users
https://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-tickets
There are several other haskell and ghc-related mailing lists on
www.haskell.org; for the full list, see
https://mail.haskell.org/cgi-bin/mailman/listinfo
Many GHC developers hang out on #haskell on IRC:
https://www.haskell.org/haskellwiki/IRC_channel
Please report bugs using our bug tracking system. Instructions on reporting bugs
can be found here:
