Python 3.14.0a7

Release Date: April 8, 2025

Here comes the final alpha! This means we have just four weeks until the first beta to get those last features into 3.14 before the feature freeze on 2025-05-06!

https://www.python.org/downloads/release/python-3140a7/

This is an early developer preview of Python 3.14

Major new features of the 3.14 series, compared to 3.13

Python 3.14 is still in development. This release, 3.14.0a7, is the last of seven 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 (2025-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2025-07-22). Please keep in mind that this is a preview release and its use is not recommended for production environments.

Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far:

  • PEP 649: deferred evaluation of annotations
  • PEP 741: Python configuration C API annotations
  • PEP 758: Allow except and except* expressions without parentheses
  • PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers.
  • PEP 765: disallow return/break/continue that exit a finally block
  • PEP 768: Safe external debugger interface for CPython
  • A new type of interpreter. For certain newer compilers, this interpreter provides significantly better performance. Opt-in for now, requires building from source.
  • UUID versions 6-8 are now supported by the uuid module, and generation of versions 3-5 and 8 are up to 40% faster.
  • Improved error messages
  • Python removals and deprecations
  • C API removals and deprecations
  • (Hey, fellow core developer, if a feature you find important is missing from this list, let Hugo know.)

The next pre-release of Python 3.14 will be the first beta, 3.14.0b1, currently scheduled for 2025-05-06. After this, no new features can be added but bug fixes and docs improvements are allowed -- and encouraged!
