PyCharm 2017.1, is out! Faster debugger, better unit testing, and more. In PyCharm 2017.1:

• The Python debugger got forty times faster for Python 3.6 projects, and up to two times faster for older versions of Python
• We’ve added support for the six compatibility library
• Unit test runners for Python have been rebuilt from the ground up: you can now run any test configuration with PyCharm
• Are you a full stack developer? We’ve improved our JavaScript unit testing: gutter icons indicating whether a test passed and support for Jest, Facebook’s JS testing framework (only available in PyCharm Professional edition)
• Zero-latency typing is now on by default: typing latencies for PyCharm 2017.1 are lower than those for Sublime Text and Emacs
• Support for native Docker for Mac – no more need to use SOCAT! (only available in PyCharm Professional edition)
