CHANGELOG - platform/external/gptfdisk - Gitiles

 0.5.1:
 ------

 - Made some minor edits to the man page.

 - Incorporated RPM .spec file changes contributed by Scott Collier
   (boodle11@gmail.com).

 - Changed method of locating and loading backup GPT data, to use the
   main header's pointer, if it's valid, rather than seeking to the
   end of the disk.

 - Added 'e' option (relocate backup GPT data structures) to the experts'
   menu.

 0.5.0:
 ------

 - Added GPT-to-MBR conversion function. It's very limited, but potentially
   useful in some cases.

 - Fixed bug that caused incorrect file sizes to be reported on 32-bit
   Linux, thus causing problems when editing partition tables in disk images
   or when loading GPT backup files.

 - Fixed bug that caused bogus CRC error reports when loading backup GPT
   data.

 - Reorganized menus. There are now three: the main menu, the experts' menu,
   and the recovery & transformation menu. The last of these has most of the
   items that had been on the earlier versions' experts' menu.

 - Added ability to re-load the MBR and generate a fresh GPT from it. This
   is normally identical to quitting and re-running the program, but it
   could be handy if, say, the GPT partitions on a hybrid configuration are
   badly messed up; this will enable using the hybridized partitions as the
   starting point for a new GPT setup.

 - The program now generates CHS values for hybrid and GPT-to-MBR conversion
   MBRs. For the moment, the assumption is the maximum number of heads and
   sectors per track (255 and 63, respectively), although the bulk of the
   code supports other values -- it'd just be awkward to enter the data in
   the user interface.

 - Fixed minor display bug that caused number of sectors on the disk to be
   shown as 0 on large disks when running 32-bit binaries.

 - Reverted 0.4.2's zap (destroy GPT) changes, since I don't want to wipe
   out a valid MBR if the user created that MBR over an older GPT without
   first properly wiping out the GPT, and the user now wants to wipe out
   the GPT.

 - Reformatted and edited the man page. Aside from edits related to the
   preceding program changes, I've altered the markup slightly and trimmed
   much of the more tutorial information from the man page to better
   conform to typical terse man page style.

 0.4.2:
 ------

 - Code cleanup.

 - Fixed very small formatting bug in display of hex code when a match isn't
   found when converting from an MBR/gdisk hex code to a GUID type code.

 - Added the ability to work on disk image files (raw files for virtual
   machines, backup images, etc.). The program assumes that all such disk
   image files have 512-byte sectors.

 - Added verification prompt to 'o' main-menu option to avoid accidental
   erasures of all partitions.

 - The "destroy GPT data structures" option ('z' on the experts' menu) now
   also destroys all EFI GPT (0xEE) partitions in the MBR.

 - Added an extra warning to the "destroy GPT data structures" option if an APM
   or BSD disklabel was detected on the disk.

 - Added a buffer flush after destroying GPT data structures, to get the OS
   to read the new (empty or MBR-only) partition table.

 - Fixed bug that allowed entry of nonexistent partition numbers when creating
   a hybrid MBR.

 0.4.1:
 ------

 - Code cleanup/re-organization

 - Partition creation function ('n' on main menu) now uses the start of the
   largest available chunk of free space rather than the first available
   sector as the default starting sector number. This should enable easier
   partition creation if there are small bits of free space on the disk.

 - You can now specify the end point of a partition by using a minus sign,
   in which case the end point is the default value minus the specified
   size. For instance, "-200M" creates a partition that ends 200MiB before
   the default end point.

 - You can now specify the start point of a partition by using a plus or
   minus sign, in which case the start point is the specified distance from
   the start (+) or end (-) of free space. This is exactly the same as the
   new rules for entry of the end point, except that the default value is
   set differently.

 - Deleting a partition now checks for a matching hybrid MBR partition, and
   if one is found, it's deleted. Any empty space that then surrounds the
   0xEE (EFI GPT) MBR partitions is then added to the nearby 0xEE partition.
   If no non-0xEE partitions are left, a fresh protective MBR is generated.

 - Added hybrid MBR consistency check to the verify ('v') option and to
   pre-write checks. If non-0xEE/non-0x00 MBR partitions without
   corresponding GPT partitions are found, the user is warned. This finding
   does NOT prevent writing the partition table, though.

 - Added non-destructive write test when opening the device file, in order
   to detect the problem with FreeBSD being unable to write to disks with
   mounted partitions (or other potential problems).

 0.4.0:
 ------

 - Added support for BSD disklabels. The program can now convert disks that
   use "raw" disklabels, with the caveat that the first partition will
   almost certainly need to be deleted because it'll overlap the main GPT
   header; and convert disklabels contained within a GPT (or a former MBR,
   converted to GPT) partition. In the latter case, the 'b' main menu option
   is used.

 - Added support for compiling on FreeBSD.

 - Fixed bug that could cause crashes or incomplete sorts when sorting
   the partition table.

 - New partitions, including converted ones, now take on the name of the
   partition type as a default name.

 - Reorganized some code; created a separate C++ class for GPT partitions
   (GPTPart), which replaced a struct and enabled moving code from the
   bloated GPTData class into GPTPart.

