• Fix: adapt to pypy3.9’s decorator tracing behavior. It now traces function decorators like CPython 3.8: both the @-line and the def-line are traced. Fixes issue 1326.
• Debug: added pybehave to the list of Diagnostics: coverage debug and --debug options.
• Fix: show an intelligible error message if --concurrency=multiprocessing is used without a configuration file. Closes issue 1320.
