reproducible builds</link>. For example, <literal>stdenv</literal> now sets
the environment variable
<envar
xlink:href="https://reproducible-builds.org/specs/source-date-epoch/">SOURCE_DATE_EPOCH</envar>
to a deterministic value, and Nix has
<link
xlink:href="http://nixos.org/nix/manual/#ssec-relnotes-1.11">gained
an option</link> to repeat a build a number of times to test determinism.
An ongoing project, the goal of exact reproducibility is to allow binaries
to be verified independently (e.g., a user might only trust binaries that
appear in three independent binary caches).

When upgrading from a previous release, please be aware of the following
incompatible changes:
</para>
<itemizedlist>
<listitem>
<para>
We no longer produce graphical ISO images and VirtualBox images for
<literal>i686-linux</literal>. A minimal ISO image is still provided.
</para>
</listitem>
<listitem>
<para>
Firefox and similar browsers are now <emphasis>wrapped by
default</emphasis>. The package and attribute names are plain
<literal>firefox</literal> or <literal>midori</literal>, etc.
Backward-compatibility attributes were set up, but note that
<command>nix-env -u</command> will <emphasis>not</emphasis> update your
current <literal>firefox-with-plugins</literal>; you have to uninstall it
and install <literal>firefox</literal> instead.
</para>
</listitem>
<listitem>
<para>
<command>wmiiSnap</command> has been replaced with
<command>wmii_hg</command>, but
<command>services.xserver.windowManager.wmii.enable</command> has been
updated respectively so this only affects you if you have explicitly
installed <command>wmiiSnap</command>.
</para>
</listitem>
<listitem>
<para>
<literal>jobs</literal> NixOS option has been removed. It served as
compatibility layer between Upstart jobs and SystemD services. All services
have been rewritten to use <literal>systemd.services</literal>
</para>
</listitem>
<listitem>
<para>
<command>wmiimenu</command> is removed, as it has been removed by the
developers upstream. Use <command>wimenu</command> from the
<command>wmii-hg</command> package.
</para>
</listitem>
<listitem>
<para>
Gitit is no longer automatically added to the module list in NixOS and as
such there will not be any manual entries for it. You will need to add an
import statement to your NixOS configuration in order to use it, e.g.
<programlisting><![CDATA[
{
imports = [ <nixpkgs/nixos/modules/services/misc/gitit.nix> ];
}
]]></programlisting>
will include the Gitit service configuration options.
</para>
</listitem>
<listitem>
<para>
<command>nginx</command> does not accept flags for enabling and disabling
modules anymore. Instead it accepts <literal>modules</literal> argument,
which is a list of modules to be built in. All modules now reside in
<literal>nginxModules</literal> set. Example configuration:
<programlisting><![CDATA[
nginx.override {
modules = [ nginxModules.rtmp nginxModules.dav nginxModules.moreheaders ];
}
]]></programlisting>
</para>
</listitem>
<listitem>
<para>
<command>s3sync</command> is removed, as it hasn't been developed by
upstream for 4 years and only runs with ruby 1.8. For an actively-developer
alternative look at <command>tarsnap</command> and others.
</para>
</listitem>
<listitem>
<para>
<command>ruby_1_8</command> has been removed as it's not supported from
upstream anymore and probably contains security issues.
</para>
</listitem>
<listitem>
<para>
<literal>tidy-html5</literal> package is removed. Upstream only provided
<literal>(lib)tidy5</literal> during development, and now they went back to
<literal>(lib)tidy</literal> to work as a drop-in replacement of the
original package that has been unmaintained for years. You can (still) use
the <literal>html-tidy</literal> package, which got updated to a stable
release from this new upstream.
</para>
</listitem>
<listitem>
<para>
<literal>extraDeviceOptions</literal> argument is removed from
<literal>bumblebee</literal> package. Instead there are now two separate
arguments: <literal>extraNvidiaDeviceOptions</literal> and
<literal>extraNouveauDeviceOptions</literal> for setting extra X11 options
for nvidia and nouveau drivers, respectively.
