Full Changelog: tox-dev/tox@4.54.0...4.55.0

Changelog

Sourced from tox's changelog.

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)

---

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)
