 | |
|     <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>
 | |
|     <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>

|     <para>Removed the <option>--use-atime</option> and
 | |

 | |
|     not very useful in practice.</para>
