 ** New features
 
+  new --align=<align> commandline option which can have the following values:
+  none:  Use the minimum alignment allowed by the disk type
+  cyl:   Align partitions to cylinders (the default)
+  min:   Use minimum alignment as given by the disk topology information
+  opt:   Use optimum alignment as given by the disk topology information
+  The min and opt values will use layout information provided by the
+  disk to align the logical partition table addresses to actual physical
+  blocks on the disks. The min value is the minimum aligment needed to
+  align the partition properly to physical blocks, which avoids
+  performance degradation. Where as the optimum aligment aligns to a
+  multiple of the physical block size in a way that guarantees optimal
+  performance.
+  The min and opt values will only work when compiled with
+  libblkid >= 2.17 and running on a kernel >= 2.6.31, otherwise they will
+  behave as the none --align value.
+
   libparted: new functions to set per disk (instead of per partition) flags:
   ped_disk_set_flag()
   ped_disk_get_flag()
