Thanks to everyone involved with the release!
It's a bit sad that we don't have DWARF bindists this time (we had those for
8.4.2 and 8.4.3). DWARF builds make debugging GHC much easier, and because
runtime panics also include stack traces in DWARF builds tickets reported for
those bindists tend to be more helpful.
Would it be possible to provide DWARF bindists at a later date?

Hello everyone,
The GHC team is pleased to announce the availability of GHC 8.6.1, the fourth major release in the GHC 8 series. The source distribution, binary distributions, and documentation for this release are available at
https://downloads.haskell.org/~ghc/8.6.1
The 8.6 release fixes over 400 bugs from the 8.4 series and introduces a number of exciting features. These most notably include:
* A new deriving mechanism, `deriving via`, providing a convenient way for users to extend Haskell's typeclass deriving mechanism
* Quantified constraints, allowing forall quantification in constraint contexts
* An early version of the GHCi `:doc` command
* The `ghc-heap-view` package, allowing introspection into the structure of GHC's heap
* Valid hole fit hints, helping the user to find terms to fill typed holes in their programs
* The BlockArguments extension, allowing the `$` operator to be omitted in some unambiguous contexts
* An exciting new plugin mechanism, source plugins, allowing plugins to inspect and modify a wide variety of compiler representations.
* Improved recompilation checking when plugins are used
* Significantly better handling of macOS linker command size limits, avoiding linker errors while linking large projects
* The next phase of the MonadFail proposal, enabling -XMonadFailDesugaring by default
A full list of the changes in this release can be found in the release notes:
https://downloads.haskell.org/~ghc/8.6.1/docs/html/users_guide/8.6.1-notes.h...
Perhaps of equal importance, GHC 8.6 is the second major release made under GHC's accelerated six-month release schedule and the first set of binary distributions built primarily using our new continuous integration scheme. While the final 8.6 release is around three weeks later than initially scheduled due to late-breaking bug reports, we expect that the 8.8 release schedule shouldn't be affected.
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:
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).
On-line GHC-related resources ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Supported Platforms ~~~~~~~~~~~~~~~~~~~
The list of platforms we support, and the people responsible for them, is here:

Ports to other platforms are possible with varying degrees of difficulty. The Building Guide describes how to go about porting to a new platform:

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 run by Trac:
