+0.6.3 (2/3/2010):
+------------------
+
+- Fixed serious data corruption bug on big-endian (PowerPC and similar)
+ systems.
+
+- Changed several GPT fdisk Solaris type codes to correct a duplicate
+
+- Corrected error in GPT fdisk type codes for NetBSD LFS and NetBSD RAID;
+ they were identical, but I've now changed NetBSD RAID to A906, which
+ is unique.
+
+- Added GUID for IBM General Parallel File System (GPFS) partition type
+ code. Somewhat arbitrarily set it to use the 7501 number (MBR code 0x75
+ is used by IBM PC/IX, so it's at least the right company, by my loose
+ numbering rules....).
+
+- Improved GUID generation. Prior versions generated completely random
+ numbers for GUIDs. This works, but is technically a violation of the
+ spec. Unix versions now employ libuuid to generate GUIDs in a more
+ correct way. The Windows version still generates random numbers, though.
+
+- Turned PartTypes class into a derived class of GUIDData, and renamed
+ it to PartType.
+
+- Created new GUIDData class, to replace the original GUIDData struct.
+
0.6.2 (1/29/2010):

To compile GPT fdisk, you must have appropriate development tools

+The GUIDs generated by the program to uniquely identify disks and

+practice, this has caused me no problems; however, it's conceivable that
+some disk utility will complain. The Unix versions of GPT fdisk generate
