Release 14.12 ("Caterpillar", 2014/12/30)

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

• Systemd has been updated to version 217, which has numerous improvements.

• Nix has been updated to 1.8.

• NixOS is now based on Glibc 2.20.

• KDE has been updated to 4.14.

• The default Linux kernel has been updated to 3.14.

• If users.mutableUsers is enabled (the default), changes made to the declaration of a user or group will be correctly realised when running nixos-rebuild. For instance, removing a user specification from configuration.nix will cause the actual user account to be deleted. If users.mutableUsers is disabled, it is no longer necessary to specify UIDs or GIDs; if omitted, they are allocated dynamically.

When upgrading from a previous release, please be aware of the following incompatible changes:

• The default version of Apache httpd is now 2.4. If you use the extraConfig option to pass literal Apache configuration text, you may need to update it --- see Apache's documentation for details. If you wish to continue to use httpd 2.2, add the following line to your NixOS configuration:

  {
    services.httpd.package = pkgs.apacheHttpd_2_2;
  }
  

• PHP 5.3 has been removed because it is no longer supported by the PHP project. A migration guide is available.

• The host side of a container virtual Ethernet pair is now called ve-container-name rather than c-container-name.

• GNOME 3.10 support has been dropped. The default GNOME version is now 3.12.

• VirtualBox has been upgraded to 4.3.20 release. Users may be required to run rm -rf /tmp/.vbox*. The line imports = [ <nixpkgs/nixos/modules/programs/virtualbox.nix> ] is no longer necessary, use services.virtualboxHost.enable = true instead.

  Also, hardening mode is now enabled by default, which means that unless you want to use USB support, you no longer need to be a member of the vboxusers group.

• Chromium has been updated to 39.0.2171.65. enablePepperPDF is now enabled by default. chromium*Wrapper packages no longer exist, because upstream removed NSAPI support. chromium-stable has been renamed to chromium.

• Python packaging documentation is now part of nixpkgs manual. To override the python packages available to a custom python you now use pkgs.pythonFull.buildEnv.override instead of pkgs.pythonFull.override.

• boot.resumeDevice = "8:6" is no longer supported. Most users will want to leave it undefined, which takes the swap partitions automatically. There is an evaluation assertion to ensure that the string starts with a slash.

• The system-wide default timezone for NixOS installations changed from CET to UTC. To choose a different timezone for your system, configure time.timeZone in configuration.nix. A fairly complete list of possible values for that setting is available at https://en.wikipedia.org/wiki/List_of_tz_database_time_zones.

• GNU screen has been updated to 4.2.1, which breaks the ability to connect to sessions created by older versions of screen.

• The Intel GPU driver was updated to the 3.x prerelease version (used by most distributions) and supports DRI3 now.
