Full Changelog: tox-dev/tox@4.52.1...4.53.0

Changelog

Sourced from tox's changelog.

Features - 4.53.0

• TOML env_list now accepts bare range dicts ({ prefix = "3.", start = 12, stop = 14 }) and bare labeled dicts ({ ecosystem = ["oci", "python"] }) as top-level items, removing the { product = [...] } wrapper when there is only a single factor group - by :user:gaborbernat. (:issue:3923)

Bug fixes - 4.53.0

• Nesting a range or labeled dict inside a product factor-group list now raises a clear error pointing at the un-nesting fix, instead of silently producing a malformed environment name - by :user:gaborbernat. (:issue:3923)

---

v4.52.1 (2026-04-09)

---

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)
