Changelog

2.12.0

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

* Added coverage's `toml` extra to install requirements in setup.py.
Contributed by Christian Riedel in `410 <https://github.com/pytest-dev/pytest-cov/pull/410>`_.
* Fixed ``pytest_cov.__version__`` to have the right value (string with version instead of a string
including ``__version__ =``).
* Fixed license classifier in ``setup.py``.
Contributed by Chris Sreesangkom in `467 <https://github.com/pytest-dev/pytest-cov/pull/467>`_.
* Fixed *commits since* badge.
Contributed by Terence Honles in `470 <https://github.com/pytest-dev/pytest-cov/pull/470>`_.

2.11.1

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

* Fixed support for newer setuptools (v42+).
Contributed by Michał Górny in `451 <https://github.com/pytest-dev/pytest-cov/pull/451>`_.

2.11.0

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

* Bumped minimum coverage requirement to 5.2.1. This prevents reporting issues.
Contributed by Mateus Berardo de Souza Terra in `433 <https://github.com/pytest-dev/pytest-cov/pull/433>`_.
* Improved sample projects (from the `examples <https://github.com/pytest-dev/pytest-cov/tree/master/examples>`_
directory) to support running `tox -e pyXY`. Now the example configures a suffixed coverage data file,
and that makes the cleanup environment unnecessary.
Contributed by Ganden Schaffner in `435 <https://github.com/pytest-dev/pytest-cov/pull/435>`_.
* Removed the empty `console_scripts` entrypoint that confused some Gentoo build script.
I didn't ask why it was so broken cause I didn't want to ruin my day.
Contributed by Michał Górny in `434 <https://github.com/pytest-dev/pytest-cov/pull/434>`_.
* Fixed the missing `coverage context <https://coverage.readthedocs.io/en/stable/contexts.html>`_
when using subprocesses.
Contributed by Bernát Gábor in `443 <https://github.com/pytest-dev/pytest-cov/pull/443>`_.
* Updated the config section in the docs.
Contributed by Pamela McA'Nulty in `429 <https://github.com/pytest-dev/pytest-cov/pull/429>`_.
* Migrated CI to travis-ci.com (from .org).

2.10.1

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

* Support for ``pytest-xdist`` 2.0, which breaks compatibility with ``pytest-xdist`` before 1.22.3 (from 2017).
Contributed by Zac Hatfield-Dodds in `412 <https://github.com/pytest-dev/pytest-cov/pull/412>`_.
* Fixed the ``LocalPath has no attribute startswith`` failure that occurred when using the ``pytester`` plugin
in inline mode.

2.10.0

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

* Improved the ``--no-cov`` warning. Now it's only shown if ``--no-cov`` is present before ``--cov``.
* Removed legacy pytest support. Changed ``setup.py`` so that ``pytest>=4.6`` is required.

2.9.0

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

* Fixed ``RemovedInPytest4Warning`` when using Pytest 3.10.
Contributed by Michael Manganiello in `354 <https://github.com/pytest-dev/pytest-cov/pull/354>`_.
* Made pytest startup faster when plugin not active by lazy-importing.
Contributed by Anders Hovmöller in `339 <https://github.com/pytest-dev/pytest-cov/pull/339>`_.
* Various CI improvements.
Contributed by Daniel Hahler in `363 <https://github.com/pytest-dev/pytest-cov/pull/>`_ and
`364 <https://github.com/pytest-dev/pytest-cov/pull/364>`_.
* Various Python support updates (drop EOL 3.4, test against 3.8 final).
Contributed by Hugo van Kemenade in
`336 <https://github.com/pytest-dev/pytest-cov/pull/336>`_ and
`367 <https://github.com/pytest-dev/pytest-cov/pull/367>`_.
* Changed ``--cov-append`` to always enable ``data_suffix`` (a coverage setting).
Contributed by Harm Geerts in
`387 <https://github.com/pytest-dev/pytest-cov/pull/387>`_.
* Changed ``--cov-append`` to handle loading previous data better
(fixes various path aliasing issues).
* Various other testing improvements, github issue templates, example updates.
* Fixed internal failures that are caused by tests that change the current working directory by
ensuring a consistent working directory when coverage is called.
See `306 <https://github.com/pytest-dev/pytest-cov/issues/306>`_ and
`coveragepy881 <https://github.com/nedbat/coveragepy/issues/881>`_

2.8.1

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

* Fixed `348 <https://github.com/pytest-dev/pytest-cov/issues/348>`_ -
regression when only certain reports (html or xml) are used then ``--cov-fail-under`` always fails.

2.8.0

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

* Fixed ``RecursionError`` that can occur when using
`cleanup_on_signal <https://pytest-cov.readthedocs.io/en/latest/subprocess-support.html#if-you-got-custom-signal-handling>`__ or
`cleanup_on_sigterm <https://pytest-cov.readthedocs.io/en/latest/subprocess-support.html#if-you-got-custom-signal-handling>`__.
See: `294 <https://github.com/pytest-dev/pytest-cov/issues/294>`_.
The 2.7.x releases of pytest-cov should be considered broken regarding aforementioned cleanup API.
* Added compatibility with future xdist release that deprecates some internals
(match pytest-xdist master/worker terminology).
Contributed by Thomas Grainger in `321 <https://github.com/pytest-dev/pytest-cov/pull/321>`_
* Fixed breakage that occurs when multiple reporting options are used.
Contributed by Thomas Grainger in `338 <https://github.com/pytest-dev/pytest-cov/pull/338>`_.
* Changed internals to use a stub instead of ``os.devnull``.
Contributed by Thomas Grainger in `332 <https://github.com/pytest-dev/pytest-cov/pull/332>`_.
* Added support for Coverage 5.0.
Contributed by Ned Batchelder in `319 <https://github.com/pytest-dev/pytest-cov/pull/319>`_.
* Added support for float values in ``--cov-fail-under``.
Contributed by Martín Gaitán in `311 <https://github.com/pytest-dev/pytest-cov/pull/311>`_.
* Various documentation fixes. Contributed by