</para>
</listitem>
<listitem>
<para>
The <literal>Ctrl+Alt+Backspace</literal> key combination no longer kills
the X server by default. There's a new option
<option>services.xserver.enableCtrlAltBackspace</option> allowing to enable
the combination again.
</para>
</listitem>
<listitem>
<para>
<literal>emacsPackagesNg</literal> now contains all packages from the ELPA,
MELPA, and MELPA Stable repositories.
</para>
</listitem>
<listitem>
<para>
Data directory for Postfix MTA server is moved from
<filename>/var/postfix</filename> to <filename>/var/lib/postfix</filename>.
Old configurations are migrated automatically.
<literal>service.postfix</literal> module has also received many
improvements, such as correct directories' access rights, new
<literal>aliasFiles</literal> and <literal>mapFiles</literal> options and
more.
</para>
</listitem>
<listitem>
<para>
Filesystem options should now be configured as a list of strings, not a
comma-separated string. The old style will continue to work, but print a
warning, until the 16.09 release. An example of the new style:
<programlisting>
fileSystems."/example" = {
device = "/dev/sdc";
fsType = "btrfs";
options = [ "noatime" "compress=lzo" "space_cache" "autodefrag" ];
};
</programlisting>
</para>
</listitem>
<listitem>
<para>
CUPS, installed by <literal>services.printing</literal> module, now has its
data directory in <filename>/var/lib/cups</filename>. Old configurations
from <filename>/etc/cups</filename> are moved there automatically, but
there might be problems. Also configuration options
<literal>services.printing.cupsdConf</literal> and
<literal>services.printing.cupsdFilesConf</literal> were removed because
they had been allowing one to override configuration variables required for
CUPS to work at all on NixOS. For most use cases,
<literal>services.printing.extraConf</literal> and new option
<literal>services.printing.extraFilesConf</literal> should be enough; if
you encounter a situation when they are not, please file a bug.
</para>
<para>
There are also Gutenprint improvements; in particular, a new option
<literal>services.printing.gutenprint</literal> is added to enable
automatic updating of Gutenprint PPMs; it's greatly recommended to enable
it instead of adding <literal>gutenprint</literal> to the
<literal>drivers</literal> list.
</para>
</listitem>
<listitem>
<para>
<literal>services.xserver.vaapiDrivers</literal> has been removed. Use
<literal>hardware.opengl.extraPackages{,32}</literal> instead. You can also
specify VDPAU drivers there.
</para>
</listitem>
<listitem>
<para>
<literal>programs.ibus</literal> moved to
<literal>i18n.inputMethod.ibus</literal>. The option
<literal>programs.ibus.plugins</literal> changed to
<literal>i18n.inputMethod.ibus.engines</literal> and the option to enable
ibus changed from <literal>programs.ibus.enable</literal> to
<literal>i18n.inputMethod.enabled</literal>.
<literal>i18n.inputMethod.enabled</literal> should be set to the used input
method name, <literal>"ibus"</literal> for ibus. An example of the new
style:
<programlisting>
i18n.inputMethod.enabled = "ibus";
i18n.inputMethod.ibus.engines = with pkgs.ibus-engines; [ anthy mozc ];
</programlisting>
That is equivalent to the old version:
<programlisting>
programs.ibus.enable = true;
programs.ibus.plugins = with pkgs; [ ibus-anthy mozc ];
</programlisting>
</para>
</listitem>
<listitem>
<para>
<literal>services.udev.extraRules</literal> option now writes rules to
<filename>99-local.rules</filename> instead of
<filename>10-local.rules</filename>. This makes all the user rules apply
after others, so their results wouldn't be overriden by anything else.
</para>
</listitem>
<listitem>
<para>
Large parts of the <literal>services.gitlab</literal> module has been been
rewritten. There are new configuration options available. The
<literal>stateDir</literal> option was renamned to
<literal>statePath</literal> and the <literal>satellitesDir</literal>
option was removed. Please review the currently available options.
</para>
</listitem>
<listitem>
<para>
The option <option>services.nsd.zones.&lt;name&gt;.data</option> no longer
interpret the dollar sign ($) as a shell variable, as such it should not be
escaped anymore. Thus the following zone data:
</para>
<programlisting>
\$ORIGIN example.com.
