GH-126910: Allow most native profilers and debuggers to unwind through JIT frames (GH-143548) 2026-03-25 02:09:35 +08:00

gh-128341: Use _Py_ABI_SLOT in stdlib modules (#145770) 
Rename from _Py_INTERNAL_ABI_SLOT to _Py_ABI_SLOT
and define the macro using _PyABIInfo_DEFAULT.

Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.

_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.

gh-108907: ctypes: Document _type_ codes (GH-145837) 
Add `_SimpleCData._type_` docs.

Add type codes to the summary table.

Cross-link `struct`, `array`, and `ctypes`; throw in `numpy` too.
(Anyone wanting to add a code should be aware of those.)

Add `py_object`, and `VARIANT_BOOL` for completeness.

gh-145264: Do not ignore excess Base64 data after the first padded quad (GH-145267) 
Base64 decoder (see binascii.a2b_base64(), base64.b64decode(), etc)
no longer ignores excess data after the first padded quad in non-strict
(default) mode.  Instead, in conformance with RFC 4648, it ignores the
pad character, "=", if it is present before the end of the encoded data.

* Fix _Py_atomic_store_uint_release in pyatomic_msc.h to use __stlr32

* Add missing _Py_atomic_store_uint_release to pyatomic_gcc.h.

* Fix pseudo-code comment for _Py_atomic_store_ptr_release in
  pyatomic.h.
