<para>In addition to numerous new and upgraded packages, this release
|
|
has the following highlights:</para>
|
|
|
|
<itemizedlist>
|
|
|
|
<listitem>
|
|
<para>You can now pin a specific version of NixOS in your <filename>configuration.nix</filename>
|
|
by setting:
|
|
|
|
<programlisting>
|
|
nixos.path = ./nixpkgs-unstable-2015-12-06/nixos;
|
|
</programlisting>
|
|
|
|
This will make NixOS re-evaluate your configuration with the modules of
|
|
the specified NixOS version at the given path. For more details, see
|

<para>The following new services were added since the last release:

<para>When upgrading from a previous release, please be aware of the
|
|
following incompatible changes:</para>
|
|
|
|
<itemizedlist>
|
|
<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><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 = [ <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>
|
|
<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.
