In addition to numerous + new and upgraded packages and modules, this release has the following + highlights: + <itemizedlist> + <listitem> + <para> + Installation on UEFI systems is now supported. See + <xref linkend="sec-installation"/> for details. + </para> + </listitem> + <listitem> + <para> + Systemd has been updated to version 212, which has + <link xlink:href="http://cgit.freedesktop.org/systemd/systemd/plain/NEWS?id=v212">numerous + improvements</link>. NixOS now automatically starts systemd user instances + when you log in. You can define global user units through the + <option>systemd.unit.*</option> options. + </para> + </listitem> + <listitem> + <para> + NixOS is now based on Glibc 2.19 and GCC 4.8. + </para> + </listitem> + <listitem> + <para> + The default Linux kernel has been updated to 3.12. + </para> + </listitem> + <listitem> + <para> + KDE has been updated to 4.12. + </para> + </listitem> + <listitem> + <para> + GNOME 3.10 experimental support has been added. + </para> + </listitem> + <listitem> + <para> + Nix has been updated to 1.7 + (<link + xlink:href="https://nixos.org/nix/manual/#ssec-relnotes-1.7">details</link>). + </para> + </listitem> + <listitem> + <para> + NixOS now supports fully declarative management of users and groups. If + you set <option>users.mutableUsers</option> to <literal>false</literal>, + then the contents of <filename>/etc/passwd</filename> and + <filename>/etc/group</filename> will be + <link + xlink:href="https://www.usenix.org/legacy/event/lisa02/tech/full_papers/traugott/traugott_html/">congruent</link> + to your NixOS configuration. For instance, if you remove a user from + <option>users.extraUsers</option> and run + <command>nixos-rebuild</command>, the user account will cease to exist. + Also, imperative commands for managing users and groups, such as + <command>useradd</command>, are no longer available. If + <option>users.mutableUsers</option> is <literal>true</literal> (the + default), then behaviour is unchanged from NixOS 13.10. + </para> + </listitem> + <listitem> + <para> + NixOS now has basic container support, meaning you can easily run a NixOS + instance as a container in a NixOS host system. These containers are + suitable for testing and experimentation but not production use, since + they’re not fully isolated from the host. See + <xref linkend="ch-containers"/> for details. + </para> + </listitem> + <listitem> + <para> + Systemd units provided by packages can now be overridden from the NixOS + configuration. For instance, if a package <literal>foo</literal> provides + systemd units, you can say: +<programlisting> +systemd.packages = [ pkgs.foo ]; +</programlisting> + to enable those units. You can then set or override unit options in the + usual way, e.g. +<programlisting> +systemd.services.foo.wantedBy = [ "multi-user.target" ]; +systemd.services.foo.serviceConfig.MemoryLimit = "512M"; +</programlisting> + </para> + </listitem> + </itemizedlist> + </para> + + <para> + When upgrading from a previous release, please be aware of the following + incompatible changes: + <itemizedlist> + <listitem> + <para> + Nixpkgs no longer exposes unfree packages by default. If your NixOS + configuration requires unfree packages from Nixpkgs, you need to enable + support for them explicitly by setting: +<programlisting> +nixpkgs.config.allowUnfree = true; +</programlisting> + Otherwise, you get an error message such as: +<screen> +error: package ‘nvidia-x11-331.49-3.12.17’ in ‘…/nvidia-x11/default.nix:56’ + has an unfree license, refusing to evaluate +</screen> + </para> + </listitem> + <listitem> + <para> + The Adobe Flash player is no longer enabled by default in the Firefox and + Chromium wrappers. To enable it, you must set: +<programlisting> +nixpkgs.config.allowUnfree = true; +nixpkgs.config.firefox.enableAdobeFlash = true; # for Firefox +nixpkgs.config.chromium.enableAdobeFlash = true; # for Chromium +</programlisting> + </para> + </listitem> + <listitem> + <para> + The firewall is now enabled by default. If you don’t want this, you need + to disable it explicitly: +<programlisting> +networking.firewall.enable = false; +</programlisting> + </para> + </listitem> + <listitem> + <para> + The option <option>boot.loader.grub.memtest86</option> has been renamed to + <option>boot.loader.grub.memtest86.enable</option>. + </para> + </listitem> + <listitem> + <para> + The <literal>mysql55</literal> service has been merged into the + <literal>mysql</literal> service, which no longer sets a default for the + option <option>services.mysql.package</option>. + </para> + </listitem> + <listitem> + <para> + Package variants are now differentiated by suffixing the name, rather than + the version. For instance, <filename>sqlite-3.8.4.3-interactive</filename> + is now called <filename>sqlite-interactive-3.8.4.3</filename>. This + ensures that <literal>nix-env -i sqlite</literal> is unambiguous, and that + <literal>nix-env -u</literal> won’t “upgrade” + <literal>sqlite</literal> to <literal>sqlite-interactive</literal> or vice + versa. Notably, this change affects the Firefox wrapper (which provides + plugins), as it is now called <literal>firefox-wrapper</literal>. So when + using <command>nix-env</command>, you should do <literal>nix-env -e + firefox; nix-env -i firefox-wrapper</literal> if you want to keep using + the wrapper. This change does not affect declarative package management, + since attribute names like <literal>pkgs.firefoxWrapper</literal> were + already unambiguous. + </para> + </listitem> + <listitem> + <para> + The symlink <filename>/etc/ca-bundle.crt</filename> is gone. Programs + should instead use the environment variable + <envar>OPENSSL_X509_CERT_FILE</envar> (which points to + <filename>/etc/ssl/certs/ca-bundle.crt</filename>). + </para> + </listitem> + </itemizedlist> + </para> +</section> |
