Changelog

Sourced from tox's changelog.

Bug fixes - 4.52.1

• Changing a resolution-affecting environment variable via set_env (e.g. PIP_INDEX_URL) now invalidates the install cache and triggers a reinstall, rather than incorrectly reusing the cached environment - by :user:gaborbernat. (:issue:3917)
• Use normalize_isa from python-discovery for architecture factor matching, supporting aliases like i686 → x86 and aarch64 → arm64 - by :user:rahuldevikar. (:issue:3919)

---

v4.52.0 (2026-03-30)

---

Features - 4.52.0

• Add virtualenv-pep-723 runner that reads dependencies and Python version from :PEP:723 inline script metadata — no need to duplicate them in tox config - by :user:gaborbernat. (:issue:3897)
• Support escaped dots (\.) in -x/--override keys, allowing overrides to target environments with dots in their names such as py3.14 - by :user:gaborbernat. (:issue:3910)

Bug fixes - 4.52.0

• Auto-generate the manpage from the CLI argparse parser at wheel build time, fixing broken section headers and documenting all commands and options - by :user:gaborbernat. (:issue:3878)

Miscellaneous internal changes - 4.52.0

• Remove unsupported --remote flag from gh repo fork in the update-schemastore workflow, as recent versions of gh no longer accept it - by :user:rahuldevikar. (:issue:3908)

---

v4.51.0 (2026-03-27)

---

Features - 4.51.0

• Add base_python_file configuration option to read the base Python version from a file (e.g. .python-version), similar to GitHub Actions' python-version-file - by :user:rahuldevikar (:issue:3894)

Bug fixes - 4.51.0

• Prevent implicit machine ISA (e.g. arm64, x86_64) from overriding explicit architecture factors in environment names, fixing cross-architecture conflicts in multiline factor conditionals - by :user:rahuldevikar. (:issue:3903)
• Nested environment list configuration values are now properly parsed, validated and expanded by the TOML parser. This allows you to use generative environment lists in tox-gh via the TOML format. Previously this was only possible
