Changelog

Sourced from tox's changelog.

Features - 4.56.0

• Derive :ref:virtualenv_spec automatically: when an environment targets a Python version the installed :pypi:virtualenv can no longer create (e.g. py38 with virtualenv 21.5+), tox now pins the newest virtualenv that still supports it and bootstraps it for that environment only. The downgrade happens only when every base_python candidate is unsupported, so environments targeting current interpreters are unaffected. This fixes py38 (and other end-of-life interpreters) being silently skipped after a virtualenv upgrade - by :user:gaborbernat. (:issue:3965) (:issue:3965)

Bug fixes - 4.56.0

• The default value of skip_missing_interpreters changed from True to False — missing interpreters now fail the run by default, matching tox 3 behavior. The tox 4 rewrite unintentionally changed this default. To restore the previous (incorrect) behavior, set skip_missing_interpreters = true in your tox configuration or pass --skip-missing-interpreters on the command line. (:issue:3965)

Improved documentation - 4.56.0

• Fix nested list items being rendered with continued numbering instead of as sub-items in development.rst, onboarding.rst and explanation.rst. (:issue:3960)
• Replace stale http://tox.readthedocs.org URL with https://tox.wiki in pyproject.toml (Homepage), .github/CONTRIBUTING.md, and .github/PULL_REQUEST_TEMPLATE.md. (:issue:3963)

v4.55.1 (2026-06-03)

---

Bug fixes - 4.55.1

• TOX_OVERRIDE (and -x/--override) now propagates through configuration references. Previously, overriding a base value that was later referenced via {[section]key} (ini) or {replace = "ref", of = [...]} (toml) was ignored because reference resolution read the raw file value, bypassing the override system - by :user:tales-aparecida. (:issue:3950) (:issue:3950)

v4.55.0 (2026-05-28)

---

Features - 4.55.0

• Automatically pass the TERMINFO environment variable to tox subprocesses if the output is a TTY. This variable is used by Ghostty to communicate terminal capabilities to programs. (:issue:3946)

Bug fixes - 4.55.0
