Improved in This Version

The debugger’s on-demand variable loading policy for NumPy arrays and Pandas DataFrames


When the on-demand variable loading policy is enabled in the debug mode, PyCharm doesn’t load NumPy arrays and Pandas DataFrames values by default. Previously, loading all the values caused severe slowdowns in case of large datasets. You can load the values manually from the debugger’s variables view when needed by simply clicking “Show value”.

File encoding specification inspection for Python 3


In PyCharm 2018.3.3, we’ve added the option to enable the “No encoding specified for a file” inspection for Python 3. This option is useful for those who work on Python 2/3 compatible code.

Further improvements

  • A fix for an extra file created when moving a class into another module
  • Several Docker and Docker Compose support fixes
  • Fixes for embedded terminal
  • Many fixes coming from WebStorm and IntelliJ IDEA – see the release notes for details
