Full Changelog: PyCQA/isort@9.0.0...9.0.1

9.0.0

isort 9.0.0 is the result of several alpha and beta releases, as well as a small number of fixes added after the last beta. For release notes for the individual alphas and betas we would like to refer to:

• 9.0.0a2
• 9.0.0a3
• 9.0.0b1
• 9.0.0b2
• 9.0.0b5

Skipped version numbers are the result of changes to our release infrastructure that broke while creating the actual releases.

Please find below the full release notes for version 9.0.0, the newest release of isort after version 8.0.1.

---

isort 9.0.0 contains some significant changes and improvements. Most notably there is now support for Python 3.15 and its lazy imports and we have included several performance improvements as well as providing mypyc compiled wheels for all major platforms and supported versions of Python. In our own tests we saw speeds ups of more than 2x and 3x times, but this is highly dependent on the codebase isort needs to inspect.

The full list of changes is as follows:
