When upgrading from a previous release, please be aware of the following
incompatible changes:

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>
<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.

The <literal>ntp</literal> module now has sane default restrictions.
If you're relying on the previous defaults, which permitted all queries
and commands from all firewall-permitted sources, you can set
<varname>services.ntp.restrictDefault</varname> and
<varname>services.ntp.restrictSource</varname> to
<literal>[]</literal>.

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

Buildbot now supports Python 3 and its packages have been moved to

the Python 2 or 3 version of the package.

Options
<literal>services.znc.confOptions.networks.<replaceable>name</replaceable>.userName</literal> and

Package <literal>wasm</literal> has been renamed <literal>proglodyte-wasm</literal>. The package

When the <literal>nixpkgs.pkgs</literal> option is set, NixOS will no

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

Slurm introduces the new option

Network interface indiscriminate NixOS firewall options
(<literal>networking.firewall.allow*</literal>) are now preserved when also
setting interface specific rules such as <literal>networking.firewall.interfaces.en0.allow*</literal>.
These rules continue to use the pseudo device "default"
(<literal>networking.firewall.interfaces.default.*</literal>), and assigning
to this pseudo device will override the (<literal>networking.firewall.allow*</literal>)
options.

<para>
The <literal>nscd</literal> service now disables all caching of
<literal>passwd</literal> and <literal>group</literal> databases by
default. This was interferring with the correct functioning of the
<literal>libnss_systemd.so</literal> module which is used by
<literal>systemd</literal> to manage uids and usernames in the presence of
<literal>DynamicUser=</literal> in systemd services. This was already the
default behaviour in presence of <literal>services.sssd.enable =
true</literal> because nscd caching would interfere with
<literal>sssd</literal> in unpredictable ways as well. Because we're
using nscd not for caching, but for convincing glibc to find NSS modules
in the nix store instead of an absolute path, we have decided to disable
caching globally now, as it's usually not the behaviour the user wants and
can lead to surprising behaviour. Furthermore, negative caching of host
lookups is also disabled now by default. This should fix the issue of dns
lookups failing in the presence of an unreliable network.
</para>
<para>
If the old behaviour is desired, this can be restored by setting
the <literal>services.nscd.config</literal> option
with the desired caching parameters.

GitLab Shell previously used the nix store paths for the
<literal>gitlab-shell</literal> command in its
<literal>authorized_keys</literal> file, which might stop working after
garbage collection. To circumvent that, we regenerated that file on each
startup. As <literal>gitlab-shell</literal> has now been changed to use
<literal>/var/run/current-system/sw/bin/gitlab-shell</literal>, this is
not necessary anymore, but there might be leftover lines with a nix store
path. Regenerate the <literal>authorized_keys</literal> file via
<command>sudo -u git -H gitlab-rake gitlab:shell:setup</command> in that
case.

<para>
The <literal>pam_unix</literal> account module is now loaded with its
control field set to <literal>required</literal> instead of
<literal>sufficient</literal>, so that later pam account modules that
might do more extensive checks are being executed.
Previously, the whole account module verification was exited prematurely
in case a nss module provided the account name to
<literal>pam_unix</literal>.
The LDAP and SSSD NixOS modules already add their NSS modules when
enabled. In case your setup breaks due to some later pam account module
previosuly shadowed, or failing NSS lookups, please file a bug. You can
get back the old behaviour by manually setting
<literal><![CDATA[security.pam.services.<name?>.text]]></literal>.

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>.
