<para>When upgrading from a previous release, please be aware of the
following incompatible changes:

<itemizedlist>

<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:

rogramlisting>
rvices.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>. <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>

<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>. To choose
a different timezone for your system, configure
<literal>time.timeZone</literal> in
<literal>configuration.nix</literal>. A fairly complete list of possible
values for that setting is available at <link
xlink:href="https://en.wikipedia.org/wiki/List_of_tz_database_time_zones"/>.</para></listitem>

<listitem><para>GNU screen has been updated to 4.2.1, which breaks
the ability to connect to sessions created by older versions of
screen.</para></listitem>
