  <summary>Changelog</summary>
  
  
   ### 2.12.0
   ```
   -------------------

* Added coverage&#39;s `toml` extra to install requirements in setup.py.
  Contributed by Christian Riedel in `410 &lt;https://github.com/pytest-dev/pytest-cov/pull/410&gt;`_.
* 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 &lt;https://github.com/pytest-dev/pytest-cov/pull/467&gt;`_.
* Fixed *commits since* badge.
  Contributed by Terence Honles in `470 &lt;https://github.com/pytest-dev/pytest-cov/pull/470&gt;`_.
   ```
   
  
  
   ### 2.11.1
   ```
   -------------------

* Fixed support for newer setuptools (v42+).
  Contributed by Michał Górny in `451 &lt;https://github.com/pytest-dev/pytest-cov/pull/451&gt;`_.
   ```
   
  
  
   ### 2.11.0
   ```
   -------------------

* Bumped minimum coverage requirement to 5.2.1. This prevents reporting issues.
  Contributed by Mateus Berardo de Souza Terra in `433 &lt;https://github.com/pytest-dev/pytest-cov/pull/433&gt;`_.
* Improved sample projects (from the `examples &lt;https://github.com/pytest-dev/pytest-cov/tree/master/examples&gt;`_
  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 &lt;https://github.com/pytest-dev/pytest-cov/pull/435&gt;`_.
* Removed the empty `console_scripts` entrypoint that confused some Gentoo build script.
  I didn&#39;t ask why it was so broken cause I didn&#39;t want to ruin my day.
  Contributed by Michał Górny in `434 &lt;https://github.com/pytest-dev/pytest-cov/pull/434&gt;`_.
* Fixed the missing `coverage context &lt;https://coverage.readthedocs.io/en/stable/contexts.html&gt;`_
  when using subprocesses.
  Contributed by Bernát Gábor in `443 &lt;https://github.com/pytest-dev/pytest-cov/pull/443&gt;`_.
* Updated the config section in the docs.
  Contributed by Pamela McA&#39;Nulty in `429 &lt;https://github.com/pytest-dev/pytest-cov/pull/429&gt;`_.
* Migrated CI to travis-ci.com (from .org).
