incompatible changes:
</para>
<itemizedlist>
<listitem>
<para>
<literal>sound.enable</literal> now defaults to false.
</para>
</listitem>
<listitem>
<para>
Dollar signs in options under <option>services.postfix</option> are passed
verbatim to Postfix, which will interpret them as the beginning of a
parameter expression. This was already true for string-valued options in
the previous release, but not for list-valued options. If you need to pass
literal dollar signs through Postfix, double them.
</para>
</listitem>
<listitem>
<para>
The <literal>postage</literal> package (for web-based PostgreSQL
administration) has been renamed to <literal>pgmanage</literal>. The
corresponding module has also been renamed. To migrate please rename all
<option>services.postage</option> options to
<option>services.pgmanage</option>.

Package attributes starting with a digit have been prefixed with an

<emphasis role="strong"> The OpenSSH service no longer enables support for
DSA keys by default, which could cause a system lock out. Update your keys
or, unfavorably, re-enable DSA support manually. </emphasis>
</para>
<para>
DSA support was
<link xlink:href="https://www.openssh.com/legacy.html">deprecated in
OpenSSH 7.0</link>, due to it being too weak. To re-enable support, add
<literal>PubkeyAcceptedKeyTypes +ssh-dss</literal> to the end of your
<option>services.openssh.extraConfig</option>.
</para>
<para>
After updating the keys to be stronger, anyone still on a pre-17.03

</listitem>
<listitem>
<para>
The <literal>openssh</literal> package now includes Kerberos support by
default; the <literal>openssh_with_kerberos</literal> package is now a
deprecated alias. If you do not want Kerberos support, you can do
<literal>openssh.override { withKerberos = false; }</literal>. Note, this
also applies to the <literal>openssh_hpn</literal> package.
</para>
</listitem>
<listitem>
<para>
<literal>cc-wrapper</literal> has been split in two; there is now also a
<literal>bintools-wrapper</literal>. The most commonly used files in
<filename>nix-support</filename> are now split between the two wrappers.
Some commonly used ones, like
<filename>nix-support/dynamic-linker</filename>, are duplicated for
backwards compatability, even though they rightly belong only in
<literal>bintools-wrapper</literal>. Other more obscure ones are just
moved.
</para>
</listitem>
<listitem>
<para>
The propagation logic has been changed. The new logic, along with new
types of dependencies that go with, is thoroughly documented in the
"Specifying dependencies" section of the "Standard Environment" chapter of
the nixpkgs manual.
<!-- That's <xref linkend="ssec-stdenv-attributes"> were we to merge the manuals. -->
The old logic isn't but is easy to describe: dependencies were propagated
as the same type of dependency no matter what. In practice, that means
that many <function>propagatedNativeBuildInputs</function> should instead
be <function>propagatedBuildInputs</function>. Thankfully, that was and is
the least used type of dependency. Also, it means that some
<function>propagatedBuildInputs</function> should instead be
<function>depsTargetTargetPropagated</function>. Other types dependencies
should be unaffected.

<literal>lib.addPassthru drv passthru</literal> is removed. Use

The <literal>memcached</literal> service no longer accept dynamic socket
paths via <option>services.memcached.socket</option>. Unix sockets can be

The <varname>hardware.amdHybridGraphics.disable</varname> option was
removed for lack of a maintainer. If you still need this module, you may
wish to include a copy of it from an older version of nixos in your
imports.
</para>
</listitem>
<listitem>
<para>
The merging of config options for
<varname>services.postfix.config</varname> was buggy. Previously, if other
options in the Postfix module like
<varname>services.postfix.useSrs</varname> were set and the user set
config options that were also set by such options, the resulting config
wouldn't include all options that were needed. They are now merged
correctly. If config options need to be overridden,
<literal>lib.mkForce</literal> or <literal>lib.mkOverride</literal> can be
used.

When using <option>services.xserver.libinput</option> (enabled by default
in GNOME), it now handles all input devices, not just touchpads. As a
result, you might need to re-evaluate any custom Xorg configuration. In
particular, <literal>Option "XkbRules" "base"</literal> may result in
broken keyboard layout.

The <literal>piwik</literal> user was renamed to

automatically for files in the data directory. If you use unix socket
authentication, remember to give the new <literal>matomo</literal> user
