UEFITool Changelog

What's new in UEFITool 0.68.0 Alpha

Nov 6, 2023
  • Bugfix release with minor fixes to several regressions in A67, minor parsing improvements and typo fixes, and updates to GUID database.

New in UEFITool 0.67.0 Alpha (Jun 21, 2023)

  • Changes:
  • new GUID database generated by Linux Vendor Firmware Service, about 3x larger than before, major thanks to @hughsie.
  • Fixes:
  • workaround for MAX_PATH limitation for UEFIExtract in Windows (requires Windows 10 1607 or newer OS version, and a registry change), thanks to @NikolajSchlej.
  • fix for CI/CD pipeline to generate proper Windows x86 builds for UEFIExtract and UEFIFind (they were secretly x64 for several past releases), thanks to @NikolajSchlej.

New in UEFITool 0.66.0 Alpha (Apr 24, 2023)

  • Changes:
  • New guids command for UEFIExtract and an update to default extraction modes to include generation of known GUID database (pairs of GUID/String that can be collected from the input file), thanks to @NikolajSchlej.
  • Update to Qt 6.5.0 (LTS) brough seamless cross-platform UI dark mode support, and proper handling of UI mode update, thanks to @NikolajSchlej.
  • QHexEdit2 widget replaced by QHexView5 for Hex View window. The new widget looks nicer in HiDPI and natively supports dark UI mode. Thanks to @Dax89 for creating it and @NikolajSchlej for integration work.
  • Fixes:
  • lots of small fixes for issues found by fuzzing, thanks to @yeggor and @NikolajSchlej
  • small update to built-in GUID database, thanks to @Tody-Guo

New in UEFITool 0.65.0 Alpha (Feb 26, 2023)

  • New features:
  • Replaced AMI NVAR parser with KaitaiStruct-based one. This is another step towards "minimize manual parsing" goal stated by rewriting FIT/ACM/BootGuard parsers in KS, other NVRAM-related parsers will follow in the next updates.
  • Added fuzzing targets for libFuzzer-compatible and AFL-compatible fuzzers, which already uncovered a treasure throve of issues. Fixes are now in development, will be gradually included in the next updates.
  • Added --help (-h) and --version (-v) to UEFIExtract and UEFIFind, this makes them easier to use in scripts.
  • Fixes:
  • Universal macOS package for UEFITool is an app bundle again, thanks to @makigumo and @mikebeaton for reporting.
  • Unicode text search is working again, thanks to @nightgolfer and @mikebeaton for reporting.
  • UEFIExtract and UEFIFind can again be built with slightly older versions of CMake, thanks to @platomav for reporting.
  • Issues in descriptor and capsule parsing are non-fatal now, thanks to @platomav for reporting.
  • "Extract body" action did not work for some section types.

New in UEFITool 0.64.0 Alpha (Feb 13, 2023)

  • New features:
  • native UI dark mode support provided by switching to Qt6 for all release builds. Confirmed working on Windows 11, macOS 13, Ubuntu 22.04 LTS and FreeBSD 13.1 with Qt 6.4.2. Thanks to @yeggor, @vit9696 and @NikolajSchlej.
  • Windows builds split into modern win64 (using static x64 build of Qt 6.4.2) and legacy win32 (using static x86 build of Qt 5.6.3, supports legacy Windows version down to Windows XP). If you use a modern windows, please try win64 build out, as it might have uncaught 64-bit MSVC-specific bugs. Thanks to @NikolajSchlej.
  • Support for AMI v3 protected ranges hash file. Thanks to @cybojanek for the initial pull request and @NikolajSchlej for the final implementation.
  • Fixes:
  • Qt6 started using sse2 for real, and that uncovered a crash reported by @4e4o and @stuarthayhurst, that then got fixed by @NikolajSchlej.
  • CMake config files lacked install targets for all tools, so cmake --install did not work. Does now thanks to @NikolajSchlej.

New in UEFITool 0.63.0 Alpha (Jan 30, 2023)

  • New features:

  • fix for OpenBSD builds, thanks to @klemensn
  • Notes:
  • had to switch to using a monospace font for the whole UI due to HiDPI requirements. If you don't like the new UI look, please open an issue.
