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

When upgrading from a previous release, please be aware of the
following incompatible changes:
</para>
<itemizedlist>
<listitem>
<para>
The default version of Apache httpd is now 2.4. If you use the
<literal>extraConfig</literal> 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:
</para>
<programlisting language="bash">
{
services.httpd.package = pkgs.apacheHttpd_2_2;
}
</programlisting>
</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-container-name</literal> rather than
<literal>c-container-name</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 <literal>rm -rf /tmp/.vbox*</literal>. The line
<literal>imports = [ <nixpkgs/nixos/modules/programs/virtualbox.nix> ]</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.
<literal>enablePepperPDF</literal> 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">https://en.wikipedia.org/wiki/List_of_tz_database_time_zones</link>.
</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>
<listitem>
<para>
The Intel GPU driver was updated to the 3.x prerelease version
(used by most distributions) and supports DRI3 now.
