<title>Nixpkgs Release Notes</title>


<section><title>Release 0.10 (October 11, 2006)</title>

<note><para>This release of Nixpkgs requires <link

0.10</link>.</para></note>

<para>This release has the following improvements:</para>

<itemizedlist>

  <listitem><para><filename>pkgs/system/all-packages-generic.nix</filename>
  is gone, we now just have
  <filename>pkgs/top-level/all-packages.nix</filename> that contains
  all available packages.  This should cause much less confusion with
  users.  <filename>all-packages.nix</filename> is a function that by
  default returns packages for the current platform, but you can
  override this by specifying a different <varname>system</varname>
  argument.</para></listitem>

  <listitem><para>TODO: user configurability.  Configuration file in
  <filename>~/.nixpkgs/config.nix</filename>.</para></listitem>

  <listitem><para>Support for new platforms:

    <itemizedlist>

      <listitem><para><literal>i686-cygwin</literal>, i.e., Windows
      (using <link xlink:href="http://www.cygwin.com/">Cygwin</link>).
      The standard environment on <literal>i686-cygwin</literal> by
      default builds binaries for the Cygwin environment (i.e., it
      uses Cygwin tools and produces executables that use the Cygwin
      library).  However, there is also a standard environment that
      produces binaries that use <link
      xlink:href="http://www.mingw.org/">MinGW</link>.  You can use it
      by calling <filename>all-package.nix</filename> with the
      <varname>stdenvType</varname> argument set to
      <literal>"i686-mingw"</literal>.</para></listitem>

      <listitem><para><literal>i686-darwin</literal>, i.e., Mac OS X
      on Intel CPUs.</para></listitem>

      <listitem><para><literal>powerpc-linux</literal>.</para></listitem>

      <listitem><para><literal>x86_64-linux</literal>, i.e., Linux on
      64-bit AMD/Intel CPUs.  Unlike <literal>i686-linux</literal>,
      this platform doesn’t have a pure <literal>stdenv</literal>
      yet.</para></listitem>

    </itemizedlist>

    </para>

  </listitem>
        
  <listitem><para>The default compiler is now GCC 4.1.1.</para></listitem>

  <listitem><para>X11 updated to X.org’s X11R7.1.</para></listitem>

  <listitem><para>Notable new packages:

    <itemizedlist>

      <listitem><para>Opera.</para></listitem>

      <listitem><para>Visual C++ 2005 Express Edition and the Windows
      SDK.</para></listitem>

    </itemizedlist>

    In total there are now around 809 packages in Nixpkgs.</para>

  </listitem>

  
  <listitem><para>It is now <emphasis>much</emphasis> easier to
  override the default C compiler and other tools in
  <literal>stdenv</literal> for specific packages.
  <filename>all-packages.nix</filename> provides two utility
  functions for this purpose: <function>overrideGCC</function> and
  <function>overrideInStdenv</function>.  Both take a
  <literal>stdenv</literal> and return an augmented
  <literal>stdenv</literal>; the formed changes the C compiler, and
  the latter adds additional packages to the front of
  <literal>stdenv</literal>’s initial <envar>PATH</envar>, allowing
  tools to be overriden.</para>

  <para>For instance, the package <varname>strategoxt</varname>
  doesn’t build with the GNU Make in <literal>stdenv</literal>
  (version 3.81), so we call it with an augmented
  <literal>stdenv</literal> that uses GNU Make 3.80:

<programlisting>
strategoxt = (import ../development/compilers/strategoxt) {
  inherit fetchurl pkgconfig sdf aterm;
  stdenv = overrideInStdenv stdenv [gnumake380];
};</programlisting>

  Likewise, there are many packages that don’t compile with the
  default GCC (4.1.1), but that’s easily fixed:

<programlisting>
exult = import ../games/exult {
  inherit fetchurl SDL SDL_mixer zlib libpng unzip;
  stdenv = overrideGCC stdenv gcc34;
};</programlisting>

  </para></listitem>

<section><title>Release 0.9 (January 31, 2006)</title>

<para>There have been zillions of changes since the last release of
Nixpkgs.  Many packages have been added or updated.  The following are
some of the more notable changes:</para>

