<title>Highlights</title>
<para>
In addition to numerous new and upgraded packages, this release has the
following highlights:
</para>
<itemizedlist>
<listitem>
<para>
The GNOME version is now 3.24. KDE Plasma was upgraded to 5.10, KDE
Applications to 17.08.1 and KDE Frameworks to 5.37.
</para>
</listitem>
<listitem>
<para>
The user handling now keeps track of deallocated UIDs/GIDs. When a user or
group is revived, this allows it to be allocated the UID/GID it had
before. A consequence is that UIDs and GIDs are no longer reused.
</para>
</listitem>
<listitem>
<para>
The module option <option>services.xserver.xrandrHeads</option> now causes
the first head specified in this list to be set as the primary head. Apart
from that, it's now possible to also set additional options by using an
attribute set, for example:
<programlisting>
{ services.xserver.xrandrHeads = [
"HDMI-0"
{
output = &quot;DVI-0&quot;;
primary = true;
monitorConfig = ''
Option &quot;Rotate&quot; &quot;right&quot;
'';
}
];
}
</programlisting>
This will set the <literal>DVI-0</literal> output to be the primary head,
even though <literal>HDMI-0</literal> is the first head in the list.
</para>
</listitem>
<listitem>
<para>
The handling of SSL in the <literal>services.nginx</literal> module has
been cleaned up, renaming the misnamed <literal>enableSSL</literal> to
<literal>onlySSL</literal> which reflects its original intention. This is
not to be used with the already existing <literal>forceSSL</literal> which
creates a second non-SSL virtual host redirecting to the SSL virtual host.
This by chance had worked earlier due to specific implementation details.
In case you had specified both please remove the
<literal>enableSSL</literal> option to keep the previous behaviour.
</para>
<para>
Another <literal>addSSL</literal> option has been introduced to configure
both a non-SSL virtual host and an SSL virtual host with the same
configuration.
</para>
<para>
Options to configure <literal>resolver</literal> options and
<literal>upstream</literal> blocks have been introduced. See their
information for further details.
</para>
<para>
The <literal>port</literal> option has been replaced by a more generic
<literal>listen</literal> option which makes it possible to specify
multiple addresses, ports and SSL configs dependant on the new SSL
handling mentioned above.

<title>Backward Incompatibilities</title>
<para>
When upgrading from a previous release, please be aware of the following
incompatible changes:
</para>
<itemizedlist>
<listitem>
<para>
<emphasis role="strong"> In an Qemu-based virtualization environment, the
network interface names changed from i.e. <literal>enp0s3</literal> to
<literal>ens3</literal>. </emphasis>
</para>
<para>
This is due to a kernel configuration change. The new naming is consistent
with those of other Linux distributions with systemd. See
<link xlink:href="https://github.com/NixOS/nixpkgs/issues/29197">#29197</link>
for more information.
</para>
<para>
A machine is affected if the <literal>virt-what</literal> tool either
returns <literal>qemu</literal> or <literal>kvm</literal>
<emphasis>and</emphasis> has interface names used in any part of its NixOS
configuration, in particular if a static network configuration with
<literal>networking.interfaces</literal> is used.
</para>
<para>
Before rebooting affected machines, please ensure:
<itemizedlist>
<listitem>
<para>
Change the interface names in your NixOS configuration. The first
interface will be called <literal>ens3</literal>, the second one
<literal>ens8</literal> and starting from there incremented by 1.
</para>
</listitem>
<listitem>
<para>
After changing the interface names, rebuild your system with
<literal>nixos-rebuild boot</literal> to activate the new configuration
after a reboot. If you switch to the new configuration right away you
might lose network connectivity! If using <literal>nixops</literal>,
deploy with <literal>nixops deploy --force-reboot</literal>.
</para>
</listitem>
</itemizedlist>
</para>
</listitem>
<listitem>
<para>
The following changes apply if the <literal>stateVersion</literal> is
changed to 17.09 or higher. For <literal>stateVersion = "17.03"</literal>
or lower the old behavior is preserved.
</para>
<itemizedlist>
<listitem>

The <literal>postgres</literal> default version was changed from 9.5 to
9.6.

