v20.10.0 (2021-11-01)
---------------------

Features - 20.10.0
~~~~~~~~~~~~~~~~~~
- If a ``"venv"`` install scheme exists in ``sysconfig``, virtualenv now uses it to create new virtual environments.
  This allows Python distributors, such as Fedora, to patch/replace the default install scheme without affecting
  the paths in new virtual environments.
  A similar technique `was proposed to Python, for the venv module <https://bugs.python.org/issue45413>`_ - by ``hroncok`` (`#2208 <https://github.com/pypa/virtualenv/issues/2208>`_)
- The activated virtualenv prompt is now always wrapped in parentheses. This
  affects venvs created with the ``--prompt`` attribute, and matches virtualenv's
  behaviour on par with venv. (`#2224 <https://github.com/pypa/virtualenv/issues/2224>`_)

Bugfixes - 20.10.0
~~~~~~~~~~~~~~~~~~
- Fix broken prompt set up by activate.bat - by :user:`SiggyBar`. (`#2225 <https://github.com/pypa/virtualenv/issues/2225>`_)

- Special-case ``--prompt .`` to the name of the current directory - by :user:`rkm`. (`#2220 <https://github.com/pypa/virtualenv/issues/2220>`_)
- Add libffi-8.dll to pypy windows `#2218 <https://github.com/pypa/virtualenv/issues/2218>`_ - by :user:`mattip`

Bugfixes - 20.9.0
~~~~~~~~~~~~~~~~~
- Fixed path collision that could lead to a PermissionError or writing to system
  directories when using PyPy3.8 - by :user:`mgorny`. (`#2182 <https://github.com/pypa/virtualenv/issues/2182>`_)
- Upgrade embedded setuptools to ``58.3.0`` from ``58.1.0`` and pip to ``21.3.1`` from ``21.2.4`` - by
  :user:`gaborbernat`. (`#2205 <https://github.com/pypa/virtualenv/issues/2205>`_)
- Remove stray closing parenthesis in activate.bat - by :user:`SiggyBar`. (`#2221 <https://github.com/pypa/virtualenv/issues/2221>`_)


v20.8.1 (2021-09-24)
--------------------

Bugfixes - 20.8.1
~~~~~~~~~~~~~~~~~
- Fixed a bug where while creating a venv on top of an existing one, without cleaning, when seeded
  wheel version mismatch occurred, multiple ``.dist-info`` directories may be present, confounding entrypoint
  discovery - by :user:`arcivanov` (`#2185 <https://github.com/pypa/virtualenv/issues/2185>`_)
- Bump embed setuptools from ``58.0.4`` to ``58.1.0`` - by :user:`gaborbernat`. (`#2195 <https://github.com/pypa/virtualenv/issues/2195>`_)

v20.0.2 (2020-02-11)
--------------------

  ``app-data`` :option:`seeder` - by :user:`gaborbernat`. (`#997 <https://github.com/pypa/virtualenv/issues/997>`_)
- Improve python discovery mechanism:

  - do not fail if there are executables that fail to query (e.g. for not having execute access to it) on the ``PATH``,
  - beside the prefix folder also try with the platform dependent binary folder within that,

  by :user:`gaborbernat`. (`#1545 <https://github.com/pypa/virtualenv/issues/1545>`_)
- When copying (either files or trees) do not copy the permission bits, last access time, last modification time, and
  flags as access to these might be forbidden (for example in case of the macOs Framework Python) and these are not needed
  for the user to use the virtual environment - by :user:`gaborbernat`. (`#1561 <https://github.com/pypa/virtualenv/issues/1561>`_)
- While discovering a python executables interpreters that cannot be queried are now displayed with info level rather
  than warning, so now they're no longer shown by default (these can be just executables to which we don't have access
  or that are broken, don't warn if it's not the target Python we want) - by :user:`gaborbernat`. (`#1574 <https://github.com/pypa/virtualenv/issues/1574>`_)
- The ``app-data`` :option:`seeder` no longer symlinks the packages on UNIX and copies on Windows. Instead by default
  always copies, however now has the :option:`symlink-app-data` flag allowing users to request this less robust but faster
  method - by :user:`gaborbernat`. (`#1575 <https://github.com/pypa/virtualenv/issues/1575>`_)

