Hello everyone,<br>
<br>
The GHC development team is very pleased to announce the first beta<br>
leading up to GHC 8.6.1 release. The usual release artifacts are<br>
available from<br>
<br>
<a href="https://downloads.haskell.org/~ghc/8.6.1-beta1" rel="noreferrer" target="_blank">https://downloads.haskell.org/<wbr>~ghc/8.6.1-beta1</a><br>
<br>
This beta fixes most of the bugs reported in the first two alphas and<br>
brings all of the core libraries up to their final release versions.<br>
<br>
The 8.6 release fixes over 300 bugs from the 8.4 series and introduces a<br>
number of exciting features. These most notably include:<br>
<br>
* Significantly better handling of macOS linker command size limits,<br>
avoiding linker errors while linking large projects<br>
<br>
* A new deriving mechanism, `deriving via`, providing a convenient way<br>
for users to extend Haskell's typeclass deriving mechanism<br>
<br>
* Quantified constraints, allowing forall quantification in contexts<br>
<br>
* An early version of the GHCi `:doc` command<br>
<br>
* The `ghc-heap-view` package, allowing introspection into the<br>
structure of GHC's heap<br>
<br>
* Valid hole fit hints, helping the user to find terms to fill typed<br>
holes in their programs<br>
<br>
* The BlockArguments extension, allowing the `$` operator to be omitted<br>
in some unambiguous contexts<br>
<br>
* The next phase of the MonadFail proposal, enabling<br>
-XMonadFailDesugaring by default<br>
<br>
A full list of the changes in this release can be found in the<br>
release notes:<br>

<a href="https://downloads.haskell.org/~ghc/8.6.1-beta1/docs/html/users_guide/8.6.1-notes.html" rel="noreferrer" target="_blank">https://downloads.haskell.org/<wbr>~ghc/8.6.1-beta1/docs/html/use<wbr>rs_guide/8.6.1-notes.html</a><br>
<br>
This will very likely be the last release before the final 8.6.1 so do<br>
give it a thorough testing and, as always, report any issues you<br>
encounter. Thanks for your help!<br>
<br>
Cheers,<br>
<br>
