GNU-TK 2025.9.3

• Introduced MSI setup packages for Windows (x64 and ARM64 architectures)
• Improved command-line argument handling in Cygwin-based toolchains (Cygwin, Git, MSYS2), including automatic correction of quirks related to \ character
• Fixed an issue with processing \ character in arguments passed with -l (--command-line) option

GNU-TK 2025.8.2

• Added ability to execute an arbitrary file in GNU environment with -x (--execute) option
• Child processes spawned by gnu-tk tool have GNU_TK_VERSION environment variable set, enabling identification of GNU environments managed by GNU-TK
• For MSYS2 toolkits, MSYS2 environment installation path is used as the toolkit location
• Fixed issue in NPM package that prevented gnu-tk from working with Node v18.x

GNU-TK 2025.7.3

• Added support for BusyBox
• For MSYS2 toolkit, GNU-TK sets GNU_TK_MSYS2_REPOSITORY_PREFIX environment variable to simplify working with MSYS2 packages. This value is precomputed based on the active MSYS2 environment and can be used to construct the names of MSYS2 packages
• BusyBox is now bundled with GNU-TK packages to ensure basic functionality of GNU tools on Windows, even when no specialized GNU toolkit is available

GNU-TK 2025.6.2

This release of GNU-TK brings ability to discover MSYS2 setup instances deployed on Windows by (or for) GHCup utility which is a part of GNU Haskell toolkit. For example, this is the way how MSYS2 is preinstalled on GitHub action runners.

• Portable GNU-TK installations
• Discover MSYS2 setup instances deployed by/for GHCup utility
• Fixed translation of file path arguments for -f (--file) option
• Fixed issue that prevented executable files of an MSYS2 environment to be found

GNU-TK 2025.5.2

This release enhances GNU-TK functionality by adding support for one of the most widely used GNU-compatible toolkits: Git for Windows. While Git itself is not a GNU toolkit, it includes one based on Cygwin. This addition is particularly valuable because Git is frequently preinstalled on CI/CD builders.

• Added support for GNU toolkit coming with Git for Windows
• WSL toolkit commands are executed using a login shell
• GNU toolkit strictness can be activated by GNU_TK_STRICT environment variable

GNU-TK 2025.4.2

• Utilize MSYS2 toolkits installed by msys2/setup-msys2 GitHub action
• Fixed toolkit deduplication

GNU-TK 2025.3.3

• Minimize command line reconstructions which may introduce inaccuracies
• More precise MSYS2 toolkit version detection
• MSYS2 toolkit selection respects the value of MSYSTEM environment variable

GNU-TK 2025.2.5

• Expansion of naturally occurring shebang arguments
• Automatic translation of file path arguments
• Ability to use only a GNU toolkit that operates within the host environment (-i command-line option)

GNU-TK 2025.1.5
