"Python 3.14 is here! Christopher Trudeau returns to discuss the new version with Real Python team member Bartosz Zaczyński. This year, Bartosz coordinated the series of preview articles with members of the Real Python team and wrote the showcase tutorial, "Python 3.14: Cool New Features for You to Try." Christopher's video course, "What's New in Python 3.14", covers the topics from the article and shows the new features in action."

Python 3.14 adds an upgraded interactive REPL, template string enhancements, lazily evaluated annotations, and improved subinterpreter support for isolation and concurrency. The release includes three asyncio changes that refine asynchronous APIs and behavior. Performance comparisons examine JIT and free-threaded mode impacts and provide compatibility heat maps for common libraries. PEP 810 proposes explicit lazy imports while third-party libraries already offer lazy import patterns. Educational resources include video courses, tutorials, and quizzes, and tooling such as a free-threaded compatibility checker assists migration, testing, and adoption of new features across ecosystems.
