What’s new

Improved @dataclass support

Data classes are a Python 3.7 feature that many developers are looking forward to. As Python 3.7 isn’t final yet, some details were changed recently. After an update to the PEP, we’ve made improvements to our support:

  • The hash parameter was changed to unsafe_hash. This parameter forces @dataclass to generate the __hash__ dunder method, even if the frozen parameter is set to False. In this case, the hash of your class can change if you make any changes to your class’s fields. A changing hash will break data structures that depend on it, like Dict. The Python core developers wanted to highlight that this should be done very carefully.
  • We now warn you if you use a parameter to generate a method which you’ve already defined.

Further Improvements

  • Pip 10.0 is now supported. A compatibility issue with IPython 6.3.0 was resolved.
  • Matplotlib plots are now correctly shown for scripts executed with “Run in Python Console”.
  • Django or Flask is now installed if you create a new project of those types on a remote machine
  • And more: read the release notes for details
