=======
|
||||
|
||||
* The abstract base classes in :mod:`collections.abc` no longer are
|
||||
exposed in the regular :mod:`collections` module. This will help
|
||||
create a clearer distinction between the concrete classes and the abstract
|
||||
base classes.
|
||||
|
||||
* The undocumented ``sys.callstats()`` function has been removed. Since Python
|
||||
3.7, it was deprecated and always returned :const:`None`. It required a special
|
||||
build option ``CALL_PROFILE`` which was already removed in Python 3.7.
