 Version 1.02.04 - 
 ============================
+  Bring dmsetup man page up-to-date.
   Use name-based device refs if kernel doesn't support device number refs.
   Fix memory leak (struct dm_ioctl) when struct dm_task is reused.
   If _create_and_load_v4 fails part way through, revert the creation.

 List device names.  Optionally only list devices that have at least
 one target of the specified type.  Optionally execute a command for
 each device.  The device name is appended to the supplied command.
+--tree displays dependencies between devices as a tree.
+It accepts a comma-separate list of options.
+Some specify the information displayed against each node:
+device/nodevice; active, open, rw, uuid.
+Others specify how the tree is displayed:
+ascii, utf, vt100; compact, inverted, notrunc.

 but has not yet completed will be flushed.  Any further I/O to that
 device will be postponed for as long as the device is suspended.
