Version 4.0b1 — 2015-08-02

• Coverage.py is now licensed under the Apache 2.0 license. See NOTICE.txt for details. Closes issue 313.
• The data storage has been completely revamped. The data file is now JSON-based instead of a pickle, closing issue 236. The CoverageData class is now a public supported documented API to the data file.
• A new configuration option, [run] note, lets you set a note that will be stored in the runs section of the data file. You can use this to annotate the data file with any information you like.
• Unrecognized configuration options will now print an error message and stop coverage.py. This should help prevent configuration mistakes from passing silently. Finishes issue 386.
• In parallel mode, coverage erase will now delete all of the data files, fixing issue 262.
• Coverage.py now accepts a directory name for coverage run and will run a __main__.py found there, just like Python will. Fixes issue 252. Thanks, Dmitry Trofimov.
• The XML report now includes a missing-branches attribute. Thanks, Steve Peak. This is not a part of the Cobertura DTD, so the XML report no longer references the DTD.
• Missing branches in the HTML report now have a bit more information in the right-hand annotations. Hopefully this will make their meaning clearer.
• All the reporting functions now behave the same if no data had been collected, exiting with a status code of 1. Fixed fail_under to be applied even when the report is empty. Thanks, Ionel Cristian Mărieș.
• Plugins are now initialized differently. Instead of looking for a class called Plugin, coverage.py looks for a function called coverage_init.
• A file-tracing plugin can now ask to have built-in Python reporting by returning “python” from its file_reporter() method.
• Code that was executed with exec would be mis-attributed to the file that called it. This is now fixed, closing issue 380.
• The ability to use item access on Coverage.config (introduced in 4.0a2) has been changed to a more explicit Coverage.get_option and Coverage.set_option API.
• The Coverage.use_cache method is no longer supported.
• The private method Coverage._harvest_data is now called Coverage.get_data, and returns the CoverageData containing the collected data.
• The project is consistently referred to as “coverage.py” throughout the code and the documentation, closing issue 275.
• Combining data files with an explicit configuration file was broken in 4.0a6, but now works again, closing issue 385.
• coverage combine now accepts files as well as directories.
• The speed is back to 3.7.1 levels, after having slowed down due to plugin support, finishing up issue 387.
