Python 3.15 Arrives, Dropping 3.10 and Embracing 3.11 Features
Python 3.15 launches with new Explicit Lazy Imports and marks the end of support for 3.10, allowing developers to adopt 3.11 features.
Python 3.15 has been officially released, as announced by Simon Willison on October 12, 2026. The release notes, curated by 3.14 and 3.15 release manager Hugo van Kemenade, detail the most notable changes for developers.
One of the headline features is Explicit Lazy Imports, introduced by PEP 810. This syntax lets developers defer module loading until the first use, improving startup time and memory usage. The new syntax looks like lazy import json and is documented in the official "What's new in Python 3.15" guide.
The update also signals a transition for open‑source maintainers: Python 3.10 is now unsupported, while Python 3.11’s enhancements become the baseline for future development. This shift encourages projects to adopt newer language features and performance improvements.
For those interested in exploring the full list of changes, the release page and the detailed "What's new" documentation are available on python.org.
Overall, Python 3.15 positions the language for continued growth, offering developers a clear path forward with modern import mechanics and a refreshed compatibility landscape.
