<title>Backward Incompatibilities</title>
<para>When upgrading from a previous release, please be aware of the
following incompatible changes:</para>
<itemizedlist>
<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>.

<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
version is safe to jump to 17.03, as vetted

<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.

must be set to true.
</para>
</listitem>

<para>
The option <option>services.logstash.listenAddress</option> is now <literal>127.0.0.1</literal> by default.
