<para>The <link xlink:href="http://haskell.org/">Haskell</link>
|
|
packages infrastructure has been re-designed from the ground up
|
|
("Haskell NG"). NixOS now distributes the latest version
|
|
of every single package registered on <link
|
|
xlink:href="http://hackage.haskell.org/">Hackage</link> -- well in
|
|
excess of 8,000 Haskell packages. Detailed instructions on how to
|
|
use that infrastructure can be found in the <link
|
|
xlink:href="http://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure">User's
|
|
Guide to the Haskell Infrastructure</link>. Users migrating from an
|
|
earlier release may find helpful information below, in the list of
|
|
backwards-incompatible changes. Furthermore, we distribute 51(!)
|
|
additional Haskell package sets that provide every single <link

|

since version 0.0 as well as the most recent <link

<listitem><para><command>sshd</command> no longer supports DSA and ECDSA

host keys by default. If you have existing systems with such host keys

<programlisting>
|
|
system.stateVersion = "14.12";
|

The new option <option>system.stateVersion</option> ensures that
|
|
certain configuration changes that could break existing systems (such
|
|
as the <command>sshd</command> host key setting) will maintain
|
|
compatibility with the specified NixOS release. NixOps sets the state

version of existing deployments automatically.</para></listitem>

<listitem><para><command>cron</command> is no longer enabled by

<listitem><para>Steam now doesn't need root rights to work. Instead of using

<literal>steamChrootEnv</literal> package was renamed to <literal>steam</literal>,

"<literal>nix-env -qa</literal>" no longer discovers
|
|
Haskell packages by name. The only packages visible in the global
|
|
scope are <literal>ghc</literal>, <literal>cabal-install</literal>,
|
|
and <literal>stack</literal>, but all other packages are hidden. The
|
|
reason for this inconvenience is the sheer size of the Haskell
|
|
package set. Name-based lookups are expensive, and most
|
|
<literal>nix-env -qa</literal> operations would become much slower
|
|
if we'd add the entire Hackage database into the top level attribute
|
|
set. Instead, the list of Haskell packages can be displayed by

running:

Previous versions of NixOS came with a feature called
|
|
<literal>ghc-wrapper</literal>, a small script that allowed GHC to
|
|
transparently pick up on libraries installed in the user's profile. This
|
|
feature has been deprecated; <literal>ghc-wrapper</literal> was removed
|
|
from the distribution. The proper way to register Haskell libraries with
|
|
the compiler now is the <literal>haskellPackages.ghcWithPackages</literal>
|
|
function. The <link
|

The OpenBLAS library has been updated to version

architecture detection was enabled; OpenBLAS now selects

microarchitecture-optimized routines at runtime, so optimal

performance is achieved without the need to rebuild OpenBLAS

locally. OpenBLAS has replaced ATLAS in most packages which use an

optimized BLAS or LAPACK implementation.
