Changelog

Sourced from tox's changelog.

v4.4.6 (2023-02-21)

Bugfixes - 4.4.6

- Plugins are now able to access tox.ini config sections using a custom prefix with the same suffix / name as a tox
  ``testenv`` - by :user:`masenf` (:issue:`2926`)
v4.4.5 (2023-02-07)
Bugfixes - 4.4.5

• Ignore labels when tox will provision a runtime environment (.tox) so that environment configurations which depend on provisioned plugins or specific tox versions are not accessed in the outer tox process where the configuration would be invalid - by :user:masenf. (:issue:2916)

v4.4.4 (2023-01-31)

Bugfixes - 4.4.4

- Forward ``HOME`` by default - by :user:`gschaffner`. (:issue:`2702`)
v4.4.3 (2023-01-30)
Bugfixes - 4.4.3

• Tox will now expand self-referential extras discovered in package deps to respect local modifications to package metadata. This allows a package extra to explicitly depend on another package extra, which previously only worked with non-static metadata - by :user:masenf. (:issue:2904)

v4.4.2 (2023-01-25)

Bugfixes - 4.4.2

- Allow the user configuration file (default ``<appdir>/tox/config.ini``) to be overridden via the
  ``TOX_USER_CONFIG_FILE`` environment variable. Previously tox was looking at the ``TOX_CONFIG_FILE`` to override the
  user configuration, however that environment variable is already used to override the main configuration - by
  :user:`masenf`. (:issue:`2890`)
v4.4.1 (2023-01-25)