 - Fixed a bug that produced spurious warnings about unknown sector sizes
   when loading a backup file.

 0.3.5:
 ------

 Note: This version was not officially publicly released; I wanted to test
 the big-endian support while developing 0.4.0.

 - Tweaked the disk type identification code to warn users to re-sync their
   hybrid MBRs when one is detected.

 - Tweaked MBR-reading code to ignore 0xEE (EFI GPT) partitions. This will
   only have an effect on a poorly partitioned MBR disk that contains an
   inappropriate EFI GPT partition, or when attempting to recover a
   corrupted disk by using the hybrid MBR for data recovery.

 - Added big-endian (PowerPC, etc.) support!

 - Added code to identify and warn of the presence of an Apple Partition
   Map (APM) on the disk.

 - Enabled MBR conversion code to handle multiple logical partitions.

 0.3.4:
 ------

 - Fixed bug that enabled (possibly accidental) entry of MBR type codes of
   0x00 in GPTData::MakeHybrid(). The fix also enables entry of default
   type code by pressing the Enter key when prompted. Applied a similar
   fix to the entry of the type code for the second protective partition,
   if one is used.

 - Fixed a typo: "sectors" was spelled "sectprs" in one spot!

 - Fixed bug that caused default entry for end sector to be refused if an
   initial value using a plus sign (e.g., "+20G") was also refused.

 0.3.3:
 ------

 - Gave users control over the way MBR partitions are assigned to slots in a
   hybrid MBR setup; the original method (putting the 0xEE partition after
   the real partitions) works well for non-boot disks, but both GRUB and
   GRUB2 become confused by this type of setup, so it needs changing.

 - Changed "blocks" to "sectors" in GPT and MBR table displays.

 - Added "Boot" column to MBR table display; shows an asterisk (*) when the
   partition's status is bootable.

 0.3.2:
 ------

 - Changed __DARWIN_UNIX03 to __APPLE__ as code to enable MacOS X support.

 - Added the ability to create a hybrid MBR ('h' on experts' menu). This was
   motivated by my discovery that Windows 7 remains brain-dead when it comes
   to the ability to boot from a GPT disk, at least on BIOS-based machines.

 - Added 'z' option to experts' menu, to destroy GPT data structures and
   exit. The intent is to use this feature to enable subsequent partitioning
   of the disk using fdisk or other GPT-unaware tools. (GNU Parted will wipe
   the GPT data structures itself when you create a new MBR ["msdos
   disklabel," in Parted parlance], so using Parted is another option.)

 - Slightly altered the effect of the 'o' command on the main menu. It now
   blanks out the protective MBR, as well as the GPT data.

 0.3.1:
 ------

 - Added Mac OS X support, provided as a patch by David Hubbard
   (david.c.hubbard@gmail.com).

 - Fixed bug in disksize() function on Mac OS. (Possibly dependent on the
   kernel and/or GCC version.) The disk size, of type uint64_t, was not
   being passed correctly, so I reorganized the function to return it as
   the function's return value rather than as a parameter. This seems to
   work OK on my Mac OS test system and on both 32- and 64-bit Linux
   systems.

 - Fixed off-by-one bug in GPTData::FindLastAvailable().

 - Fixed bug that caused display of options after a disk-write error.

 - Fixed several incorrect MacOS X partition type GUIDs, thanks to Yves
   Blusseau (1otnwmz02@sneakemail.com).

 0.3.0:
 ------

 - Changed version number to 0.3.0, reflecting the fact that I've received
   no significant bug reports and so am elevating the program to "beta"
   status. This change also entailed altering the warning the program
   displays when saving partition table changes.

 - Fixed minor bug in CHS geometry of the protective MBR's type EE partition
   (was producing 0x000200 as the start value, but should be 0x000100).
   Should be a non-critical bug since the protective MBR partition
   definition is only there to keep MBR-only disk utilities from messing
   with the disk.

 - Added ability to enter GUIDs as single massive strings rather than in
   chunks.

 0.2.2:
 ------

 - Added #include directives required to compile the program using GCC
   4.4.0.

 0.2.1:
 ------

 - Fixed partition numbering problem in reports of partition overlaps in
   verification function.

 - Fixed 1-sector partition size problem when creating new partitions
   (partitions were 1 sector too big when using the +size option).

 - Changed BytesToSI() to display values in bytes without decimal points
   (e.g., "512 bytes" rather than "512.0 bytes").

 - Added GPTData class member functions to retrieve GPT data structure
   locations on disk; used in my internal-use-only GPT-wiping program.

 - Eliminated the "a reboot is recommended" notice after writing the
   partition table.

 - Added notice after sorting the partition table to the effect that
   editing /etc/fstab and/or the boot loader files may be required.

 - Fixed bug in MBR-reading function that caused 0x0f (Win95 LBA) and 0x85
   (Linux extended) extended partitions to not be read.

 - Fixed bug in GetLastSector() (in support.cc) that would have prevented
   correct user entry of over-32-bit sector numbers on 32-bit systems.

 - Made some changes/corrections to the partition type list in
   parttypes.cc. Most of these were based on newly-discovered MBR type
   codes for Apple (Mac OS X) filesystems.

 - General code cleanup (setting explicit casts, etc.)
