 Version 2.02.54 -
 =====================================
+  Add implict pvcreate support to vgcreate and vgextend.
   Correct example.conf to indicate that lvm2 not lvm1 is the default format.
   Remove an unused stray LVM1_SUPPORT ifdef.
   Only include selinux libs in libdevmapper.pc when selinux build enabled.
