- update to 3.3.0:
- fix ``TOX_LIMITED_SHEBANG`` when running under python3 - by :user:`asottile` (`#931 `_)
- `PEP-517 `_ source distribution support (create a
``.package`` virtual environment to perform build operations inside) by :user:`gaborbernat` (`#573 `_)
- `flit `_ support via implementing ``PEP-517`` by :user:`gaborbernat` (`#820 `_)
- packaging now is exposed as a hook via ``tox_package(session, venv)`` - by :user:`gaborbernat` (`#951 `_)
- Updated the VSTS build YAML to use the latest jobs and pools syntax - by :user:`davidstaheli` (`#955 `_)
- ``--parallel--safe-build`` no longer cleans up its folders (``distdir``, ``distshare``, ``log``). - by :user:`gaborbernat` (`#849 `_)
- Switch pip invocations to use the module ``-m pip`` instead of direct invocation. This could help
avoid some of the shebang limitations. - by :user:`gaborbernat` (`#935 `_)
- Ability to specify package requirements for the tox run via the ``tox.ini`` (``tox`` section under key ``requires`` - PEP-508 style): can be used to specify both plugin requirements or build dependencies. - by :user
:`gaborbernat` (`#783 `_)
- Allow to run multiple tox instances in parallel by providing the
``--parallel--safe-build`` flag. - by :user:`gaborbernat` (`#849 `_)
- A caching issue that caused the ``develop-inst-nodeps`` action, which
reinstalls the package under test, to always run has been resolved. The
``develop-inst-noop`` action, which, as the name suggests, is a no-op, will now
run unless there are changes to ``setup.py`` or ``setup.cfg`` files that have
not been reflected - by @stephenfin (`#909 `_)
