+Subject: [PATCH] [Workaround] Skip ident comparison to avoid crash on Python
+ 3.13+
+
+Python 3.13 introduced major internal changes to thread management as part of
+PEP 703 (GIL removal), including native thread handles and joinable threads.
+These changes modified how thread identifiers are defined and used in the
+standard library, breaking compatibility with Eventlet's monkey-patched
+threading model.
+
+The issue decribed in #1030 is related to the GIL and PEP 703 because
+Python 3.13 introduced internal thread handles and joinable threads to
+support the no-GIL mode, changing how thread identifiers are managed:
+instead of simple values, they are now internal native identifiers handled
+at the C level, tied to OS-level threads or new CPython thread structures.
+
+Since Eventlet is deeply tied to green threads and emulates standard threads
+using greenlet-based constructs, properly adapting to Python 3.13 would
+require a near-complete rewrite of its threading logic.
+
+As a temporary workaround, this commit skips the comparison of thread
+identifiers to avoid AttributeErrors and restore partial functionality under
+Python 3.13+.
+
+A full fix will need a deeper architectural review.
+
+Related to #1030

+fork() without execve()
+=======================
+
+``fork()`` is a way to make a clone of a process.
+Most subprocesses replace the child process with a new executable, wiping out all memory from the parent process.
+A ``fork()ed`` subprocess can choose not to do this, and preserve data from the parent process.
+(Technically this is ``fork()`` without ``execve()``.)
+
+This is a terrible idea, as it can cause deadlocks, memory corruption, and crashes.
+
+For backwards compatibility, Eventlet *tries* to work in this case, but this is very much not guaranteed and your program may suffer from deadlocks, memory corruption, and crashes.
+This is even more so when using the ``asyncio`` hub, as that requires even more questionable interventions to "work".
+
+This is not a problem with Eventlet.
+It's a fundamental problem with ``fork()`` applicable to pretty much every Python program.
+
+Below are some common reasons you might be using ``fork()`` without knowing it, and what you can do about it.
+
+``multiprocessing``
+------------------
+
+On Linux, on Python 3.13 earlier, the standard library ``multiprocessing`` library uses ``fork()`` by default.
+To fix this, switch to the ``"spawn"`` method (the default in Python 3.14 and later) as `documented here <https://docs.python.org/3.13/library/multiprocessing.html#contexts-and-start-methods>`.
+
+
+``oslo.service``
+----------------
+
+There are alternative ways of running services that do not use ``fork()``.
+See the documentation.

Unreleased
==========
+0.40.1
+======
+
+* [fix] "Fix" fork() so it "works" on Python 3.13, and "works" better on older Python versions (#1047)
+ * Behavior change: threads created by eventlet.green.threading.Thread and threading.Thead will be visible across both modules if monkey patching was used. Previously each module would only list threads created in that module.
+ * Bug fix: after fork(), greenlet threads are correctly listed in threading.enumerate() if monkey patching was used. You should not use fork()-without-execve().
+* [fix] Fix patching of removed URLopener class in Python 3.14 (#1053)
+* [fix] ReferenceError except while count rlock (#1042)
+* [fix] Replace deprecated datetime.utcfromtimestamp (#1050)
+* [fix][env] Remove duplicate steps (#1049)
+* [fix] Replace deprecated datetime.datetime.utcnow (#1046)
+
+0.40.0
+======
+
+* [fix] Fix ssl test when linking against openssl 3.5 (#1034)
+* Drop support Python 3.8 (#1021)
+* [doc] Various doc updates (#981, #1033)
+* [env] Drop PyPy support (#1035 #1037)
+
