Python 3.13.0 alpha 2¶
- Core and Builtins:
- Don’t include comments in f-string debug expressions. Patch
by Pablo Galindo
- Slightly optimize the Tier 2 (uop) interpreter by only
loading oparg and operand when needed. Also double the
trace size limit again, to 512 this time.
- Change docstrings of __dict__ and __weakref__.
- Lower the max parser stack depth to 1000 under WASI debug
builds.
- When Python is built in debug mode, set the C recursion
limit to 500 instead of 1500. A debug build is likely built
with low optimization level which implies higher stack
memory usage than a release build. Patch by Victor Stinner.
- Enable translating unspecialized FOR_ITER to Tier 2.
- Make hashlib related modules thread-safe without the GIL
- Deprecate assignment to a function’s __code__ field when
the new code object is of a mismatched type (e.g., from a
generator to a plain function).
- Raise exception if frame.clear() is called on a suspended
frame.
- Implement native thread ids for GNU KFreeBSD.
- Use exponential backoff to reduce the number of failed tier
2 optimization attempts by over 99%.
- Joining a thread now ensures the underlying OS thread has
exited. This is required for safer fork() in multi-threaded
processes.
- Make sure that tier 2 traces are de-optimized if the code
is instrumented
