gh-119132: Remove "experimental" tag from the CPython free-threading.#135550

corona10 · 2025-06-15T22:04:25Z

See: https://discuss.python.org/t/pep-779-criteria-for-supported-status-for-free-threaded-python/84319/123

Issue: Python -VV should display whether the build is default build or free-threading. #119132

…ading build

hugovk · 2025-06-15T22:12:40Z

And remove from docs here:

cpython/Doc/howto/free-threading-python.rst

Lines 45 to 46 in 60181f4

 To check if the current interpreter supports free-threading, :option:`python -VV <-V>` 
 and :data:`sys.version` contain "experimental free-threading build". 

This should also have a What's New entry about the PEP. And NEWS as well?

Nice catch, I also add you as co-authors.

corona10 · 2025-06-15T22:26:53Z

Also changing autoconf too.

@hugovk https://docs.python.org/3.15/using/mac.html#installing-free-threaded-binaries

I think that we should update macOS installer and Windows installer too but I hope that it should be discussed with @ned-deily and @zooba

ZeroIntensity

These cases also need to be changed:

cpython/Doc/using/mac.rst

Line 86 in 60181f4

To also install support for the optional experimental free-threaded feature,

cpython/Doc/using/mac.rst

Line 271 in 60181f4

 Python |usemac_x_dot_y| that supports :pep:`703`, the experimental free-threading feature 

cpython/Doc/library/ctypes.rst

Line 885 in 60181f4

 In Python 3.13, the :term:`GIL` may be disabled on :term:`experimental free threaded <free threading>` builds. 

cpython/Doc/using/windows.rst

Line 694 in 60181f4

Pre-built distributions of the experimental free-threaded build are available

Doc/howto/free-threading-python.rst

Oh, oops, you beat me to it.

I'm on it. I'll have the Mac installer and doc page updated for 3.14.0b3.

Thank you!

The Windows installer undel Tools/msi is already deprecated, so let's just leave it.

If there are "experimental" tags anywhere in the PC/layout folder (particularly PC/layout/support/pymanager.py) then those should be updated to include version number checks to determine whether to include it or not (the scripts may be used to build/package older versions as well, where we want to keep the tag).

hugovk · 2025-06-16T14:27:23Z

If there are "experimental" tags anywhere in the PC/layout folder [...]

None found 👍
