Documentation

The free threading document for 3.14 describes 3.14 as a future release with expected behavior.

It should be reworded to describe how the final version of 3.14 actually behaves.

In the Immortalization section:

Because immortal objects are never deallocated, applications that create many objects of these types may see increased memory usage. This is expected to be addressed in the 3.14 release.

Additionally, numeric and string literals in the code as well as strings returned by sys.intern() are also immortalized. This behavior is expected to remain in the 3.14 free-threaded build.

In the Single-threaded performance section:

the specializing adaptive interpreter (PEP 659) is disabled in the free-threaded build. We expect to re-enable it in a thread-safe way in the 3.14 release.
