This makes it easier to do - declarative package management similar to NixOS’s - <option>environment.systemPackages</option>. For instance, if you - have a specification <filename>my-packages.nix</filename> like this: - -<programlisting> -with import <nixpkgs> {}; -[ thunderbird - geeqie - ... -] -</programlisting> - - then after any change to this file, you can run: - -<screen> -$ nix-env -f my-packages.nix -ir -</screen> - - to update your profile to match the specification.</para> - </listitem> - - <listitem> - <para>The ‘<literal>with</literal>’ language construct is now more - lazy.

For - instance, you can write <literal>x + y</literal> instead of - <literal>builtins.add x y</literal>, or <literal>x < - y</literal> instead of <literal>builtins.lessThan x y</literal>. - The comparison operators also work on strings.</para> - </listitem> - - <listitem> - <para>On 64-bit systems, Nix integers are now 64 bits rather than - 32 bits.</para> - </listitem> - - <listitem> - <para>When using the Nix daemon, the <command>nix-daemon</command> - worker process now runs on the same CPU as the client, on systems - that support setting CPU affinity.
