In `urllib.request.url2pathname()`, if the authority resolves to the
current host, discard it. If an authority is present but resolves somewhere
else, then on Windows we return a UNC path (as before), and on other
platforms we raise `URLError`.
Affects `pathlib.Path.from_uri()` in the same way.

Make `warnings.catch_warnings()` use a context variable for holding
the warning filtering state if the `sys.flags.context_aware_warnings`
flag is set to true. This makes using the context manager thread-safe in
multi-threaded programs.
Add the `sys.flags.thread_inherit_context` flag. If true, starting a new
thread with `threading.Thread` will use a copy of the context
from the caller of `Thread.start()`.
Both these flags are set to true by default for the free-threaded build
and false for the default build.
Move the Python implementation of warnings.py into _py_warnings.py.
Make _contextvars a builtin module.

Non-tuple sequences are deprecated as argument for the "(items)" format unit
in PyArg_ParseTuple() and other argument parsing functions if items contains
format units which store borrowed buffer or reference (e.g. "s" and "O").
str and bytearray are no longer accepted as valid sequences.

* Add ZipFile.data_offset attribute
This attribute provides the offset to zip data from the start of the file, when available.
* Add blurb-it
* Try fixing class ref in NEWS
The `http.server` module now supports serving over HTTPS using the `http.server.HTTPSServer` class.
This functionality is also exposed by the command-line interface (`python -m http.server`) through the
`--tls-cert`, `--tls-key` and `--tls-password-file` options.
A new extension module, `_hmac`, now exposes the HACL* HMAC (formally verified) implementation.
The HACL* implementation is used as a fallback implementation when the OpenSSL implementation of HMAC
is not available or disabled. For now, only named hash algorithms are recognized and SIMD support provided
by HACL* for the BLAKE2 hash functions is not yet used.
It doesn't make sense to use a deprecation for evaluate_forward_ref,
as it is a new function in Python 3.14 and doesn't have compatibility
guarantees.
I considered making it throw an error if type_params it not passed and
there is no owner. However, I think this is too unfriendly for users. The
case where this param is really needed is fairly esoteric and I don't think
this case is worth the pain of forcing users to write "type_params=()".
Optimize `LOAD_FAST` opcodes into faster versions that load borrowed references onto the operand stack when we can prove that the lifetime of the local outlives the lifetime of the temporary that is loaded onto the stack.