----------------------

Features - 20.0.0b2
~~~~~~~~~~~~~~~~~~~
- Improve base executable discovery mechanism:

  - print at debug level why we refuse some candidates,
  - when no candidates match exactly, instead of hard failing fallback to the closest match where the priority of
    matching attributes is: python implementation, major version, minor version, architecture, patch version,
    release level and serial (this is to facilitate things to still work when the OS upgrade replace/upgrades the system
    python with a never version, than what the virtualenv host python was created with),
  - always resolve system_executable information during the interpreter discovery, and the discovered environment is the
    system interpreter instead of the venv/virtualenv (this happened before lazily the first time we accessed, and caused
    reporting that the created virtual environment is of type of the virtualenv host python version, instead of the
    system pythons version - these two can differ if the OS upgraded the system python underneath and the virtualenv
    host was created via copy),

- Generate ``bash`` and ``fish`` activators on Windows too (as these can be available with git bash, cygwin or mysys2)
  - by :user:`gaborbernat`. (`#1527 <https://github.com/pypa/virtualenv/issues/1527>`_)
- Upgrade the bundled ``wheel`` package from ``0.34.0`` to ``0.34.2`` - by :user:`gaborbernat`. (`#1531 <https://github.com/pypa/virtualenv/issues/1531>`_)

Bugfixes - 20.0.0b2
~~~~~~~~~~~~~~~~~~~
- Bash activation script should have no extensions instead of ``.sh`` (this fixes the :pypi:`virtualenvwrapper`
  integration) - by :user:`gaborbernat`. (`#1508 <https://github.com/pypa/virtualenv/issues/1508>`_)
- Show less information when we run with a single verbosity (``-v``):

  - no longer shows accepted interpreters information (as the last proposed one is always the accepted one),
  - do not display the ``str_spec`` attribute for ``PythonSpec`` as these can be deduced from the other attributes,
  - for the ``app-data`` seeder do not show the type of lock, only the path to the app data directory,

  By :user:`gaborbernat`. (`#1510 <https://github.com/pypa/virtualenv/issues/1510>`_)
- Fixed cannot discover a python interpreter that has already been discovered under a different path (such is the case
  when we have multiple symlinks to the same interpreter) - by :user:`gaborbernat`. (`#1512 <https://github.com/pypa/virtualenv/issues/1512>`_)
- Support relative paths for ``-p`` - by :user:`gaborbernat`. (`#1514 <https://github.com/pypa/virtualenv/issues/1514>`_)
- Creating virtual environments in parallel fail with cannot acquire lock within app data - by :user:`gaborbernat`. (`#1516 <https://github.com/pypa/virtualenv/issues/1516>`_)
- pth files were not processed under Debian CPython2 interpreters - by :user:`gaborbernat`. (`#1517 <https://github.com/pypa/virtualenv/issues/1517>`_)
- Fix prompt not displayed correctly with upcoming fish 3.10 due to us not preserving ``$pipestatus`` - by
  :user:`krobelus`. (`#1530 <https://github.com/pypa/virtualenv/issues/1530>`_)
- Stable order within ``pyenv.cfg`` and add ``include-system-site-packages`` only for creators that reference a global
  Python - by user:`gaborbernat`. (`#1535 <https://github.com/pypa/virtualenv/issues/1535>`_)

Improved Documentation - 20.0.0b2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Create the first iteration of the new documentation - by :user:`gaborbernat`. (`#1465 <https://github.com/pypa/virtualenv/issues/1465>`_)
- Project readme is now of type MarkDown instead of reStructuredText - by :user:`gaborbernat`. (`#1531 <https://github.com/pypa/virtualenv/issues/1531>`_)


v20.0.0b1 (2020-01-28)
----------------------

* First public release of the rewrite. Everything is brand new and just added.
* ``--download`` defaults to ``False``

.. warning::

   The current virtualenv is the second iteration of implementation. From version ``0.8`` all the way to ``16.7.9``
   we numbered the first iteration. Version ``20.0.0b1`` is a complete rewrite of the package, and as such this release
   history starts from there. The old changelog is still available in the
   `legacy branch documentation <https://virtualenv.pypa.io/en/legacy/changes.html>`_.
