Release Notes

gptgen 1.3 is primarily a bug fix release with a few new features that have accumulated over the years since the 1.2.1 release.

  • Added support for building on macOS. Thanks to Jan Kaiser!
  • Added support for getting the capacity of a non-sparse disk image on Unix-like platforms (Linux and macOS). This is an alternative to operating directly on a block device.
  • Added an integration test suite for automated testing.
  • Fixed writing the backup GPT header to disk. This bug only affected -w/--write mode.
  • Fixed building with modern CMake (>= 4.0), and bumped the minimum supported CMake version to CMake 3.15.
  • Fixed seeking in files to read/write blocks on Unix-like platforms (Linux and macOS). This does not affect Windows.
  • Fixed a memory leak writing a file with a backup of the MBR.
