Heads up! This is a very big release for Nox. Please read these release notes thoroughly and reach out to us on GitHub if you run into issues.
Breaking changes and other important notes:
- Nox is now published as "nox" on PyPI. This means that Nox is installed via
pip install nox
instead ofnox-automation
. Since the new release makes so many breaking changes, we won't be updating the oldnox-automation
package. - Nox's configuration file is now called
noxfile.py
instead ofnox.py
. - Nox no longer supports Python 2.7. You can still create and run Python 2.7 sessions, but Nox itself must be installed using Python 3.5+.
- Nox's behavior has been changed from declarative to imperative. Session actions now run immediately. Existing code to setup session virtualenv, such as
session.interpreter
will break! Please consult the documentation on how to use@nox.session(python=[...])
to configure virtualenvs for sessions. - Nox now uses calver for releases.
- Support for the legacy naming convention (for example,
session_tests
) has been removed.
Other changes:
- Update colorlog dependency range.
- Update installation command in contributing. (#101)
- Remove Python 2.x object inheritance. (#109)
- Fix python syntax error on docs. (#111)
- Show additional links on PyPI. (#108)
- Add contributors file. (#113)
- Run sphinx with -W option. (#115)
- Using
os.pathsep
instead of a hardcoded':'
. (#105) - Use a configuration file for readthedocs. (#107)
- Add 'py' alias for
nox.session(python=...)
. - Fix processing of numeric Python versions that specify a patch version.
- Use Black to format code.
- Support invoking Nox using
python -m nox
. - Produce better error message when sessions can't be found.
