6.1.0

Added

• Support using VCS URLs in requirements files.

Fixed

• Building wheels for packages like zope-event that normalise the project name using dots instead of underscores is no longer broken.

6.0.0

Added

• Python 3.10 and 3.11 are now supported.

Changed

• Improved performance of checking for already built packages.

Removed

• Dropped support for running tests via setup.py test.
  The mechanism is considered deprecated by upstream and removing it allows us to drop a dependency.
• Python 3.6 is no longer supported. It likely still works but we will no longer run CI against it.

5.1.0

Added

• Provide compatibility with pip 21.3 and above which drops the --build-directory option. Pip has been using a temporary directory for builds since version 1.2 so manual handling of this directory should not be necessary anymore.

v5.0.0

Fixed

• Remove dependency on the internal wheel API.
  This blocked the use of wheel versions >= 0.32.

Removed

• Python 2 is no longer supported.
• Python 3.5 is no longer supported.
