Python 3.13.0a5

Release Date: March 12, 2024

This is an early developer preview of Python 3.13

Major new features of the 3.13 series, compared to 3.12

Python 3.13 is still in development. This release, 3.13.0a5, is the fifth of six planned alpha releases.

Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process.

During the alpha phase, features may be added up until the start of the beta phase (2024-05-07) and, if necessary, may be modified or deleted up until the release candidate phase (2024-07-30). Please keep in mind that this is a preview release and its use is not recommended for production environments.

Many new features for Python 3.13 are still being planned and written. Work continues apace on both the work to remove the Global Interpeter Lock, and to improve Python performance. The most notable changes so far:

(Hey, fellow core developer, if a feature you find important is missing from this list, let Thomas know.)

The next pre-release of Python 3.13 will be 3.13.0a6, currently scheduled for 2024-04-09.
