+0.8.1 (?/??/2011):
+------------------
+
+- Changed GPT reading code to use the size encoded in GPT headers to
+  determine how much of the header to use in computing a CRC, with the
+  restriction that the size be equal to or less than the disk's sector
+  size. This should work around problems with libefi in ZFS, which sets the
+  header size to 512 rather than the standard 92. A caveat: If the disk's
+  sector size is larger than the GPTHeader data structure size (512 bytes),
+  then the rest of the sector's contents are ignored and replaced with 0
+  values. This could produce false positives on CRC checks on disks with
+  over-512-byte sector sizes if the header sector is padded with something
+  other than 0 values.
+
+- Fixed bug in new (as of 0.8.0) check that main and backup partition
+  tables are identical on big-endian (PowerPC, etc.) hardware.
