Changelog

Sourced from tox's changelog.

v4.30.3 (2025-10-02)

Bugfixes - 4.30.3

- Fix incorrect type annotation in ``PythonPathPackageWithDeps.__init__()``
  where ``deps`` was annotated as ``Sequence[Package]`` but should be
  ``Sequence[Requirement]`` to match actual runtime usage - by :user:`PreistlyPython` (:issue:`3607`)
- Fix ``None`` appearing as the config filename in error output
  when the user's default config file is corrupt. - by :user:`kurtmckee` (:issue:`3611`)
v4.30.2 (2025-09-04)
Bugfixes - 4.30.2

• Previously, when tox ran in an automatically provisioned environment, it could hang waiting for a PEP 517 build backend if used in conjunction with the --installpkg option. This has been fixed by properly tearing down the automatically provisioned environment after the tests.
  • by :user:vytas7 (:issue:3600)

v4.30.1 (2025-09-03)

Bugfixes - 4.30.1

- Prevent tox from hanging upon exit due to orphaned build threads and subprocesses when the ``--installpkg`` option is
  used with *sdist*.
  - by :user:`vytas7` (:issue:`3530`)
v4.30.0 (2025-09-03)
Features - 4.30.0

• Add __TOX_ENVIRONMENT_VARIABLE_ORIGINAL_CI, which passes through the CI variable if present. This is intended for use by other libraries to detect if tox is running under CI. (:issue:3442)

Bugfixes - 4.30.0

- Makes the error message more clear when pyproject.toml file cannot be loaded
  or is missing expected keys. (:issue:`3578`)
- The :func:`tox_extend_envs() hook <tox.plugin.spec.tox_extend_envs>`
  recently added in :pull:`3591` turned out to not work well with
  ``tox run``. It was fixed internally, not to exhaust the underlying
  iterator on the first use.
