Version 2.02.83 -
===================================
+ Updating man pages for pvcreate, pvremove, pvresize, pvscan.
Avoid rebuilding of uuid validation table.
Always use O_DIRECT when opening block devices to check for partitioning.
Improve lvcreate "insufficient extents" errors to "insufficient free space".
