Wing Python IDE

The Intelligent Development Environment for Python

What's New in Wing 9.1

Wing 9.1 adds auto-import and import management, collects and displays code coverage for unit tests, uses coverage data to invalidate test results when code is edited, adds support for Python 3.11, reduces debugger overhead in Python 3.7+, speeds up running unit tests, streamlines configuration of light and dark theming, adds two light display themes, and makes improvements to New Project for Docker and Django, auto-invocation, multi-threaded debugging, code analysis, & more.

Import Management

Wing 9.1 adds the ability to auto-enter imports from the auto-completer, eliminating the need to move up and down in a file to add imports while writing new code. The new Imports tool makes it easy to find and remove imports that are unused anywhere in your code.

Code Coverage

Wing 9.1 added the ability to track and display code coverage for unit tests, so that you can see how well your tests are exercising your code. Coverage data is also used to determine which previously collected test results are invalidated by edits made to your code, so that tests affected by edits may be re-run sooner in the development process.

Faster Debugging and Unit Testing

Wing 9.1 reduces debugger overhead by about 20-50% in Python 3.7+. The exact amount of performance improvement you will see depends on the nature of the code that is being debugged and the Python version that you are using. Wing 9.1 also substantially speeds up running unit tests in projects with large numbers of unit tests and when tests produce a large amount of output.

Streamlined Light and Dark Theming

Wing 9.1 allows configuring a light and dark theme independently (on the first Preferences page) in order to make it easier to switch between light and dark modes. Two new light themes New Light and Faerie Storm have been added, and switching display modes should be faster and smoother visually.

Other Improvements