\$TTL 1800
@ IN SOA ns1.vpn.nbp.name. admin.example.com. (
</programlisting>
<para>
Should modified to look like the actual file expected by nsd:
</para>
<programlisting>
$ORIGIN example.com.
$TTL 1800
@ IN SOA ns1.vpn.nbp.name. admin.example.com. (
</programlisting>
</listitem>
<listitem>
<para>
<literal>service.syncthing.dataDir</literal> options now has to point to
exact folder where syncthing is writing to. Example configuration should
look something like:
</para>
<programlisting>
services.syncthing = {
enable = true;
dataDir = "/home/somebody/.syncthing";
user = "somebody";
};
</programlisting>
</listitem>
<listitem>
<para>
<literal>networking.firewall.allowPing</literal> is now enabled by default.
Users are encouraged to configure an appropriate rate limit for their
machines using the Kernel interface at
<filename>/proc/sys/net/ipv4/icmp_ratelimit</filename> and
<filename>/proc/sys/net/ipv6/icmp/ratelimit</filename> or using the
firewall itself, i.e. by setting the NixOS option
<literal>networking.firewall.pingLimit</literal>.
</para>
</listitem>
<listitem>
<para>
Systems with some broadcom cards used to result into a generated config
that is no longer accepted. If you get errors like
<screen>error: path /nix/store/*-broadcom-sta-* does not exist and cannot be created</screen>
you should either re-run <command>nixos-generate-config</command> or
manually replace
<literal>"${config.boot.kernelPackages.broadcom_sta}"</literal> by
<literal>config.boot.kernelPackages.broadcom_sta</literal> in your
<filename>/etc/nixos/hardware-configuration.nix</filename>. More discussion
is on <link xlink:href="https://github.com/NixOS/nixpkgs/pull/12595"> the
github issue</link>.
</para>
</listitem>
<listitem>
<para>
The <literal>services.xserver.startGnuPGAgent</literal> option has been
removed. GnuPG 2.1.x changed the way the gpg-agent works, and that new
approach no longer requires (or even supports) the "start everything as a
child of the agent" scheme we've implemented in NixOS for older versions.
To configure the gpg-agent for your X session, add the following code to
<filename>~/.bashrc</filename> or some file thats sourced when your
shell is started:
<programlisting>
GPG_TTY=$(tty)
export GPG_TTY
</programlisting>
If you want to use gpg-agent for SSH, too, add the following to your
session initialization (e.g.
<literal>displayManager.sessionCommands</literal>)
<programlisting>
gpg-connect-agent /bye
unset SSH_AGENT_PID
export SSH_AUTH_SOCK="''${HOME}/.gnupg/S.gpg-agent.ssh"
</programlisting>
and make sure that
<programlisting>
enable-ssh-support
</programlisting>
is included in your <filename>~/.gnupg/gpg-agent.conf</filename>. You will
need to use <command>ssh-add</command> to re-add your ssh keys. If gpgs
automatic transformation of the private keys to the new format fails, you
will need to re-import your private keyring as well:
<programlisting>
gpg --import ~/.gnupg/secring.gpg
</programlisting>
The <command>gpg-agent(1)</command> man page has more details about this
subject, i.e. in the "EXAMPLES" section.
</para>
</listitem>
</itemizedlist>
<para>
Other notable improvements:
<itemizedlist>
<!--
<listitem>
<para>The <command>command-not-found</command> hook was extended.
Apart from <literal>$NIX_AUTO_INSTALL</literal> variable,
it newly also checks for <literal>$NIX_AUTO_RUN</literal>
which causes it to directly run the missing commands via
<command>nix-shell</command> (without installing anything).</para>
</listitem>
-->
<listitem>
<para>
<literal>ejabberd</literal> module is brought back and now works on NixOS.
</para>
</listitem>
<listitem>
<para>
Input method support was improved. New NixOS modules (fcitx, nabi and
uim), fcitx engines (chewing, hangul, m17n, mozc and table-other) and ibus
engines (hangul and m17n) have been added.
