Changelog

Sourced from tox's changelog.

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

• When the constraints configuration option is set, constrain_package_deps and use_frozen_constraints are now ignored. Previously, both the user-provided constraints file and the auto-generated constraints file were passed to pip during install_package_deps, which could cause resolver conflicts when the same package appeared in both files - by :user:gaborbernat. (:issue:3945) (:issue:3945)

v4.54.0 (2026-05-12)

---

Features - 4.54.0

• Declare the runtime dependencies of the tox.pytest plugin (pytest, devpi-process and pytest-mock) under a new testing extra, so plugin authors can pull them in via tox[testing] - by :user:gaborbernat. (:issue:3938, :issue:3940)

Bug fixes - 4.54.0

• Extend the generated TOML schema to cover every replace table form (env, ref, posargs, glob, if), including conditional replacements used inside commands. A guard test asserts the schema stays in sync with the loader implementation so future replace types cannot be added without a corresponding schema entry. (:issue:3939)

v4.53.1 (2026-05-02)
