option for sgdisk.

+1.0.0 (3/16/2015):
 ------------------
 
+- I'm now building a binary package of gdisk_x64.efi, using the UEFI GPT
+  fdisk package.
+
+- Added partition type for OpenBSD data
+  (824CC7A0-36A8-11E3-890A-952519AD3F61/0xa601). Also mapped 0xa600 to the
+  FreeBSD disklabel type code (516E7CB4-6ECF-11D6-8FF8-00022D09712B). I'm
+  not sure that's 100% correct, but since I can't find references to an
+  OpenBSD disklabel GPT type code, it seems the best choice at the moment.
+
+- Added partition type for Windows Storage Spaces
+  (E75CAF8F-F680-4CEE-AFA3-B001E56EFC2D/0x4202)
+
+- Added -O/--print-mbr option to sgdisk, enabling easier display of MBR
+  data structures without invoking gdisk.
+
+- Updated warning message: "EBR describes a logical partition" now reads
+  "EBR points to an EBR," which is more technically correct.
+
+- Altered warning displayed when run from Windows on non-GPT disk, because
+  Windows on UEFI-based systems is becoming more common.
+
+- Fixed spurious "1" return value in gdisk.
+
 - Small code changes to support compilation as EFI application with the
   UEFI GPT fdisk library
