-1.0.5 (?/?/2020):
+1.0.10 (?/??/2023):
+-------------------
+
+- Fixed problem that caused sgdisk to crash with errors about being unable
+ to read the disk's partition table when compiled with the latest popt
+ (commit 740, which is pre-release as I type; presumably version 1.19 and
+ later once released).
+
+- Updated guid.cc to deal with minor change in libuuid.
+
+- Fixed potential NULL derefernce bug in sgdisk. Thanks to Damian Kurek
+ for this fix.
+
+- The partition number of "0" can now be used to reference newly-created
+ partitions when the --largest-new=0 option to sgdisk is used. Thanks to
+ David Joaquín Shourabi Porcel for this improvement.
+
+- Make explicit casts in gptcurses.cc to eliminate compiler warnings about
+ mis-matched types in printw() statements.
+
+- Minor code cleanup based on valgrind analysis.
+
+- In previous versions, rEFInd accepted only integer values for partition
+ start points, end points, and sizes, and it interpreted decimal values
+ incorrectly. That is, if you typed "+9.5G" as the partition end point,
+ you'd end up with something just 9 sectors in size. This version now
+ truncates decimal numbers to their integral values, so you'd get a 9 GiB
+ partition instead.
+
+1.0.9 (4/14/2022):
+------------------
+
+- Removed stray debugging code that caused "partNum is {x}" to be printed
+ when changing a partition's name with sgdisk (-c/--change-name).
+
+- Added support for aligning partitions' end points, as well as their start
+ points. This support affects the default partition size when using 'n' in
+ gdisk; it affects the default partition size in cgdisk; and it's activated
+ by the new '-I' option in sgdisk. See the programs' respective man pages
+ for details. This feature is intended to help with LUKS2 encryption, which
+ reacts badly to partitions that are not sized as exact multiples of the
+ encryption block size.
+
+- Added check for too-small disks (most likely to be an issue when trying
+ to use a too-small disk image); program now aborts if this happens.
+
+- Added the ability to build sgdisk and cgdisk for Windows.
+
+- Added new type codes:
+ * FreeBSD nandfs (0xa506)
+ * Apple APFS Pre-Boot (0xaf0b)
+ * Apple APFS Recovery (0xaf0c)
+ * ChromeOS firmware (0x7f03)
+ * ChromeOS mini-OS (0x7f04)
+ * ChromeOS hibernate (0x7f05)
+ * U-Boot boot loader (0xb000)
+ * 27 (!) codes for Fuchsia (0xf100 to 0xf11a)
+
+- Fixed build problems with recent versions of ncurses.
+
+- Fixed bug that caused cgdisk to report incorrect partition attributes.
+
+- Consolidated Makefiles for Linux, FreeBSD, Solaris, macOS, and Windows
+ (32- and 64-bit). The old OS-specific Makefiles remain in case the new
+ consolidated Makefile has problems, but the old ones are deprecated.
+ (The Solaris support in the new Makefile is untested.)
+
+1.0.8 (6/9/2021):
-----------------
+- Fixed double byte swap operation on writes of partition name data on
+ big-endian systems; this is in addition to the double byte swap fix on
+ reading partition label data fixed in 1.0.7. (Thanks to Erik Larsson for
+ both fixes.)
+
+- Added feature to gdisk and sgdisk to enable swapping the byte order of
+ partition names, so as to correct disks already affected by the preceding
+ bug. This option is 'b' on the experts' menu in gdisk and
+ -b/--byte-swap-name in sgdisk. This seems advanced/obscure enough that I
+ don't want to clutter cgdisk's menu with this option, so I haven't added
+ it there.
+
+- Added type code for the Barebox boot loader (0xbb00;
+ 4778ED65-BF42-45FA-9C5B-287A1DC4AAB1).
+
+- Trivial code cleanup.
+
+1.0.7 (3/10/2021):
+------------------
+
+- Fixed bug that caused spurious warnings about the partition table
+ header claiming an invalid size of partition entries when reading
+ some MBR disks.
+
+- Added ARM64 as an architecture for the Mac builds of gdisk and fixparts.
+ The official GPT fdisk binaries of these files for macOS are now
+ "universal" x86-64/ARM64 binaries, so they will run natively on the new M1
+ (ARM64) Macs. The sgdisk and cgdisk binaries, though, remain built only
+ for x86-64, because they rely on libraries that are not easily built in
+ "universal" form.
+
+- Fixed double byte swap operation on partition label data on big-endian
+ CPUs. This resulted in partition names becoming gibberish on such CPUs.
+
+- Added three new type codes:
+ - 0x0701 - Microsoft Storage Replica
+ - 0x0702 - ArcaOS Type 1
+ - 0x8401 - Storage Performance Development Kit (SPDK) block device
+
+1.0.6 (1/13/2021):
+------------------
+
+- Fixed bug that could cause segfault if GPT header claimed partition
+ entries are oversized. See:
+ https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-0256
+
+- Fixed bug that could cause a crash if a badly-formatted MBR disk was
+ read. See:
+ https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-0308
+
+- Renamed the partition type "Freedesktop $BOOT" to "XBOOTLDR partition".
+
+- Added several more Freedesktop partition table type codes (0x8312 through
+ 0x831C).
+
+- Fixed type code definition in diskio-unix.cc that prevented 32-bit builds
+ from correctly handling disks over 4 TiB in size.
+
+- Minor tweaks to get the software to compile on FreeBSD; that seems to have
+ fallen into disrepair.
+
+1.0.5 (2/17/2020):
+------------------
+
- Fixed typos and minor formatting issues in man pages
- Changed number of columns in type code output ("sgdisk -L" and equivalents
in gdisk and cgdisk) from 3 to 2, since some descriptions are long enough
that they're ambiguous with three columns.
+- Makefile change: Add $(LDLIBS) support to enable clean static builds (for
+ libintl).
+
+- You can now put the 0xEE partition last in a hybrid MBR using sgdisk.
+ (Previously, this was possible with gdisk but not with sgdisk.) See the
+ sgdisk man page for details.
+
+- Added numerous type codes for Container Linux, Veracrypt, and
+ Freedesktop.org's Discoverable Partitions Specification
+
+- Partition type name searches are now case-insensitive.
+
+- It's now possible to quit out of partition type name searches by typing
+ "q".
+
+- When changing a partition type code, the default is now the current
+ type code, not a platform-specific type code.
+
+- The UEFI GPT fdisk project
+ (https://sourceforge.net/projects/uefigptfdisk/) hasn't been updated since
+ 2016, and is now broken; binaries don't compile with modern GCC
+ toolchains, and even when dropping back to Ubuntu 14.04, which worked for
+ GPT fdisk 1.0.4, the resulting binary hangs on launch. Therefore, I'm
+ dropping support for the EFI build of gdisk, at least unless and until
+ UEFI GPT fdisk is fixed.
+
+- Apple no longer supports building i386 or "fat" binaries in XCode (or if
+ they do, they're making it hard), so I've removed that support. GPT fdisk
+ macOS binaries are now x86-64 only. Similarly, building now seems to
+ require macOS 10.9 or later, so that's now the minimum macOS version. I've
+ also re-built my Mac build environment and tweaked Makefile.mac
+ appropriately.

