     If <option>users.mutableUsers</option> is enabled (the default), changes made to the declaration of a user or group will be correctly realised when running <command>nixos-rebuild</command>. For instance, removing a user specification from <filename>configuration.nix</filename> will cause the actual user account to be deleted. If <option>users.mutableUsers</option> is disabled, it is no longer necessary to specify UIDs or GIDs; if omitted, they are allocated dynamically.

   <listitem>
    <para>
     The default version of Apache httpd is now 2.4. If you use the <option>extraConfig</option> option to pass literal Apache configuration text, you may need to update it — see <link
xlink:href="http://httpd.apache.org/docs/2.4/upgrading.html">Apache’s documentation</link> for details. If you wish to continue to use httpd 2.2, add the following line to your NixOS configuration:
<programlisting>
services.httpd.package = pkgs.apacheHttpd_2_2;
</programlisting>
    </para>
   </listitem>
   <listitem>
    <para>
     PHP 5.3 has been removed because it is no longer supported by the PHP project. A <link
xlink:href="http://php.net/migration54">migration guide</link> is available.
    </para>
   </listitem>
   <listitem>
    <para>
     The host side of a container virtual Ethernet pair is now called <literal>ve-<replaceable>container-name</replaceable></literal> rather than <literal>c-<replaceable>container-name</replaceable></literal>.
    </para>
   </listitem>
   <listitem>
    <para>
     GNOME 3.10 support has been dropped. The default GNOME version is now 3.12.
    </para>
   </listitem>
   <listitem>
    <para>
     VirtualBox has been upgraded to 4.3.20 release. Users may be required to run <command>rm -rf /tmp/.vbox*</command>. The line <literal>imports = [ &lt;nixpkgs/nixos/modules/programs/virtualbox.nix&gt; ]</literal> is no longer necessary, use <literal>services.virtualboxHost.enable = true</literal> instead.
    </para>
    <para>
     Also, hardening mode is now enabled by default, which means that unless you want to use USB support, you no longer need to be a member of the <literal>vboxusers</literal> group.
    </para>
   </listitem>
   <listitem>
    <para>
     Chromium has been updated to 39.0.2171.65. <option>enablePepperPDF</option> is now enabled by default. <literal>chromium*Wrapper</literal> packages no longer exist, because upstream removed NSAPI support. <literal>chromium-stable</literal> has been renamed to <literal>chromium</literal>.
    </para>

   <listitem>
    <para>
     Python packaging documentation is now part of nixpkgs manual. To override the python packages available to a custom python you now use <literal>pkgs.pythonFull.buildEnv.override</literal> instead of <literal>pkgs.pythonFull.override</literal>.
    </para>
   </listitem>
   <listitem>
    <para>
     <literal>boot.resumeDevice = "8:6"</literal> is no longer supported. Most users will want to leave it undefined, which takes the swap partitions automatically. There is an evaluation assertion to ensure that the string starts with a slash.
    </para>
   </listitem>
   <listitem>
    <para>
     The system-wide default timezone for NixOS installations changed from <literal>CET</literal> to <literal>UTC</literal>.

A fairly complete list of possible values for that setting is available at <link
