In the ideal case, binaries built this way will continue working all the way through to the last pre-freeze release. However, if the project is affected by a change in the full CPython C ABI during the pre-freeze period, then it will be necessary to publish a maintenance update that re...

In general, these tools fall into one of two categories: Shallow parsers don't try to understand the full syntax of Python, but instead scan the source code for specific known patterns. IDEs, such as Visual Studio Code, Emacs and TextMate, tend to fall in this category, since frequently ...
