Changelog

Sourced from tox's changelog.

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)
Bugfixes - 4.4.1

• In tox 4.4.0 constrain_package_deps was introduced with a default value of True. This has been changed back to False, which restores the original behavior of tox 4.3.5 - by :user:masenf. (:issue:2897)

v4.4.0 (2023-01-25)

Features - 4.4.0

- Test environments now recognize boolean config keys ``constrain_package_deps`` (default=true) and ``use_frozen_constraints`` (default=false),
  which control how tox generates and applies constraints files when performing ``install_package_deps``.
If constrain_package_deps is true (default), then tox will write out {env_dir}{/}constraints.txt and pass it to
pip during install_package_deps. If use_frozen_constraints is false (default), the constraints will be taken
from the specifications listed under deps (and inside any requirements or constraints file referenced in deps).
Otherwise, list_dependencies_command (pip freeze) is used to enumerate exact package specifications which will
