<title>Backward Incompatibilities</title>
<para>
When upgrading from a previous release, please be aware of the following
incompatible changes:
</para>
<itemizedlist>
<listitem>
<para>
Buildbot no longer supports Python 2, as support was dropped upstream in
version 2.0.0. Configurations may need to be modified to make them
compatible with Python 3.
</para>
</listitem>
<listitem>
<para>
PostgreSQL now uses
<filename class="directory">/run/postgresql</filename> as its socket
directory instead of <filename class="directory">/tmp</filename>. So
if you run an application like eg. Nextcloud, where you need to use
the Unix socket path as the database host name, you need to change it
accordingly.
</para>
</listitem>
<listitem>
<para>
The options <option>services.prometheus.alertmanager.user</option> and
<option>services.prometheus.alertmanager.group</option> have been removed
because the alertmanager service is now using systemd's <link
xlink:href="http://0pointer.net/blog/dynamic-users-with-systemd.html">
DynamicUser mechanism</link> which obviates these options.
</para>
</listitem>
<listitem>
<para>
The NetworkManager systemd unit was renamed back from network-manager.service to
NetworkManager.service for better compatibility with other applications expecting this name.
The same applies to ModemManager where modem-manager.service is now called ModemManager.service again.
</para>
</listitem>
<listitem>
<para>
The <option>services.nzbget.configFile</option> and <option>services.nzbget.openFirewall</option>
options were removed as they are managed internally by the nzbget. The
<option>services.nzbget.dataDir</option> option hadn't actually been used by
the module for some time and so was removed as cleanup.
</para>
</listitem>
<listitem>
<para>
The <option>services.emby.enable</option> module has been removed, see
<option>services.jellyfin.enable</option> instead for a free software fork of Emby.
See the Jellyfin documentation:

<para>
The option <option>systemd.network.networks.<name>.routes.*.routeConfig.GatewayOnlink</option>
was renamed to <option>systemd.network.networks.<name>.routes.*.routeConfig.GatewayOnLink</option>
(capital <literal>L</literal>). This follows

As of this release the NixOps feature <literal>autoLuks</literal> is deprecated. It no longer works
with our systemd version without manual intervention.
</para>
<para>
Whenever the usage of the module is detected the evaluation will fail with a message
explaining why and how to deal with the situation.
</para>
<para>
A new knob named <literal>nixops.enableDeprecatedAutoLuks</literal>
has been introduced to disable the eval failure and to acknowledge the notice was received and read.
If you plan on using the feature please note that it might break with subsequent updates.
</para>
<para>
Make sure you set the <literal>_netdev</literal> option for each of the file systems referring to block
devices provided by the autoLuks module. Not doing this might render the system in a
state where it doesn't boot anymore.
</para>
<para>
If you are actively using the <literal>autoLuks</literal> module please let us know in

<title>Other Notable Changes</title>

<listitem>
<para>
The <option>documentation</option> module gained an option named
<option>documentation.nixos.includeAllModules</option> which makes the
generated <citerefentry>
<refentrytitle>configuration.nix</refentrytitle>
<manvolnum>5</manvolnum></citerefentry> manual page include all options
from all NixOS modules included in a given
<literal>configuration.nix</literal> configuration file. Currently, it is
set to <literal>false</literal> by default as enabling it frequently
prevents evaluation. But the plan is to eventually have it set to
<literal>true</literal> by default. Please set it to
<literal>true</literal> now in your <literal>configuration.nix</literal>
and fix all the bugs it uncovers.
</para>
</listitem>
<listitem>
<para>
The <literal>vlc</literal> package gained support for Chromecast
streaming, enabled by default. TCP port 8010 must be open for it to work,
so something like <literal>networking.firewall.allowedTCPPorts = [ 8010
];</literal> may be required in your configuration. Also consider enabling
<link xlink:href="https://nixos.wiki/wiki/Accelerated_Video_Playback">
Accelerated Video Playback</link> for better transcoding performance.
</para>
</listitem>
<listitem>
<para>
The following changes apply if the <literal>stateVersion</literal> is
changed to 19.09 or higher. For <literal>stateVersion = "19.03"</literal>
or lower the old behavior is preserved.
</para>
<itemizedlist>
<listitem>

<literal>solr.package</literal> defaults to
<literal>pkgs.solr_8</literal>.

<listitem>
<para>
The <literal>hunspellDicts.fr-any</literal> dictionary now ships with <literal>fr_FR.{aff,dic}</literal>
which is linked to <literal>fr-toutesvariantes.{aff,dic}</literal>.
</para>
</listitem>
<listitem>
<para>
With the upgrade to systemd version 242 the <literal>systemd-timesyncd</literal>
service is no longer using <literal>DynamicUser=yes</literal>. In order for the
upgrade to work we rely on an activation script to move the state from the old
to the new directory. The older directory (prior <literal>19.09</literal>) was
<literal>/var/lib/private/systemd/timesync</literal>.
</para>
<para>
As long as the <literal>system.config.stateVersion</literal> is below
<literal>19.09</literal> the state folder will migrated to its proper location
(<literal>/var/lib/systemd/timesync</literal>), if required.
