In addition to numerous new and upgraded packages, this release has
the following highlights:

<listitem>
<para>
The <link xlink:href="http://haskell.org/">Haskell</link>
packages infrastructure has been re-designed from the ground up
(&quot;Haskell NG&quot;). 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="https://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 xlink:href="http://www.stackage.org/">LTS
Haskell</link> release since version 0.0 as well as the most
recent <link xlink:href="http://www.stackage.org/">Stackage
Nightly</link> snapshot. The announcement
<link xlink:href="https://nixos.org/nix-dev/2015-September/018138.html">&quot;Full

When upgrading from a previous release, please be aware of the

<itemizedlist spacing="compact">

<literal>sshd</literal> no longer supports DSA and ECDSA host

<programlisting language="bash">
{
system.stateVersion = &quot;14.12&quot;;

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

<para>
<literal>cron</literal> is no longer enabled by default, unless

<literal>cron</literal> to be enabled, set
<literal>services.cron.enable = true</literal>.
</para>

Steam now doesn't need root rights to work. Instead of using

package was renamed to <literal>steam</literal>, and old
<literal>steam</literal> package -- to

The CUPS printing service has been updated to version

Local printers are no longer shared or advertised by default.
This behavior can be changed by enabling
<literal>services.printing.defaultShared</literal> or
<literal>services.printing.browsing</literal> respectively.

The VirtualBox host and guest options have been named more

&quot;<literal>nix-env -qa</literal>&quot; 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 xlink:href="https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure">User's
Guide to the Haskell Infrastructure</link> provides more
information about this subject.

All Haskell builds that have been generated with version 1.x of
the <literal>cabal2nix</literal> utility are now invalid and
need to be re-generated with a current version of

version of this tool can be installed by running
<literal>nix-env -i cabal2nix</literal>.
</para>

<para>
The <literal>haskellPackages</literal> set in Nixpkgs used to
have a function attribute called <literal>extension</literal>
that users could override in their
<literal>~/.nixpkgs/config.nix</literal> files to configure
additional attributes, etc. That function still exists, but it's
now called <literal>overrides</literal>.

<para>
The OpenBLAS library has been updated to version
<literal>0.2.14</literal>. Support for the
<literal>x86_64-darwin</literal> platform was added. Dynamic
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.

<para>
The <literal>locate</literal> service no longer indexes the Nix

versions from cluttering the output. Indexing the store can be
activated by setting
<literal>services.locate.includeStore = true</literal>.
</para>
</listitem>
<listitem>
<para>
The Nix expression search path (<literal>NIX_PATH</literal>) no

Any use of module arguments such as <literal>pkgs</literal> to
access library functions, or to define
<literal>imports</literal> attributes will now lead to an
infinite loop at the time of the evaluation.
</para>
<para>
In case of an infinite loop, use the
<literal>--show-trace</literal> command line argument and read
the line just above the error message.
</para>

<para>
Any use of <literal>pkgs.lib</literal>, should be replaced by
<literal>lib</literal>, after adding it as argument of the

When <literal>pkgs</literal> is used to download other projects
