According to the versionchanged note, the `strict` argument was removed in 3.3 and `policy` was added, but the name of the argument in the paragraph wasn't updated.

When runnint test_logging with --huntrleaks after commit
18fb1fb9, test_out_of_order fails
to raise ValueError due to the fact that the new test
test_out_of_order_with_dollar_style mutates the out_of_order
dictionary. Even if the test copies the dictionary first, the mutation
is done in a very deep level so the original one is also affected.

Fix test_cmd_line_script.test_nonexisting_script(): the test must not
rely on sys.executable, since main.c uses config->program which can
be different than sys.executable in many cases (for example, on macOS
when using the framework).

bpo-23554: Change echo server example class name from EchoServerClientProtocol to EchoServerProtocol (GH-9859)

python-gdb.py now handles errors on computing the line number
of a Python frame.

Changes:

* PyFrameObjectPtr.current_line_num() now catchs any Exception on
  calling addr2line(), instead of failing with a surprising "<class
  'TypeError'> 'FakeRepr' object is not subscriptable" error.
* All callers of current_line_num() now handle current_line_num()
  returning None.
* PyFrameObjectPtr.current_line() now also catchs IndexError on
  getting a line from the Python source file.

* fix dangling mention of key=str.lower in heapq doc

* Fix dangling mention of keyfunc example for sorted()

bpo-34844: logging.Formatter enhancement - Ensure style and format string matches in logging.Formatter  (GH-9703)

bytes and bytearray constructors converted unexpected exceptions
(e.g. MemoryError and KeyboardInterrupt) to TypeError.

Allow annotated global names in the module namespace after the symbol is
declared as global. Previously, only symbols annotated before they are declared
as global (i.e. inside a function) were allowed. This change allows symbols to be
declared as global before the annotation happens in the global scope.

* Add News entry for the change in multiprocessing.reduction.recvfds
made in GH-9613.

Methods find(), findtext() and findall() of xml.etree.ElementTree.Element
were not able to find chldren which are instances of Element subclasses.

A Windows build with _tkinter, tkinter, and idlelib
but without ctypes is unlikely but apparently possible.

Covered all special cases: bytes, tuple, list, differend
kinds of iterables and iterators.

bpo-22872: multiprocessing.Queue's put() and get() now raise ValueError if the queue is closed. (GH-9010)

Previously, put() and get() would raise AssertionError and OSError,
respectively.

With macOS framework builds, test case test_nonexisting_script in
test_nonexisting_script fails because the test case assumes that
the file name in sys.executable will appear in the error message.
For macOS framework builds, sys.executable is the file name of the
stub launcher and its file name bears no relationship to the file
name of the actual python executable.  For now, skip the test in
this case.

Replace "Availability: xxx" with ".. availability:: xxx" in the doc.

for the SHAKE algorithm in the hashlib module.

It was proposed to add an warning for http.server regarding security
issues. The wording was provided at bpo-26005 by @orsenthil

Unconditional forcing of ``CHECKED_HASH`` invalidation was introduced in
3.7.0 in bpo-29708.  The change is bad, as it unconditionally overrides
*invalidation_mode*, even if it was passed as an explicit argument to
``py_compile.compile()`` or ``compileall``.  An environment variable
should *never* override an explicit argument to a library function.
That change leads to multiple test failures if the ``SOURCE_DATE_EPOCH``
environment variable is set.

This changes ``py_compile.compile()`` to only look at
``SOURCE_DATE_EPOCH`` if no explicit *invalidation_mode* was specified.
I also made various relevant tests run with explicit control over the
value of ``SOURCE_DATE_EPOCH``.

While looking at this, I noticed that ``zipimport`` does not work
with hash-based .pycs _at all_, though I left the fixes for
subsequent commits.

:meth:`mimetypes.MimeTypes.guess_type` now accepts :term:`path-like object` in addition to url strings.

Tests involving sending signals to the semaphore_tracker will not fail anymore due to
the fact that running the test suite with -Werror propagates warnings as errors.

Fix a missing assertion when the semaphore_tracker is expected to die.
