- Security
- Replaced usage of tempfile.mktemp() with TemporaryDirectory
to avoid a potential race condition.
- Add auditing events to the marshal module, and stop raising
code.__init__ events for every unmarshalled code object.
Directly instantiated code objects will continue to raise
an event, and audit event handlers should inspect or
collect the raw marshal data. This reduces a significant
performance overhead when loading from .pyc files.
- Made the internal putcmd function in smtplib sanitize input
for presence of \r and \n characters to avoid (unlikely)
command injection.
- Core and Builtins
- Fixed pickling of range iterators that iterated for over
2**32 times.
- Fix a race in WeakKeyDictionary, WeakValueDictionary and
WeakSet when two threads attempt to commit the last pending
removal. This fixes asyncio.create_task and fixes a data
loss in asyncio.run where shutdown_asyncgens is not run
- Fixed a corner case bug where the result of
float.fromhex('0x.8p-1074') was rounded the wrong way.
- Refine the syntax error for trailing commas in import
statements. Patch by Pablo Galindo.
- Restore behaviour of complex exponentiation with
integer-valued exponent of type float or complex.
- Correct the ast locations of f-strings with format specs
and repeated expressions. Patch by Pablo Galindo
- Use new trashcan macros (Py_TRASHCAN_BEGIN/END) in
frameobject.c instead of the old ones
