The minimum version of Nix required to evaluate Nixpkgs is now 2.0.
</para>
<itemizedlist>
<listitem>
<para>
For users of NixOS 18.03 and 19.03, NixOS defaults to Nix 2.0, but
supports using Nix 1.11 by setting <literal>nix.package =
pkgs.nix1;</literal>. If this option is set to a Nix 1.11 package, you
will need to either unset the option or upgrade it to Nix 2.0.
</para>
</listitem>
<listitem>
<para>
For users of NixOS 17.09, you will first need to upgrade Nix by setting
<literal>nix.package = pkgs.nixStable2;</literal> and run
<command>nixos-rebuild switch</command> as the <literal>root</literal>
user.
</para>
</listitem>
<listitem>
<para>
For users of a daemon-less Nix installation on Linux or macOS, you can
upgrade Nix by running <command>curl https://nixos.org/nix/install |
sh</command>, or prior to doing a channel update, running
<command>nix-env -iA nix</command>.
</para>
<para>
If you have already run a channel update and Nix is no longer able to
evaluate Nixpkgs, the error message printed should provide adequate
directions for upgrading Nix.
</para>
</listitem>
<listitem>
<para>
For users of the Nix daemon on macOS, you can upgrade Nix by running
<command>sudo -i sh -c 'nix-channel --update &amp;&amp; nix-env -iA
nixpkgs.nix'; sudo launchctl stop org.nixos.nix-daemon; sudo launchctl
start org.nixos.nix-daemon</command>.

The Syncthing state and configuration data has been moved from
<varname>services.syncthing.dataDir</varname> to the newly defined
<varname>services.syncthing.configDir</varname>, which default to
<literal>/var/lib/syncthing/.config/syncthing</literal>.
This change makes possible to share synced directories using ACLs
without Syncthing resetting the permission on every start.

<para>
The <literal>light</literal> module no longer uses setuid binaries, but
udev rules. As a consequence users of that module have to belong to the
<literal>video</literal> group in order to use the executable (i.e.
<literal>users.users.yourusername.extraGroups = ["video"];</literal>).
</para>

<para>
Buildbot now supports Python 3 and its packages have been moved to
<literal>pythonPackages</literal>. The options

<option>services.buildbot-worker.package</option> can be used to select
the Python 2 or 3 version of the package.

<para>
Options
<literal>services.znc.confOptions.networks.<replaceable>name</replaceable>.userName</literal> and
<literal>services.znc.confOptions.networks.<replaceable>name</replaceable>.modulePackages</literal>
were removed. They were never used for anything and can therefore safely be removed.
</para>

<para>
Package <literal>wasm</literal> has been renamed <literal>proglodyte-wasm</literal>. The package
<literal>wasm</literal> will be pointed to <literal>ocamlPackages.wasm</literal> in 19.09, so
make sure to update your configuration if you want to keep <literal>proglodyte-wasm</literal>
</para>

<para>
When the <literal>nixpkgs.pkgs</literal> option is set, NixOS will no
longer ignore the <literal>nixpkgs.overlays</literal> option. The old
behavior can be recovered by setting <literal>nixpkgs.overlays =
lib.mkForce [];</literal>.

Package <literal>consul-ui</literal> and passthrough <literal>consul.ui</literal> have been removed.

Make sure to move all files to the new directory or to set the option accordingly.
</para>
<para>
The slurmctld now runs as user <literal>slurm</literal> instead of <literal>root</literal>.

<literal>services.slurm.user = root</literal>.
</para>
<para>
The options <literal>services.slurm.nodeName</literal> and

The Kubernetes DNS addons, kube-dns, has been replaced with CoreDNS.
This change is made in accordance with Kubernetes making CoreDNS the official default
starting from
<link xlink:href="https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.11.md#sig-cluster-lifecycle">Kubernetes v1.11</link>.
Please beware that upgrading DNS-addon on existing clusters might induce
minor downtime while the DNS-addon terminates and re-initializes.
Also note that the DNS-service now runs with 2 pod replicas by default.
The desired number of replicas can be configured using:
<option>services.kubernetes.addons.dns.replicas</option>.
