Changelog

Sourced from pytest-cov's changelog.

2.12.1 (2021-06-01)

• Changed the toml requirement to be always be directly required (instead of being required through a coverage extra). This fixes issues with pip-compile (pip-tools#1300). Contributed by Sorin Sbarnea in #472.
• Documented show_contexts. Contributed by Brian Rutledge in #473.

2.12.0 (2021-05-14)

• Added coverage's toml extra to install requirements in setup.py. Contributed by Christian Riedel in #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.
• Fixed commits since badge. Contributed by Terence Honles in #470.

2.11.1 (2021-01-20)

• Fixed support for newer setuptools (v42+). Contributed by Michał Górny in #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.
• Improved sample projects (from the 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.
• 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.
• Fixed the missing coverage context when using subprocesses. Contributed by Bernát Gábor in #443.
• Updated the config section in the docs. Contributed by Pamela McA'Nulty in #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.
• 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.
• Made pytest startup faster when plugin not active by lazy-importing. Contributed by Anders Hovmöller in #339.
• Various CI improvements. Contributed by Daniel Hahler in #363 and #364.
• Various Python support updates (drop EOL 3.4, test against 3.8 final). Contributed by Hugo van Kemenade in #336 and #367.
• Changed --cov-append to always enable data_suffix (a coverage setting). Contributed by Harm Geerts in #387.
• Changed --cov-append to handle loading previous data better (fixes various path aliasing issues).
