<title>Release 17.09 (“Hummingbird”, 2017/09/??)</title>
<para>In addition to numerous new and upgraded packages, this release
has the following highlights: </para>
<itemizedlist>
<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>
<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>
The ipfs package 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>

The <literal>caddy</literal> service was previously using an extra
<literal>.caddy</literal> in the data directory specified with the

<literal>dataDir</literal>.

<para>
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>
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.