<literal>root</literal> to <literal>postgres</literal> to more closely
follow what other Linux distributions are doing.
</para>

<listitem>
<para>
The <literal>postgres</literal> default <literal>dataDir</literal> has

Radicale's default package has changed from 1.x to 2.x. Instructions to
migrate can be found <link xlink:href="http://radicale.org/1to2/"> here
</link>. It is also possible to use the newer version by setting the
<literal>package</literal> to <literal>radicale2</literal>, which is
done automatically when <literal>stateVersion</literal> is 17.09 or
higher. The <literal>extraArgs</literal> option has been added to allow
passing the data migration arguments specified in the instructions; see
the
<filename xlink:href="https://github.com/NixOS/nixpkgs/blob/master/nixos/tests/radicale.nix">radicale.nix</filename>
NixOS test for an example migration.

<para>
The <literal>fanctl</literal> package and <literal>fan</literal> module

</para>
</listitem>
<listitem>
<para>
The <literal>ipfs</literal> service now doesn't ignore the
<literal>dataDir</literal> option anymore. If you've ever set this option
to anything other than the default you'll have to either unset it (so the
default gets used) or migrate the old data manually with
<programlisting>
dataDir=&lt;valueOfDataDir&gt;
mv /var/lib/ipfs/.ipfs/* $dataDir
rmdir /var/lib/ipfs/.ipfs
</programlisting>
</para>
</listitem>
<listitem>
<para>
The <literal>caddy</literal> service was previously using an extra
<literal>.caddy</literal> directory in the data directory specified with
the <literal>dataDir</literal> option. The contents of the
<literal>.caddy</literal> directory are now expected to be in the
<literal>dataDir</literal>.
</para>
</listitem>
<listitem>
<para>
The <literal>ssh-agent</literal> user service is not started by default
anymore. Use <literal>programs.ssh.startAgent</literal> to enable it if
needed. There is also a new <literal>programs.gnupg.agent</literal> module
that creates a <literal>gpg-agent</literal> user service. It can also
serve as a SSH agent if <literal>enableSSHSupport</literal> is set.
</para>
</listitem>
<listitem>
<para>
The <literal>services.tinc.networks.&lt;name&gt;.listenAddress</literal>
option had a misleading name that did not correspond to its behavior. It
now correctly defines the ip to listen for incoming connections on. To
keep the previous behaviour, use
<literal>services.tinc.networks.&lt;name&gt;.bindToAddress</literal>
instead. Refer to the description of the options for more details.
</para>

<para>
<literal>tlsdate</literal> package and module were removed. This is due to
the project being dead and not building with openssl 1.1.

<literal>wvdial</literal> package and module were removed. This is due to
the project being dead and not building with openssl 1.1.

