Hello, three dot fourteen dot zero alpha four!

https://www.python.org/downloads/release/python-3140a4/

This is an early developer preview of Python 3.14.

Python 3.14 is still in development. This release, 3.14.0a4, is the fourth
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
* PEP 761: Python 3.14 and onwards no longer provides PGP signatures for
release artifacts. Instead, Sigstore is recommended for verifiers.
* Improved error messages
* Removals of old deprecations, and new deprecations, many scheduled for
removal from Python 3.16
* 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 3.14.0a5, currently scheduled
for 2025-02-11.

More resources:

* Online documentation: https://docs.python.org/3.14/
* PEP 745, 3.14 Release Schedule: https://peps.python.org/pep-0745/
* Report bugs at https://github.com/python/cpython/issues
* Help fund Python and its community: https://www.python.org/psf/donations/

And now for something completely different

In Python, you can use Greek letters as constants. For example:

```
from math import pi as π

def circumference(radius: float) -> float:
    return 2 * π * radius

print(circumference(6378.137))  # 40075.016685578485
```

Enjoy the new release.

Thanks to all of the many volunteers who help make Python Development and
these releases possible! Please consider supporting our efforts by
volunteering yourself or through organisation contributions to the Python
Software Foundation.

Regards from a slushy, slippery Helsinki,

Your release team,
