- gh-102947: Improve traceback when dataclasses.fields() is
called on a non-dataclass. Patch by Alex Waygood
- gh-102780: The asyncio.Timeout context manager now
works reliably even when performing cleanup due to task
cancellation. Previously it could raise a CancelledError
instead of an TimeoutError in such cases.
- gh-88965: typing: Fix a bug relating to substitution in .
Pacustom classes generic over a ParamSpec. Previously, if .
Pathe ParamSpec was substituted with a parameters list that .
Paitself contained a TypeVar, the TypeVar in the parameters .
Palist could not be subsequently substituted. This is now .

if HTTPError is initialized without a designated fp
parameter. Patch by Long Vo.

dataclasses.
- gh-101566: In zipfile, apply fix for extractall on the
underlying zipfile after being wrapped in Path.
- gh-101892: Callable iterators no longer raise SystemError
when the callable object exhausts the iterator but forgets
to either return a sentinel value or raise StopIteration.
- gh-97786: Fix potential undefined behaviour in corner cases
of floating-point-to-time conversions.
- gh-101517: Fixed bug where bdb looks up the source line
with linecache with a lineno=None, which causes it to fail
with an unhandled exception.

local variables.
- gh-96931: Fix incorrect results from
ssl.SSLSocket.shared_ciphers()

regardless of their ordering relative to a zip64 “extra.”
- gh-96127: inspect.signature was raising TypeError on
call with mock objects. Now it correctly returns (*args,
**kwargs) as infered signature.
- gh-95495: When built against OpenSSL 3.0, the ssl module
had a bug where it reported unauthenticated EOFs (i.e.
without close_notify) as a clean TLS-level EOF. It now
raises SSLEOFError, matching the behavior in previous
versions of OpenSSL. The options attribute on SSLContext
also no longer includes OP_IGNORE_UNEXPECTED_EOF by
default. This option may be set to specify the previous
OpenSSL 3.0 behavior.

Paul Ganssle.
- gh-89792: test_tools now copies up to 10x less source data
to a temporary directory during the freeze test by ignoring
git metadata and other artifacts. It also limits its python
build parallelism based on os.cpu_count instead of hard
coding it as 8 cores.
