-  This is the second stable release branch of NixOS. In addition to numerous

-     Systemd has been updated to version 212, which has
-     <link xlink:href="http://cgit.freedesktop.org/systemd/systemd/plain/NEWS?id=v212">numerous
-     improvements</link>. NixOS now automatically starts systemd user instances
-     when you log in. You can define global user units through the
-     <option>systemd.unit.*</option> options.

-     NixOS now supports fully declarative management of users and groups. If
-     you set <option>users.mutableUsers</option> to <literal>false</literal>,
-     then the contents of <filename>/etc/passwd</filename> and
-     <filename>/etc/group</filename> will be
-     <link
-  xlink:href="https://www.usenix.org/legacy/event/lisa02/tech/full_papers/traugott/traugott_html/">congruent</link>
-     to your NixOS configuration. For instance, if you remove a user from
-     <option>users.extraUsers</option> and run
-     <command>nixos-rebuild</command>, the user account will cease to exist.
-     Also, imperative commands for managing users and groups, such as
-     <command>useradd</command>, are no longer available. If
-     <option>users.mutableUsers</option> is <literal>true</literal> (the
-     default), then behaviour is unchanged from NixOS 13.10.

-    <para>
-     NixOS now has basic container support, meaning you can easily run a NixOS
-     instance as a container in a NixOS host system. These containers are
-     suitable for testing and experimentation but not production use, since
-     they’re not fully isolated from the host. See
-     <xref linkend="ch-containers"/> for details.

-    <para>
-     Systemd units provided by packages can now be overridden from the NixOS
-     configuration. For instance, if a package <literal>foo</literal> provides
-     systemd units, you can say:
-<programlisting>
-systemd.packages = [ pkgs.foo ];
-</programlisting>
-     to enable those units. You can then set or override unit options in the
-     usual way, e.g.
-<programlisting>
-systemd.services.foo.wantedBy = [ "multi-user.target" ];
-systemd.services.foo.serviceConfig.MemoryLimit = "512M";
-</programlisting>

-  When upgrading from a previous release, please be aware of the following
-  incompatible changes:
-  <itemizedlist>
-   <listitem>
-    <para>
-     Nixpkgs no longer exposes unfree packages by default. If your NixOS
-     configuration requires unfree packages from Nixpkgs, you need to enable
-     support for them explicitly by setting:
-<programlisting>
-nixpkgs.config.allowUnfree = true;
-</programlisting>
-     Otherwise, you get an error message such as:
-<screen>
-error: package ‘nvidia-x11-331.49-3.12.17’ in ‘…/nvidia-x11/default.nix:56’
-  has an unfree license, refusing to evaluate
-</screen>
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     The Adobe Flash player is no longer enabled by default in the Firefox and
-     Chromium wrappers. To enable it, you must set:
-<programlisting>
-nixpkgs.config.allowUnfree = true;
-nixpkgs.config.firefox.enableAdobeFlash = true; # for Firefox
-nixpkgs.config.chromium.enableAdobeFlash = true; # for Chromium
-</programlisting>
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     The firewall is now enabled by default. If you don’t want this, you need
-     to disable it explicitly:
-<programlisting>
-networking.firewall.enable = false;
-</programlisting>
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     The option <option>boot.loader.grub.memtest86</option> has been renamed to
-     <option>boot.loader.grub.memtest86.enable</option>.
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     The <literal>mysql55</literal> service has been merged into the
-     <literal>mysql</literal> service, which no longer sets a default for the
-     option <option>services.mysql.package</option>.
-    </para>
-   </listitem>
-   <listitem>
-    <para>
-     Package variants are now differentiated by suffixing the name, rather than
-     the version. For instance, <filename>sqlite-3.8.4.3-interactive</filename>
-     is now called <filename>sqlite-interactive-3.8.4.3</filename>. This
-     ensures that <literal>nix-env -i sqlite</literal> is unambiguous, and that
-     <literal>nix-env -u</literal> won’t “upgrade”
-     <literal>sqlite</literal> to <literal>sqlite-interactive</literal> or vice
-     versa. Notably, this change affects the Firefox wrapper (which provides
-     plugins), as it is now called <literal>firefox-wrapper</literal>. So when
-     using <command>nix-env</command>, you should do <literal>nix-env -e
-     firefox; nix-env -i firefox-wrapper</literal> if you want to keep using
-     the wrapper. This change does not affect declarative package management,
-     since attribute names like <literal>pkgs.firefoxWrapper</literal> were
-     already unambiguous.

-     The symlink <filename>/etc/ca-bundle.crt</filename> is gone. Programs
-     should instead use the environment variable
-     <envar>OPENSSL_X509_CERT_FILE</envar> (which points to
-     <filename>/etc/ssl/certs/ca-bundle.crt</filename>).
