In addition to numerous new and upgraded packages, this release has the following highlights: PXE "netboot" media has landed in . See for documentation. Xorg-server-1.18.*. If you choose "ati_unfree" driver, 1.17.* is still used due to ABI incompatibility. The following new services were added since the last release: (this will get automatically generated at release time) When upgrading from a previous release, please be aware of the following incompatible changes: Shell aliases for systemd sub-commands were dropped: start, stop, restart, status. Redis now binds to 127.0.0.1 only instead of listening to all network interfaces. This is the default behavior of Redis 3.2 Gitlab's maintainence script gitlab-runner was removed and split up into the more clearer gitlab-run and gitlab-rake scripts because gitlab-runner is a component of Gitlab CI. services.xserver.libinput.accelProfile default changed from flat to adaptive, as per official documentation. fonts.fontconfig.ultimate.rendering was removed because our presets were obsolete for some time. New presets are hardcoded into freetype; one selects a preset via fonts.fontconfig.ultimate.preset. You can customize those presets via ordinary environment variables, using environment.variables. Other notable improvements: Revamped grsecurity/PaX support. There is now only a single general-purpose distribution kernel and the configuration interface has been streamlined. Desktop users should be able to simply set security.grsecurity.enable = true to get a reasonably secure system without having to sacrifice too much functionality. See for documentation
