Changelog

Sourced from tox's changelog.

Features - 4.44.0

• Support PEP 751 pylock.toml lock files as dependency input via the pylock configuration option (mutually exclusive with deps). Packages are filtered by extras, dependency groups, and platform markers evaluated against the target Python interpreter, then installed via pip with --no-deps - by :user:gaborbernat. (:issue:3665)

Bug fixes - 4.44.0

• Fix unfactored continuation lines (e.g. pytest \, --remote-data \) being incorrectly skipped when they follow a filtered factor-conditional line ending with \ -- the pending_skip flag now only drops terminal continuation pieces, preserving shared arguments that are themselves continuations - by :user:gaborbernat. (:issue:3802)

v4.43.0 (2026-02-20)

---

Features - 4.43.0

• Add TOML-native generative env_list via product dict syntax -- Cartesian product of factor groups with optional range dicts and exclusions - by :user:gaborbernat. (:issue:3797)

Bug fixes - 4.43.0

• Pass config_settings_build_wheel to pip as --config-settings when installing sdist packages, ensuring the build backend receives config settings during pip's internal wheel build - by :user:gaborbernat. (:issue:3125)
• Fix factor-conditional continuation lines (e.g. cov: coverage run \ / !cov: python \ / somefile.py) where different factor prefixes on consecutive continuation lines caused prefixes to be passed as literal command arguments instead of being filtered - by :user:gaborbernat. (:issue:3796)

Improved documentation - 4.43.0

• Integrate sphinxcontrib-towncrier to render draft changelog entries directly in Sphinx, replacing the manual towncrier draft script - by :user:gaborbernat. (:issue:3201)

---

v4.42.0 (2026-02-20)

---

Features - 4.42.0

• Platform-dependent commands can now be specified using factor syntax without requiring the platform name in the environment name. The current platform (sys.platform value like linux, darwin, win32) is automatically available as an implicit factor, allowing configurations like linux: pytest in INI or factor.linux in TOML conditional expressions to work in any environment. Additionally, TOML configurations can now use factor.NAME in
