Some highlights:

  • Improved performance when running Python subprocesses like Pytest, Flake8, and MyPy, thanks to Pex's new venv mode. This shaved off around 1 second for test runs in benchmarks!
  • ./pants tailor goal, which will auto-generate BUILD files for you. See Adopting Pants in existing repositories.
  • Support for specifying file:// URLs for downloaded tools like Pex and Protoc.
  • More robust remote caching support. The client should be more stable and should avoid performance slowdowns thanks to some new optimizations. See Remote Execution.
