[dependabot]

Changelog

Sourced from pytest-cov's changelog.

2.11.1 (2021-01-20)

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

2.11.0 (2021-01-18)

• 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/issues/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/issues/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/issues/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/issues/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/issues/429) <https://github.com/pytest-dev/pytest-cov/pull/429>_.
• Migrated CI to travis-ci.com (from .org).

2.10.1 (2020-08-14)

• 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/issues/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 (2020-06-12)

• 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 (2020-05-22)

• Fixed RemovedInPytest4Warning when using Pytest 3.10. Contributed by Michael Manganiello in [#354](https://github.com/pytest-dev/pytest-cov/issues/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/issues/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/issues/363) <https://github.com/pytest-dev/pytest-cov/pull/>_ and [#364](https://github.com/pytest-dev/pytest-cov/issues/364) <https://github.com/pytest-dev/pytest-cov/pull/364>_.
• Various Python support updates (drop EOL 3.4, test against 3.8 final).