If you modify GPT fdisk to get it to compile under another compiler, I
welcome submission of patches.
+
+The following instructions focus on use of MinGW to compile GPT fdisk for
+Windows.
+
+My primary development environment is Ubuntu Linux, using the MinGW
+cross-compiler. This system can compile the gdisk and fixparts binaries with
+no need for additional libraries; after installing MinGW (via the
+g++-mingw-w64 package in Ubuntu, or the equivalent in another distribution),
+you can type "TARGET=win32 make" to compile 32-bit binaries, and
+"TARGET=win64 make" to compile 64-bit binaries. This will attempt to build
+gdisk, sgdisk, and fixparts; but the sgdisk build will fail until you
+install the popt libraries, as described shortly. You can build the other
+binaries by specifying them, as in "TARGET=win64 make gdisk" to build the
+64-bit gdisk binary alone.
+
+If you use Windows, your best bet is likely to be to install the MSYS2
+package (https://www.msys2.org). This package provides MinGW and a package
+management system based on pacman (used by Arch Linux) for installing
+additional libraries. To install the libraries needed to compile sgdisk and
+cgdisk, type "pacman -S mingw-w64-x86_64-popt mingw-w64-x86_64-gettext
+mingw-w64-x86_64-ncurses" if you want to compile 64-bit binaries; change
+'x86_64' to 'i686' for 32-bit packages. This command will install the popt
+library needed by sgdisk and the ncurses library needed by cgdisk, along
+with gettext, which is needed by popt. With these libraries installed, you
+should be able to compile all four Linux programs -- gdisk, cgdisk, sgdisk,
+and fixparts. Typing "make" alone in the MSYS2 shell should build all four
+programs for the host architecture (x86-64 or i686); to compile for the
+other architecture, you must specify it with a "TARGET=" specification, as
+under Linux. (The Makefile does not currently support ARM64 targets for
+Windows.)
+
+If you want to compile sgdisk for Windows under Linux, you can do so;
+however, you must copy the relevant header and library files from a Windows
+installation to Linux. Specifically, you must copy:
+
+ Windows File Linux Directory
+ ------------ ---------------
+ /mingw64/include/popt.h /usr/x86_64-w64-mingw32/include/
+ /mingw64/lib/libpopt.a /usr/x86_64-w64-mingw32/lib/

+ /mingw64/lib/libiconv.a /usr/x86_64-w64-mingw32/lib/
+
+For 32-bit binaries, change /mingw64 to /mingw32 on the Windows source and
+x86_64-w64-mingw32 to i686-w64-mingw32 on the Linux destination.
+
+In theory, you should be able to do something similar to compile cgdisk. The

+In practice, this has not worked for me; the compilation fails with a
+complaint about an undefined reference to 'nanosleep'. My guess is that the
+ncurses version installed in Windows is too new to work with the MinGW
+libraries in Ubuntu (20.04 or 22.04). It's conceivable it would work with
+another distribution, though.
+
+The Makefile is configured to create statically-linked binaries so as to
+simplify installation of the binaries. If you want smaller binaries, you can
+remove the various static options from the Makefile. You can also strip the
+binaries ("make strip") to remove unused code.