</listitem>
<listitem>
<para>
<literal>cc-wrapper</literal>'s setup-hook now exports a number of
environment variables corresponding to binutils binaries, (e.g.
<envar>LD</envar>, <envar>STRIP</envar>, <envar>RANLIB</envar>, etc). This
is done to prevent packages' build systems guessing, which is harder to
predict, especially when cross-compiling. However, some packages have
broken due to this—their build systems either not supporting, or
claiming to support without adequate testing, taking such environment
variables as parameters.
</para>
</listitem>
<listitem>
<para>
<literal>services.firefox.syncserver</literal> now runs by default as a
non-root user. To accomodate this change, the default sqlite database
location has also been changed. Migration should work automatically. Refer
to the description of the options for more details.
</para>
</listitem>
<listitem>
<para>
The <literal>compiz</literal> window manager and package was removed. The
system support had been broken for several years.
</para>
</listitem>
<listitem>
<para>
Touchpad support should now be enabled through <literal>libinput</literal>
as <literal>synaptics</literal> is now deprecated. See the option
<literal>services.xserver.libinput.enable</literal>.
</para>
</listitem>
<listitem>
<para>
grsecurity/PaX support has been dropped, following upstream's decision to
cease free support. See
<link xlink:href="https://grsecurity.net/passing_the_baton.php">
upstream's announcement</link> for more information. No complete
replacement for grsecurity/PaX is available presently.
</para>
</listitem>
<listitem>
<para>
<literal>services.mysql</literal> now has declarative configuration of
databases and users with the <literal>ensureDatabases</literal> and
<literal>ensureUsers</literal> options.
</para>
<para>
These options will never delete existing databases and users, especially
not when the value of the options are changed.
</para>
<para>
The MySQL users will be identified using
<link xlink:href="https://mariadb.com/kb/en/library/authentication-plugin-unix-socket/">
Unix socket authentication</link>. This authenticates the Unix user with
the same name only, and that without the need for a password.
</para>
<para>
If you have previously created a MySQL <literal>root</literal> user
<emphasis>with a password</emphasis>, you will need to add
<literal>root</literal> user for unix socket authentication before using
the new options. This can be done by running the following SQL script:
<programlisting language="sql">
CREATE USER 'root'@'%' IDENTIFIED BY '';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
-- Optionally, delete the password-authenticated user:
-- DROP USER 'root'@'localhost';
</programlisting>
</para>
</listitem>
<listitem>
<para>
<literal>services.mysqlBackup</literal> now works by default without any
user setup, including for users other than <literal>mysql</literal>.
</para>
<para>
By default, the <literal>mysql</literal> user is no longer the user which
performs the backup. Instead a system account
<literal>mysqlbackup</literal> is used.
</para>
<para>
The <literal>mysqlBackup</literal> service is also now using systemd
timers instead of <literal>cron</literal>.
</para>
<para>
Therefore, the <literal>services.mysqlBackup.period</literal> option no
longer exists, and has been replaced with
<literal>services.mysqlBackup.calendar</literal>, which is in the format
of
<link
xlink:href="https://www.freedesktop.org/software/systemd/man/systemd.time.html#Calendar%20Events">systemd.time(7)</link>.
</para>
<para>
If you expect to be sent an e-mail when the backup fails, consider using a
script which monitors the systemd journal for errors. Regretfully, at
present there is no built-in functionality for this.
</para>
<para>
You can check that backups still work by running <command>systemctl start
mysql-backup</command> then <command>systemctl status
mysql-backup</command>.
</para>
</listitem>
<listitem>
<para>
Templated systemd services e.g <literal>container@name</literal> are now
handled currectly when switching to a new configuration, resulting in them
being reloaded.

Modules can now be disabled by using
<link
xlink:href="https://nixos.org/nixpkgs/manual/#sec-replace-modules">
disabledModules</link>, allowing another to take it's place. This can be
used to import a set of modules from another channel while keeping the
rest of the system on a stable release.
</para>
</listitem>
<listitem>
<para>
Updated to FreeType 2.7.1, including a new TrueType engine. The new engine
replaces the Infinality engine which was the default in NixOS. The default
font rendering settings are now provided by fontconfig-penultimate,
replacing fontconfig-ultimate; the new defaults are less invasive and
provide rendering that is more consistent with other systems and hopefully
with each font designer's intent. Some system-wide configuration has been
removed from the Fontconfig NixOS module where user Fontconfig settings
are available.
</para>
</listitem>
<listitem>
<para>
ZFS/SPL have been updated to 0.7.0, <literal>zfsUnstable,
splUnstable</literal> have therefore been removed.
</para>
</listitem>
<listitem>
<para>
The <option>time.timeZone</option> option now allows the value
<literal>null</literal> in addition to timezone strings. This value allows
changing the timezone of a system imperatively using <command>timedatectl
set-timezone</command>. The default timezone is still UTC.
</para>
</listitem>
<listitem>
<para>
Nixpkgs overlays may now be specified with a file as well as a directory.
The value of <literal>&lt;nixpkgs-overlays></literal> may be a file, and
<filename>~/.config/nixpkgs/overlays.nix</filename> can be used instead of
the <filename>~/.config/nixpkgs/overlays</filename> directory.
</para>
<para>
See the overlays chapter of the Nixpkgs manual for more details.

declaratively with <literal>networking.hosts</literal>.
</para>

<listitem>
<para>
Two new options have been added to the installer loader, in addition to
the default having changed. The kernel log verbosity has been lowered to
the upstream default for the default options, in order to not spam the
console when e.g. joining a network.
