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
be written to the constraints file.
In previous releases, conflicting package dependencies would silently override the deps named in the configuration,
resulting in test runs against unexpected dependency versions, particularly when using tox factors to explicitly test
with different versions of dependencies - by :user:masenf. (:issue:2386)
Bugfixes - 4.4.0

• When parsing command lines, use shlex(..., posix=True), even on windows platforms, since non-POSIX mode does not handle escape characters and quoting like a shell would. This improves cross-platform configurations without hacks or esoteric quoting.

  To make this transition easier, on Windows, the backslash path separator will not treated as an escape character unless it preceeds a quote, whitespace, or another backslash chracter. This allows paths to mostly be written in single or double backslash style.

  Note that double-backslash will no longer be escaped to a single backslash in substitutions, instead the double backslash will be consumed as part of command splitting, on either posix or windows platforms.

  In some instances superfluous double or single quote characters may be stripped from arg arrays in ways that do not occur in the default windows cmd.exe shell - by :user:masenf. (:issue:2635)

Improved Documentation - 4.4.0

- Add infromation when command from ``list_dependencies_command`` configuration option is used. (:issue:`2883`)
v4.3.5 (2023-01-18)
Bugfixes - 4.3.5
- When building a ``wheel`` or ``editable`` package with a PEP 517 backend, no
  longer pass an empty ``metadata_directory`` to the backend ``build_wheel`` or
  ``build_editable`` endpoint.
Some backends, such as PDM and poetry, will not generate package metadata in
the presence of a metadata_directory, even if it is empty.
