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

<itemizedlist>

  <listitem>
    <para>The garbage collector now starts deleting garbage much
    faster than before.  It no longer determines liveness of all paths
    in the store, but does so on demand.</para>
  </listitem>

  <listitem>
    <para>Added a new operation, <command>nix-store --query
    --roots</command>, that shows the garbage collector roots that
    directly or indirectly point to the given store paths.</para>
  </listitem>

  <listitem>
    <para>Removed support for converting Berkeley DB-based Nix
    databases to the new schema.</para>
  </listitem>

  <listitem>
    <para>Removed the <option>--use-atime</option> and
    <option>--max-atime</option> garbage collector options.  They were
    not very useful in practice.</para>
  </listitem>

  <listitem>
    <para>On Windows, Nix now requires Cygwin 1.7.x.</para>
  </listitem>

  <listitem>
    <para>A few bug fixes.</para>
