Release 17.03 (“Gorilla”, 2017/03/31)Highlights
In addition to numerous new and upgraded packages, this release has the
following highlights:
Nixpkgs is now extensible through overlays. See the
Nixpkgs
manual for more information.
This release is based on Glibc 2.25, GCC 5.4.0 and systemd 232. The
default Linux kernel is 4.9 and Nix is at 1.11.8.
The default desktop environment now is KDE's Plasma 5. KDE 4 has been
removed
The setuid wrapper functionality now supports setting capabilities.
X.org server uses branch 1.19. Due to ABI incompatibilities,
ati_unfree keeps forcing 1.17 and
amdgpu-pro starts forcing 1.18.
Cross compilation has been rewritten. See the nixpkgs manual for details.
The most obvious breaking change is that in derivations there is no
.nativeDrv nor .crossDrv are now
cross by default, not native.
The overridePackages function has been rewritten to be
replaced by
overlays
Packages in nixpkgs can be marked as insecure through listed
vulnerabilities. See the
Nixpkgs
manual for more information.
PHP now defaults to PHP 7.1

The following new services were added since the last release:

When upgrading from a previous release, please be aware of the following
incompatible changes:
Derivations have no .nativeDrv nor
.crossDrv and are now cross by default, not native.
stdenv.overrides is now expected to take
self and super arguments. See
lib.trivial.extends for what those parameters
represent.
ansible now defaults to ansible version 2 as version 1
has been removed due to a serious
vulnerability unpatched by upstream.
gnome alias has been removed along with
gtk, gtkmm and several others. Now
you need to use versioned attributes, like gnome3.
The attribute name of the Radicale daemon has been changed from
pythonPackages.radicale to radicale.
The stripHash bash function in
stdenv changed according to its documentation; it now
outputs the stripped name to stdout instead of putting
it in the variable strippedName.
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.
Two lone top-level dict dbs moved into dictdDBs. This
affects: dictdWordnet which is now at
dictdDBs.wordnet and dictdWiktionary
which is now at dictdDBs.wiktionary
Parsoid service now uses YAML configuration format.
service.parsoid.interwikis is now called
service.parsoid.wikis and is a list of either API URLs
or attribute sets as specified in parsoid's documentation.
Ntpd was replaced by
systemd-timesyncd as the default service to synchronize
system time with a remote NTP server. The old behavior can be restored by
setting services.ntp.enable to true.
Upstream time servers for all NTP implementations are now configured using
networking.timeServers.
service.nylon is now declared using named instances. As
an example:
services.nylon = {
enable = true;
acceptInterface = "br0";
bindInterface = "tun1";
port = 5912;
};
should be replaced with:
services.nylon.myvpn = {
enable = true;
acceptInterface = "br0";
bindInterface = "tun1";
port = 5912;
};
this enables you to declare a SOCKS proxy for each uplink.
overridePackages function no longer exists. It is
replaced by
overlays. For example, the following code:
let
pkgs = import <nixpkgs> {};
in
pkgs.overridePackages (self: super: ...)
should be replaced by:
let
pkgs = import <nixpkgs> {};
in
import pkgs.path { overlays = [(self: super: ...)]; }
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
networking.firewall.autoLoadConntrackHelpers and tune
networking.firewall.connectionTrackingModules to suit
your needs.
local_recipient_maps 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
services.postfix.extraConfig.
Iputils no longer provide ping6 and traceroute6. The functionality of
these tools has been integrated into ping and traceroute respectively. To
enforce an address family the new flags -4 and
-6 have been added. One notable incompatibility is that
specifying an interface (for link-local IPv6 for instance) is no longer
done with the -I flag, but by encoding the interface
into the address (ping fe80::1%eth0).
The socket handling of the services.rmilter module has
been fixed and refactored. As rmilter doesn't support binding to more than
one socket, the options bindUnixSockets and
bindInetSockets have been replaced by
services.rmilter.bindSocket.*. The default is still a
unix socket in /run/rmilter/rmilter.sock. Refer to the
options documentation for more information.
The fetch* functions no longer support md5, please use
sha256 instead.
The dnscrypt-proxy module interface has been streamlined around the
option. Where possible, legacy option
declarations are mapped to but will emit
warnings. The has been outright removed: to
use an unlisted resolver, use the option.
torbrowser now stores local state under
~/.local/share/tor-browser by default. Any browser
profile data from the old location, ~/.torbrowser4,
must be migrated manually.
The ihaskell, monetdb, offlineimap and sitecopy services have been
removed.
Other Notable Changes
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.
jre 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
jre_headless.
Python 2.6 interpreter and package set have been removed.
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.
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 nix-shell. See the
Nixpkgs manual for details.
The Python package sets now use a fixed-point combinator and the sets are
available as attributes of the interpreters.
The Python function buildPythonPackage has been
improved and can be used to build from Setuptools source, Flit source, and
precompiled Wheels.
When adding new or updating current Python libraries, the expressions
should be put in separate files in
pkgs/development/python-modules and called from
python-packages.nix.
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.
Containers using bridged networking no longer lose their connection after
changes to the host networking.
ZFS supports pool auto scrubbing.
The bind DNS utilities (e.g. dig) have been split into their own output
and are now also available in pkgs.dnsutils and it is
no longer necessary to pull in all of bind to use them.
Per-user configuration was moved from ~/.nixpkgs to
~/.config/nixpkgs. The former is still valid for
config.nix for backwards compatibility.
