  - Issue #25182: The stdprinter (used as sys.stderr before the io module is
    imported at startup) now uses the backslashreplace error handler.
  
 -- Issue #24891: Fix a race condition at Python startup if the file descriptor
 -  of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
 -  sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
 -  to None if the creation of the object failed, instead of raising an OSError
 -  exception. Initial patch written by Marco Paolini.
 -
 -- Issue #21167: NAN operations are now handled correctly when python is
 -  compiled with ICC even if -fp-model strict is not specified.
 -
 -- Issue #4395: Better testing and documentation of binary operators.
 -  Patch by Martin Panter.
 -
 -- Issue #24467: Fixed possible buffer over-read in bytearray. The bytearray
 -  object now always allocates place for trailing null byte and it's buffer now
 -  is always null-terminated.
 -
 -- Issue #24115: Update uses of PyObject_IsTrue(), PyObject_Not(),
 -  PyObject_IsInstance(), PyObject_RichCompareBool() and _PyDict_Contains()
 -  to check for and handle errors correctly.
 -
 -- Issue #24257: Fixed system error in the comparison of faked
 -  types.SimpleNamespace.
 -
 -- Issue #22939: Fixed integer overflow in iterator object.  Patch by
 -  Clement Rouault.
 -
 -- Issue #23985: Fix a possible buffer overrun when deleting a slice from
 -  the front of a bytearray and then appending some other bytes data.
 -
 -- Issue #24102: Fixed exception type checking in standard error handlers.
 -
 -- Issue #23757: PySequence_Tuple() incorrectly called the concrete list API
 -  when the data was a list subclass.
 -
 -- Issue #24407: Fix crash when dict is mutated while being updated.
 -
 -- Issue #24096: Make warnings.warn_explicit more robust against mutation of the
 -  warnings.filters list.
 -
 -- Issue #23996: Avoid a crash when a delegated generator raises an
 -  unnormalized StopIteration exception.  Patch by Stefan Behnel.
 -
 -- Issue #24022: Fix tokenizer crash when processing undecodable source code.
 +- Issue #25131: Make the line number and column offset of set/dict literals and
 +  comprehensions correspond to the opening brace.
  
 -- Issue #23309: Avoid a deadlock at shutdown if a daemon thread is aborted
 -  while it is holding a lock to a buffered I/O object, and the main thread
 -  tries to use the same I/O object (typically stdout or stderr).  A fatal
 -  error is emitted instead.
 +- Issue #25150: Hide the private _Py_atomic_xxx symbols from the public
 +  Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
 +  becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.
  
 -- Issue #22977: Fixed formatting Windows error messages on Wine.
 -  Patch by Martin Panter.
