In addition to numerous new and upgraded packages, this release has
the following highlights:

Improved support for ensuring
<link xlink:href="https://reproducible-builds.org/">bitwise
reproducible builds</link>. For example,
<literal>stdenv</literal> now sets the environment variable
<literal>SOURCE_DATE_EPOCH</literal> to a deterministic value,
and Nix has
<link xlink:href="https://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
<literal>nix-env -u</literal> 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>
<literal>wmiiSnap</literal> has been replaced with
<literal>wmii_hg</literal>, but
<literal>services.xserver.windowManager.wmii.enable</literal>
has been updated respectively so this only affects you if you
have explicitly installed <literal>wmiiSnap</literal>.
</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>
<literal>wmiimenu</literal> is removed, as it has been removed
by the developers upstream. Use <literal>wimenu</literal> from
the <literal>wmii-hg</literal> 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.
</para>
<programlisting language="bash">
{
imports = [ &lt;nixpkgs/nixos/modules/services/misc/gitit.nix&gt; ];
}
</programlisting>
<para>
will include the Gitit service configuration options.
</para>
</listitem>
<listitem>
<para>
<literal>nginx</literal> 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:
</para>
<programlisting language="bash">
nginx.override {
modules = [ nginxModules.rtmp nginxModules.dav nginxModules.moreheaders ];
}
</programlisting>
</listitem>
<listitem>
<para>
<literal>s3sync</literal> 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
<literal>tarsnap</literal> and others.
</para>
</listitem>
<listitem>
<para>
<literal>ruby_1_8</literal> 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
<literal>services.xserver.enableCtrlAltBackspace</literal>
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
<literal>/var/postfix</literal> to
<literal>/var/lib/postfix</literal>. 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:
</para>
<programlisting language="bash">
{
fileSystems.&quot;/example&quot; = {
device = &quot;/dev/sdc&quot;;
fsType = &quot;btrfs&quot;;
options = [ &quot;noatime&quot; &quot;compress=lzo&quot; &quot;space_cache&quot; &quot;autodefrag&quot; ];
};
}
</programlisting>
</listitem>
<listitem>
<para>
CUPS, installed by <literal>services.printing</literal> module,
now has its data directory in <literal>/var/lib/cups</literal>.
Old configurations from <literal>/etc/cups</literal> 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>&quot;ibus&quot;</literal> for
ibus. An example of the new style:
</para>
<programlisting language="bash">
{
i18n.inputMethod.enabled = &quot;ibus&quot;;
i18n.inputMethod.ibus.engines = with pkgs.ibus-engines; [ anthy mozc ];
}
</programlisting>
<para>
That is equivalent to the old version:
</para>
<programlisting language="bash">
{
programs.ibus.enable = true;
programs.ibus.plugins = with pkgs; [ ibus-anthy mozc ];
}
</programlisting>
</listitem>
<listitem>
<para>
<literal>services.udev.extraRules</literal> option now writes
rules to <literal>99-local.rules</literal> instead of
<literal>10-local.rules</literal>. 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
<literal>services.nsd.zones.&lt;name&gt;.data</literal> 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.
$TTL 1800
@ IN SOA ns1.vpn.nbp.name. admin.example.com. (
</programlisting>
</listitem>
<listitem>
<para>
<literal>service.syncthing.dataDir</literal> options now has to
point to exact folder where syncthing is writing to. Example
configuration should look something like:
</para>
<programlisting language="bash">
{
services.syncthing = {
enable = true;
dataDir = &quot;/home/somebody/.syncthing&quot;;
user = &quot;somebody&quot;;
};
}
</programlisting>
</listitem>
<listitem>
<para>
<literal>networking.firewall.allowPing</literal> is now enabled
by default. Users are encouraged to configure an appropriate
rate limit for their machines using the Kernel interface at
<literal>/proc/sys/net/ipv4/icmp_ratelimit</literal> and
<literal>/proc/sys/net/ipv6/icmp/ratelimit</literal> or using
the firewall itself, i.e. by setting the NixOS option
<literal>networking.firewall.pingLimit</literal>.
</para>
</listitem>
<listitem>
<para>
Systems with some broadcom cards used to result into a generated
config that is no longer accepted. If you get errors like
</para>
<programlisting>
error: path ‘/nix/store/*-broadcom-sta-*’ does not exist and cannot be created
</programlisting>
<para>
you should either re-run
<literal>nixos-generate-config</literal> or manually replace
<literal>&quot;${config.boot.kernelPackages.broadcom_sta}&quot;</literal>
by <literal>config.boot.kernelPackages.broadcom_sta</literal> in
your <literal>/etc/nixos/hardware-configuration.nix</literal>.
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 &quot;start everything as a child of the
agent&quot; scheme we've implemented in NixOS for older
versions. To configure the gpg-agent for your X session, add the
following code to <literal>~/.bashrc</literal> or some file
that’s sourced when your shell is started:
</para>
<programlisting>
GPG_TTY=$(tty)
export GPG_TTY
</programlisting>
<para>
If you want to use gpg-agent for SSH, too, add the following to
your session initialization (e.g.
<literal>displayManager.sessionCommands</literal>)
</para>
<programlisting>
gpg-connect-agent /bye
unset SSH_AGENT_PID
export SSH_AUTH_SOCK=&quot;''${HOME}/.gnupg/S.gpg-agent.ssh&quot;
</programlisting>
<para>
and make sure that
</para>
<programlisting>
enable-ssh-support
</programlisting>
<para>
is included in your <literal>~/.gnupg/gpg-agent.conf</literal>.
You will need to use <literal>ssh-add</literal> to re-add your
ssh keys. If gpg’s automatic transformation of the private keys
to the new format fails, you will need to re-import your private
keyring as well:
</para>
<programlisting>
gpg --import ~/.gnupg/secring.gpg
</programlisting>
<para>
The <literal>gpg-agent(1)</literal> man page has more details
about this subject, i.e. in the &quot;EXAMPLES&quot; section.
</para>
</listitem>
</itemizedlist>
<para>
Other notable improvements:
</para>

<listitem>
<para>
<literal>ejabberd</literal> module is brought back and now works
on NixOS.
</para>
</listitem>
<listitem>

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.
