<title>Release 17.03 (“XXX”, 2017/03/??)</title>
<para>In addition to numerous new and upgraded packages, this release
has the following highlights: </para>
<itemizedlist>
<listitem>
<para>Nixpkgs is now extensible through overlays. See the <link
xlink:href="https://nixos.org/nixpkgs/manual/#sec-overlays-install">Nixpkgs
manual</link> for more information.</para>
</listitem>
<listitem>
<para>The setuid wrapper functionality now supports setting
capabilities.</para>
</listitem>
<listitem>
<para>X.org server uses branch 1.19. Due to ABI incompatibilities,
<literal>ati_unfree</literal> keeps forcing 1.17
and <literal>amdgpu-pro</literal> starts forcing 1.18.</para>
</listitem>
<listitem>
<para>PHP now defaults to PHP 7.1</para>
</listitem>
<listitem>
<para>Packages in nixpkgs can be marked as insecure through listed
vulnerabilities. See the <link

</itemizedlist>
<para>When upgrading from a previous release, please be aware of the
following incompatible changes:</para>
<itemizedlist>
<listitem>
<para>
Cross compilation has been rewritten. See the nixpkgs manual for
details. The most obvious breaking change is that derivations absent a
<literal>.nativeDrv</literal> or <literal>.crossDrv</literal> are now
cross by default, not native.
</para>
</listitem>
<listitem>
<para>
<literal>stdenv.overrides</literal> is now expected to take <literal>self</literal>
and <literal>super</literal> arguments. See <literal>lib.trivial.extends</literal>
for what those parameters represent.
</para>
</listitem>
<listitem>
<para>
<literal>ansible</literal> now defaults to ansible version 2 as version 1
has been removed due to a serious <link
xlink:href="https://www.computest.nl/advisories/CT-2017-0109_Ansible.txt">
vulnerability</link> unpatched by upstream.
</para>
</listitem>
<listitem>
<para>
<literal>gnome</literal> alias has been removed along with
<literal>gtk</literal>, <literal>gtkmm</literal> and several others.
Now you need to use versioned attributes, like <literal>gnome3</literal>.
</para>
</listitem>
<listitem>
<para>
The attribute name of the Radicale daemon has been changed from
<literal>pythonPackages.radicale</literal> to
<literal>radicale</literal>.
</para>
</listitem>
<listitem>
<para>
The <literal>stripHash</literal> bash function in <literal>stdenv</literal>
changed according to its documentation; it now outputs the stripped name to
<literal>stdout</literal> instead of putting it in the variable
<literal>strippedName</literal>.
</para>
</listitem>
<listitem>
<para>PHP now scans for extra configuration .ini files in /etc/php.d
instead of /etc. This prevents accidentally loading non-PHP .ini files
that may be in /etc.
</para>
</listitem>
<listitem>
<para>
Two lone top-level dict dbs moved into <literal>dictdDBs</literal>. This
affects: <literal>dictdWordnet</literal> which is now at
<literal>dictdDBs.wordnet</literal> and <literal>dictdWiktionary</literal>
which is now at <literal>dictdDBs.wiktionary</literal>
</para>
</listitem>
<listitem>
<para>
Parsoid service now uses YAML configuration format.
<literal>service.parsoid.interwikis</literal> is now called
<literal>service.parsoid.wikis</literal> and is a list of either API URLs
or attribute sets as specified in parsoid's documentation.
</para>
</listitem>
<listitem>
<para>
<literal>Ntpd</literal> was replaced by
<literal>systemd-timesyncd</literal> as the default service to synchronize
system time with a remote NTP server. The old behavior can be restored by
setting <literal>services.ntp.enable</literal> to <literal>true</literal>.
Upstream time servers for all NTP implementations are now configured using
<literal>networking.timeServers</literal>.
</para>
</listitem>
<listitem>
<para>
<literal>service.nylon</literal> is now declared using named instances.
As an example:
<programlisting>
services.nylon = {
enable = true;
acceptInterface = "br0";
bindInterface = "tun1";
port = 5912;
};
</programlisting>
should be replaced with:
<programlisting>
services.nylon.myvpn = {
enable = true;
acceptInterface = "br0";
bindInterface = "tun1";
port = 5912;
};
</programlisting>
this enables you to declare a SOCKS proxy for each uplink.
</para>
</listitem>
<listitem>
<para><literal>overridePackages</literal> function no longer exists.
