The Haskell packages infrastructure has been re-designed from the ground up.
|
|

|
|
<link xlink:href="http://hackage.haskell.org/">Hackage</link>, i.e. well over
|
|
8000 Haskell packages. Further information and usage instructions for the
|
|
improved infrastructure are available at <link

|
xlink:href="https://nixos.org/wiki/Haskell">https://nixos.org/wiki/Haskell</link>.

<listitem><para>Steam now doesn't need root rights to work. Instead of using

<literal>*-steam-chrootenv</literal>, you should now just run <literal>steam</literal>.
|
|
<literal>steamChrootEnv</literal> package was renamed to <literal>steam</literal>,

and old <literal>steam</literal> package -- to <literal>steamOriginal</literal>.

The default <literal>NIX_PATH</literal> for NixOS now includes
|

<literal>/nix/var/nix/profiles/per-user/root/channels</literal>, so it's

|
Moreover, whenever a <command>nixos-rebuild <action>
|
|
--upgrade</command> is issued, every channel that includes a file
|
|
called <filename>.update-on-nixos-rebuild</filename> will be upgraded
|
|
alongside of the <literal>nixos</literal> channel.
