Issue #13992 : The trashcan mechanism is now thread-safe. This eliminates

sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.
Note that the trashcan functions are part of the stable ABI, therefore
they have to be kept around for binary compatibility of extensions.

Issue #13992 : The trashcan mechanism is now thread-safe. This eliminates
...
sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.
Because of this change, a couple extension modules compiled for 3.2.4
(those which use the trashcan mechanism, despite it being undocumented)
will not be loadable by 3.2.3 and earlier. However, extension modules
compiled for 3.2.3 and earlier will be loadable by 3.2.4.

- Issue #10181 : New memoryview implementation fixes multiple ownership
...
and lifetime issues of dynamically allocated Py_buffer members (#9990 )
as well as crashes (#8305 , #7433 ). Many new features have been added
(See whatsnew/3.3), and the documentation has been updated extensively.
The ndarray test object from _testbuffer.c implements all aspects of
PEP-3118, so further development towards the complete implementation
of the PEP can proceed in a test-driven manner.
Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
and many ideas.
- Issue #12834 : Fix incorrect results of memoryview.tobytes() for
non-contiguous arrays.
- Issue #5231 : Introduce memoryview.cast() method that allows changing
format and shape without making a copy of the underlying memory.