It is replaced by <link
xlink:href="https://nixos.org/nixpkgs/manual/#sec-overlays-install">
overlays</link>. For example, the following code:
<programlisting>
let
pkgs = import &lt;nixpkgs&gt; {};
in
pkgs.overridePackages (self: super: ...)
</programlisting>
should be replaced by:
<programlisting>
let
pkgs = import &lt;nixpkgs&gt; {};
in
import pkgs.path { overlays = [(self: super: ...)] }
</programlisting>
</para>
</listitem>
<listitem>
<para>
Autoloading connection tracking helpers is now disabled by default.
This default was also changed in the Linux kernel and is considered
insecure if not configured properly in your firewall. If you need
connection tracking helpers (i.e. for active FTP) please enable
<literal>networking.firewall.autoLoadConntrackHelpers</literal> and
tune <literal>networking.firewall.connectionTrackingModules</literal>
to suit your needs.
</para>
</listitem>
<listitem>
<para>
<literal>local_recipient_maps</literal> is not set to empty value by
Postfix service. It's an insecure default as stated by Postfix
documentation. Those who want to retain this setting need to set it via
<literal>services.postfix.extraConfig</literal>.
</para>
</listitem>
<listitem>
<para>
Iputils no longer provide ping6 and traceroute6. The functionality of
these tools have been integrated into ping and traceroute respectively. To
enforce an address family the new flags <literal>-4</literal> and
<literal>-6</literal> have been added. One notable incompatibility is that
specifying an interface (for link-local IPv6 for instance) is no longer done
with the <literal>-I</literal> flag, but by encoding the interface into the
address (<literal>ping fe80::1%eth0</literal>).
</para>
</listitem>
<listitem>
<para>
The socket handling of the <literal>services.rmilter</literal> module
has been fixed and refactored. As rmilter doesn't support binding to
more than one socket, the options <literal>bindUnixSockets</literal>
and <literal>bindInetSockets</literal> have been replaced by
<literal>services.rmilter.bindSocket.*</literal>. The default is still
a unix socket in <literal>/run/rmilter/rmilter.sock</literal>. Refer to
the options documentation for more information.
</para>
</listitem>
<listitem>
<para>
The <literal>fetch*</literal> functions no longer support md5,
please use sha256 instead.
</para>
</listitem>
<listitem>
<para>
The dnscrypt-proxy module interface has been streamlined around the
<option>extraArgs</option> option. Where possible, legacy option
declarations are mapped to <option>extraArgs</option> but will emit
warnings. The <option>resolverList</option> has been outright
removed: to use an unlisted resolver, use the
<option>customResolver</option> option.
</para>
</listitem>
</itemizedlist>
<para>Other notable changes:</para>
<itemizedlist>
<listitem>
<para>Module type system have a new extensible option types feature that
allow to extend certain types, such as enum, through multiple option
declarations of the same option across multiple modules.
</para>
</listitem>
<listitem>
<para>
<literal>jre</literal> now defaults to GTK+ UI by default. This
improves visual consistency and makes Java follow system font style,
improving the situation on HighDPI displays. This has a cost of increased
closure size; for server and other headless workloads it's recommended to
use <literal>jre_headless</literal>.
</para>
</listitem>
<listitem>
<para>Python 2.6 interpreter and package set have been removed.</para>
</listitem>
<listitem>
<para>The Python 2.7 interpreter does not use modules anymore. Instead, all CPython interpreters now include the whole standard library except for `tkinter`, which is available in the Python package set.</para>
</listitem>
<listitem>
<para>
Python 2.7, 3.5 and 3.6 are now built deterministically and 3.4 mostly.
Minor modifications had to be made to the interpreters in order to generate
deterministic bytecode. This has security implications and is relevant for
those using Python in a <literal>nix-shell</literal>. See the Nixpkgs manual
for details.
</para>
</listitem>
<listitem>
<para>The Python package sets now use a fixed-point combinator and the sets are available as attributes of the interpreters.</para>
</listitem>
<listitem>
<para>The Python function `buildPythonPackage` has been improved and can be used to build from Setuptools source, Flit source, and precompiled Wheels.</para>
</listitem>
<listitem>
<para>
When adding new or updating current Python libraries, the expressions should be put
in separate files in <literal>pkgs/development/python-modules</literal> and
called from <literal>python-packages.nix</literal>.
</para>
</listitem>
<listitem>
<para>
The dnscrypt-proxy service supports synchronizing the list of public
resolvers without working DNS resolution. This fixes issues caused by the
resolver list becoming outdated. It also improves the viability of
DNSCrypt only configurations.
