Changelog

Sourced from tox's changelog.

Bug fixes - 4.53.1

• Hardening pass on user-facing logging and config parsing:

  • Mask secret-looking --key=value flag values in command logs (terminal warnings, .tox/<env>/log/*.log, and Outcome __repr__) using the same keyword regex previously applied to environment variable values.
  • Resolve PEP 723 script paths and reject any that escape tox_root; cap the script read at 5 MiB so a symlink to /dev/zero cannot exhaust memory.
  • Replace eval() of a constructed Literal[...] string in the CLI parser with a direct Literal[tuple(action.choices)] subscript.
  • Pass timeout=30 to urlopen when fetching a remote requirements file so a slow or unresponsive mirror cannot hang tox indefinitely. (:issue:3924)

• Allow the generated TOML schema to validate array values for deps. (:issue:3929)

• Correct type annotations for ArgumentParser.parse_args and parse_known_args overrides following typeshed PR [#15613](https://github.com/tox-dev/tox/issues/15613) <https://github.com/python/typeshed/pull/15613>_, which widened the args parameter from Sequence[str] to Iterable[str]. The narrower type in tox's overrides violated the Liskov substitution principle and caused invalid-method-override errors with ty 0.0.33. Also correct the option_spec annotation in docs/tox_conf.py to ClassVar[dict[str, Callable[[str], Any]]] matching the docutils stubs type. (:issue:3932)

v4.53.0 (2026-04-14)

---

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 →