<itemizedlist>

  <listitem><para>Distribution files have been moved to <link
  xlink:href="http://nix.cs.uu.nl/" />.</para></listitem>

  <listitem><para>The C library on Linux, Glibc, has been updated to
  version 2.3.6.</para></listitem>

  <listitem><para>The default compiler is now GCC 3.4.5.  GCC 4.0.2 is
  also available.</para></listitem>

  <listitem><para>The old, unofficial Xlibs has been replaced by the
  official modularised X11 distribution from X.org, i.e., X11R7.0.
  X11R7.0 consists of 287 (!) packages, all of which are in Nixpkgs
  though not all have been tested.  It is now possible to build a
  working X server (previously we only had X client libraries).  We
  use a fully Nixified X server on NixOS.</para></listitem>

  <listitem><para>The Sun JDK 5 has been purified, i.e., it doesn’t
  require any non-Nix components such as
  <filename>/lib/ld-linux.so.2</filename>.  This means that Java
  applications such as Eclipse and Azureus can run on
  NixOS.</para></listitem>

  <listitem><para>Hardware-accelerated OpenGL support, used by games
  like Quake 3 (which is now built from source).</para></listitem>

  <listitem><para>Improved support for FreeBSD on
  x86.</para></listitem>

  <listitem><para>Improved Haskell support; e.g., the GHC build is now
  pure.</para></listitem>

  <listitem><para>Some support for cross-compilation: cross-compiling
  builds of GCC and Binutils, and cross-compiled builds of the C
  library uClibc.</para></listitem>

  <listitem><para>Notable new packages:

    <itemizedlist>

      <listitem><para>teTeX, including support for building LaTeX
      documents using Nix (with automatic dependency
      determination).</para></listitem>
      
      <listitem><para>Ruby.</para></listitem>

      <listitem><para>System-level packages to support NixOS,
      e.g. Grub, GNU <literal>parted</literal> and so
      on.</para></listitem>

      <listitem><para><literal>ecj</literal>, the Eclipse Compiler for
      Java, so we finally have a freely distributable compiler that
      supports Java 5.0.</para></listitem>

      <listitem><para><literal>php</literal>.</para></listitem>

      <listitem><para>The GIMP.</para></listitem>

      <listitem><para>Inkscape.</para></listitem>

      <listitem><para>GAIM.</para></listitem>

      <listitem><para><literal>kdelibs</literal>.  This allows us to
      add KDE-based packages (such as
      <literal>kcachegrind</literal>).</para></listitem>

<section><title>Release 0.8 (April 11, 2005)</title>

<para>This release is mostly to remain synchronised with the changed
hashing scheme in Nix 0.8.</para>

<para>Notable updates:

<itemizedlist>

  <listitem><para>Adobe Reader 7.0</para></listitem>

  <listitem><para>Various security updates (zlib 1.2.2, etc.)</para></listitem>

<section><title>Release 0.7 (March 14, 2005)</title>

<itemizedlist>

<listitem>

  <para>The bootstrap process for the standard build
  environment on Linux (stdenv-linux) has been improved.  It is no
  longer dependent in its initial bootstrap stages on the system
  Glibc, GCC, and other tools.  Rather, Nixpkgs contains a statically
  linked bash and curl, and uses that to download other statically
  linked tools.  These are then used to build a Glibc and dynamically
  linked versions of all other tools.</para>

  <para>This change also makes the bootstrap process faster.  For
  instance, GCC is built only once instead of three times.</para>

  <para>(Contributed by Armijn Hemel.)</para>

</listitem>

<listitem>

  <para>Tarballs used by Nixpkgs are now obtained from the same server
  that hosts Nixpkgs (<link
  xlink:href="http://catamaran.labs.cs.uu.nl/" />).  This reduces the
  risk of packages being unbuildable due to moved or deleted files on
  various servers.</para>

</listitem>

<listitem>

  <para>There now is a generic mechanism for building Perl modules.
  See the various Perl modules defined in
  pkgs/system/all-packages-generic.nix.</para>
