Python 3.14.0 (final) is here!

[hugovk (Hugo van Kemenade)]

Python 3.14.0 is now available

Python Release Python 3.14.0

This is the stable release of Python 3.14.0

Python 3.14.0 is the newest major release of the Python programming language, and it contains many new features and optimisations compared to Python 3.13.

Major new features of the 3.14 series, compared to 3.13

Some of the major new features and changes in Python 3.14 are:

New features

• PEP 779: Free-threaded Python is officially supported
• PEP 649: The evaluation of annotations is now deferred, improving the semantics of using annotations.
• PEP 750: Template string literals (t-strings) for custom string processing, using the familiar syntax of f-strings.
• PEP 734: Multiple interpreters in the stdlib.
• PEP 784: A new module compression.zstd providing support for the Zstandard compression algorithm.
• PEP 758: except and except* expressions may now omit the brackets.
• Syntax highlighting in PyREPL, and support for color in unittest, argparse, json and calendar CLIs.
• PEP 768: A zero-overhead external debugger interface for CPython.
• UUID versions 6-8 are now supported by the uuid module, and generation of versions 3-5 are up to 40% faster.
• PEP 765: Disallow return/break/continue that exit a finally block.
• PEP 741: An improved C API for configuring Python.
• A new type of interpreter. For certain newer compilers, this interpreter provides significantly better performance. Opt-in for now, requires building from source.
• Improved error messages.
• Builtin implementation of HMAC with formally verified code from the HACL* project.
• A new command-line interface to inspect running Python processes using asynchronous tasks.
• The pdb module now supports remote attaching to a running Python process.

For more details on the changes to Python 3.14, see What’s new in Python 3.14.

Build changes

• PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers.
• Official macOS and Windows release binaries include an experimental JIT compiler.
• Official Android binary releases are now available.

Python install manager

The installer we offer for Windows is being replaced by our new install manager, which can be installed from the Windows Store or from its download page. See our documentation for more information. The JSON file available for download contains the list of all the installable packages available as part of this release, including file URLs and hashes, but is not required to install the latest release. The traditional installer will remain available throughout the 3.14 and 3.15 releases.

And now for something completely different

Edgar Allen Poe died on 7th October 1849.

As we all recall from 3.14.0a1, piphilology is the creation of mnemonics to help memorise the digits of π, and the number of letters in each word in a pi-poem (or “piem”) successively correspond to the digits of π.

In 1995, Mike Keith, an American mathematician and author of constrained writing, retold Poe’s The Raven as a 740-word piem. Here’s the first two stanzas of Near A Raven:

            Poe, E.
      Near a Raven

Midnights so dreary, tired and weary.
    Silently pondering volumes extolling all by-now obsolete lore.
During my rather long nap - the weirdest tap!
    An ominous vibrating sound disturbing my chamber’s antedoor.
        “This”, I whispered quietly, “I ignore”.

Perfectly, the intellect remembers: the ghostly fires, a glittering ember.
    Inflamed by lightning’s outbursts, windows cast penumbras upon this floor.
Sorrowful, as one mistreated, unhappy thoughts I heeded:
    That inimitable lesson in elegance - Lenore -
        Is delighting, exciting…nevermore.

Enjoy the new release

The online documentation has been updated such that docs.python.org/3/ now points to Python 3.14. Enjoy using the new release!

Core team: I’ve unlocked the 3.14 branch, you can start merging your backports for 3.14.1.

Try not to break everything! You can run buildbots on your PRs before merge, and click to “update branch” if it’s been a while since GitHub Actions ran.

Awesome! This is the version I’ve been looking forward to the most personally. There are so many exciting features I’m anticipating, like no-GIL / JIT / t-string / pdb / asyncio !

[JoBe]

Lovely, I’ve been looking forward to this day for quite some time.

I’m glad the release went as smoothly as it could have went.

[UltimateLobster (Nir Schulman)]

Finally Pie-thon is here !

Can’t wait to use the new features and installer!

The ci-images have been updated to include the final 3.14.0 release. From now until 3.15.0a1, they’ll also include those builds at git head, whenever the automation runs. For Pythons >= 3.13, you’ll get both the standard build and the free-threading builds (e.g. 3.14.0t).

Other visible changes include:

• Ubuntu 24.04 serves as the base OS
• pipx from Ubuntu is installed, rather than from PyPI
• mypy, codecov, and tox are no longer pip installed by default. The latest uv is still installed.

It looks like the new Python Install Manager on the Windows Store is still showing as Beta. Is that correct? Do we know when the final release will be available in the Store? I also note that the main Windows download link for 3.14 is still the traditional installer. You need to go to the “Downloads for Windows” page to see the new manager. Is that intentional?

PEP 773 doesn’t actually state a Python version when the new manager would become the official installer, but it felt like there was a pretty solid expectation (reinforced by the release announcement here) that it would be 3.14.

It’s coming today, there were some hiccups with Windows Server 2025 trying to install updates and blocking tests. See python/pymanager#178 for the fix.

[pf_moore (Paul Moore)]

Cool, I saw the issue notifications and assumed they were relevant , but I thought it might be worth checking here to get confirmation, and for visibility. Thanks.
