Python 3.14, set for release later this year, introduces a revamped CPython interpreter that leverages a form of tail call optimization at the C level to accelerate bytecode dispatch—potentially boosting performance by up to 30%. Importantly, this change does not alter the Python language itself, meaning no modifications are required to existing Python code or C extension modules, and it maintains full compatibility with current CPython APIs and ABIs while keeping maintenance overhead minimal.

Python 3.14, due out later this yr, is about to obtain a brand new kind of interpreter that may increase efficiency by as much as 30% with no adjustments to present code.The CPython 3.14 change log describes the feature as “a brand new kind of interpreter primarily based on tail calls.” This description could also be just a little deceptive for individuals who don’t carefully comply with inner Python improvement work. “Tail calls” doesn’t imply that CPython, or the Python language, will now help tail call optimization. It refers to an optimization {that a} C compiler performs on the CPython code, which hurries up the best way the interpreter dispatches its bytecode directions.
No adjustments to present Python code are required, and C extension modules for CPython don’t have to be recompiled both, as there are not any adjustments to the CPython APIs or ABIs. Nor does the brand new interpreter add vital upkeep overhead to CPython, because it’s been carried out primarily by repurposing present code.
