|

|

- Issue #2394: implement more of the memoryview API, with the caveat that
|
||||
only one-dimensional contiguous buffers are supported and exercised right
|
||||
now. Slicing, slice assignment and comparison (equality and inequality)
|
||||
have been added. Also, the tolist() method has been implemented, but only
|
||||
for byte buffers. Endly, the API has been updated to return bytes objects
|
||||
wherever it used to return bytearrays.
|
||||
|
||||
- Issue #3560: clean up the new C PyMemoryView API so that naming is
|
||||
internally consistent; add macros PyMemoryView_GET_BASE() and
|
||||
PyMemoryView_GET_BUFFER() to access useful properties of a memory views
