Release 18.03 (“Impala”, 2018/03/??)HighlightsIn addition to numerous new and upgraded packages, this release
has the following highlights:
MariaDB 10.2, updated from 10.1, is now the default MySQL implementation. While upgrading a few changes
have been made to the infrastructure involved:
libmysql has been deprecated, please use mysql.connector-c
instead, a compatibility passthru has been added to the MySQL packages.
The mysql57 package has a new static output containing
the static libraries including libmysqld.aPHP now defaults to PHP 7.2New ServicesThe following new services were added since the last release:Backward IncompatibilitiesWhen upgrading from a previous release, please be aware of the
following incompatible changes:
Dollar signs in options under are
passed verbatim to Postfix, which will interpret them as the beginning of
a parameter expression. This was already true for string-valued options
in the previous release, but not for list-valued options. If you need to
pass literal dollar signs through Postfix, double them.
The postage package (for web-based PostgreSQL
administration) has been renamed to pgmanage. The
corresponding module has also been renamed. To migrate please rename all
options to
.
Package attributes starting with a digit have been prefixed with an
underscore sign. This is to avoid quoting in the configuration and
other issues with command-line tools like nix-env.
The change affects the following packages:
2048-in-terminal → _2048-in-terminal90secondportraits → _90secondportraits2bwm → _2bwm389-ds-base → _389-ds-base
The OpenSSH service no longer enables support for DSA keys by default,
which could cause a system lock out. Update your keys or, unfavorably,
re-enable DSA support manually.
DSA support was
deprecated in OpenSSH 7.0,
due to it being too weak. To re-enable support, add
PubkeyAcceptedKeyTypes +ssh-dss to the end of your
.
After updating the keys to be stronger, anyone still on a pre-17.03
version is safe to jump to 17.03, as vetted
here.
cc-wrapper has been split in two; there is now also a bintools-wrapper.
The most commonly used files in nix-support are now split between the two wrappers.
Some commonly used ones, like nix-support/dynamic-linker, are duplicated for backwards compatability, even though they rightly belong only in bintools-wrapper.
Other more obscure ones are just moved.
The propagation logic has been changed.
The new logic, along with new types of dependencies that go with, is thoroughly documented in the "Specifying dependencies" section of the "Standard Environment" chapter of the nixpkgs manual.
The old logic isn't but is easy to describe: dependencies were propagated as the same type of dependency no matter what.
In practice, that means that many propagatedNativeBuildInputs should instead be propagatedBuildInputs.
Thankfully, that was and is the least used type of dependency.
Also, it means that some propagatedBuildInputs should instead be depsTargetTargetPropagated.
Other types dependencies should be unaffected.
lib.addPassthru drv passthru is removed. Use lib.extendDerivation true passthru drv instead. TODO: actually remove it before branching 18.03 off.
The memcached service no longer accept dynamic socket
paths via . Unix sockets can be
still enabled by and
will be accessible at /run/memcached/memcached.sock.
The hardware.amdHybridGraphics.disable option was removed for lack of a maintainer. If you still need this module, you may wish to include a copy of it from an older version of nixos in your imports.
The merging of config options for services.postfix.config
was buggy. Previously, if other options in the Postfix module like
services.postfix.useSrs were set and the user set config
options that were also set by such options, the resulting config wouldn't
include all options that were needed. They are now merged correctly. If
config options need to be overridden, lib.mkForce or
lib.mkOverride can be used.
The following changes apply if the stateVersion is changed to 18.03 or higher.
For stateVersion = "17.09" or lower the old behavior is preserved.
matrix-synapse uses postgresql by default instead of sqlite.
Migration instructions can be found here .
The jid package has been removed, due to maintenance
overhead of a go package having non-versioned dependencies.
When using (enabled by default in GNOME),
it now handles all input devices, not just touchpads. As a result, you might need to
re-evaluate any custom Xorg configuration. In particular,
Option "XkbRules" "base" may result in broken keyboard layout.
Other Notable Changes
ZNC option now defaults to
true. That means that old configuration is not
overwritten by default when update to the znc options are made.
The option
has been added for wireless networks with WPA-Enterprise authentication.
There is also a new option to directly
configure wpa_supplicant and
to connect to hidden networks.
The option is now none by default.
An assertion failure is thrown if WM's and DM's default are none.
To explicitly run a plain X session without and DM or WM, the newly introduced option
must be set to true.
The option is now 127.0.0.1 by default.
Previously the default behaviour was to listen on all interfaces.
services.btrfs.autoScrub has been added, to
periodically check btrfs filesystems for data corruption.
If there's a correct copy available, it will automatically repair
corrupted blocks.
displayManager.lightdm.greeters.gtk.clock-format.
has been added, the clock format string (as expected by
strftime, e.g. %H:%M) to use with the lightdm
gtk greeter panel.
If set to null the default clock format is used.
displayManager.lightdm.greeters.gtk.indicators
has been added, a list of allowed indicator modules to use with
the lightdm gtk greeter panel.
Built-in indicators include ~a11y,
~language, ~session,
~power, ~clock,
~host, ~spacer. Unity
indicators can be represented by short name
(e.g. sound, power),
service file name, or absolute path.
If set to null the default indicators are
used.
In order to have the previous default configuration add
services.xserver.displayManager.lightdm.greeters.gtk.indicators = [
"~host" "~spacer"
"~clock" "~spacer"
"~session"
"~language"
"~a11y"
"~power"
];
to your configuration.nix.
The NixOS test driver supports user services declared by systemd.user.services.
The methods waitForUnit, getUnitInfo, startJob
and stopJob provide an optional $user argument for that purpose.
