Changelog

Sourced from tox's changelog.

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 :pr:3591 turned out to not work well with tox run. It was fixed internally, not to exhaust the underlying iterator on the first use.
