Changelog

Sourced from tox's changelog.

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.

  -- by :user:webknjaz (:issue:3598)

v4.29.0 (2025-08-29)

Features - 4.29.0

- A new tox life cycle event is now exposed for use via :doc:`Plugins
  API </plugins>` -- by :user:`webknjaz`.
The corresponding hook point is :func:tox_extend_envs &lt;tox.plugin.spec.tox_extend_envs&gt;. It allows plugin authors to
declare ephemeral environments that they can then populate through
the in-memory configuration loader interface.
