When upgrading from a previous release, please be aware of the following
incompatible changes:
</para>
<itemizedlist>
<listitem>
<para>
<literal>systemd-journal2gelf</literal> no longer parses json and expects the receiving system to handle it. How to achieve this with Graylog is described in this <link xlink:href="https://github.com/parse-nl/SystemdJournal2Gelf/issues/10">GitHub issue</link>.
</para>
</listitem>
<listitem>
<para>
If the <varname>services.dbus</varname> module is enabled, then
the user D-Bus session is now always socket activated. The
associated options <varname>services.dbus.socketActivated</varname>
and <varname>services.xserver.startDbusSession</varname> have
therefore been removed and you will receive a warning if
they are present in your configuration. This change makes the
user D-Bus session available also for non-graphical logins.
</para>
</listitem>
<listitem>
<para>
The option <option>fonts.enableFontDir</option> has been renamed to
<xref linkend="opt-fonts.fontDir.enable"/>. The path of font directory
has also been changed to <literal>/run/current-system/sw/share/X11/fonts</literal>,
for consistency with other X11 resources.
</para>
</listitem>
<listitem>
<para>
A number of options have been renamed in the kicad interface. <literal>oceSupport</literal>
has been renamed to <literal>withOCE</literal>, <literal>withOCCT</literal> has been renamed
to <literal>withOCC</literal>, <literal>ngspiceSupport</literal> has been renamed to
<literal>withNgspice</literal>, and <literal>scriptingSupport</literal> has been renamed to
<literal>withScripting</literal>. Additionally, <literal>kicad/base.nix</literal> no longer
provides default argument values since these are provided by
<literal>kicad/default.nix</literal>.

<para>
The socket for the <literal>pdns-recursor</literal> module was moved from <literal>/var/lib/pdns-recursor</literal>
to <literal>/run/pdns-recursor</literal> to match upstream.
</para>
</listitem>
<listitem>
<para>
PowerDNS has been updated from <literal>4.2.x</literal> to <literal>4.3.x</literal>. Please
be sure to review the <link xlink:href="https://doc.powerdns.com/authoritative/upgrading.html#x-to-4-3-0">Upgrade Notes</link>
provided by upstream before upgrading. Worth specifically noting is that the service now runs
entirely as a dedicated <literal>pdns</literal> user, instead of starting as <literal>root</literal>
and dropping privileges, as well as the default <literal>socket-dir</literal> location changing from
<literal>/var/lib/powerdns</literal> to <literal>/run/pdns</literal>.

The default-version of <literal>nextcloud</literal> is <package>nextcloud20</package>.
Please note that it's <emphasis>not</emphasis> possible to upgrade <literal>nextcloud</literal>
across multiple major versions! This means that it's e.g. not possible to upgrade
from <package>nextcloud18</package> to <package>nextcloud20</package> in a single deploy.
</para>
<para>
The package can be manually upgraded by setting <xref linkend="opt-services.nextcloud.package" />
to <package>nextcloud20</package>.

<listitem>
<para>
NixOS now emits a deprecation warning if systemd's <literal>StartLimitInterval</literal> setting is used in a <literal>serviceConfig</literal> section instead of in a <literal>unitConfig</literal>; that setting is deprecated and now undocumented for the service section by systemd upstream, but still effective and somewhat buggy there, which can be confusing. See <link xlink:href="https://github.com/NixOS/nixpkgs/issues/45785">#45785</link> for details.
</para>
<para>
All services should use <xref linkend="opt-systemd.services._name_.startLimitIntervalSec" /> or <literal>StartLimitIntervalSec</literal> in <xref linkend="opt-systemd.services._name_.unitConfig" /> instead.
