 +Core and Builtins
 +-----------------
 +
 +- Issue #23722: The __class__ cell used by zero-argument super() is now
 +  initialized from type.__new__ rather than __build_class__, so class methods
 +  relying on that will now work correctly when called from metaclass methods
 +  during class creation. Patch by Martin Teichmann.
 +
 +- Issue #25221: Fix corrupted result from PyLong_FromLong(0) when Python
 +  is compiled with NSMALLPOSINTS = 0.

 +- Issue #27080: Implement formatting support for PEP 515.  Initial patch
 +  by Chris Angelico.
 +
 +- Issue #27199: In tarfile, expose copyfileobj bufsize to improve throughput.
 +  Patch by Jason Fried.
 +
 +- Issue #27948: In f-strings, only allow backslashes inside the braces
 +  (where the expressions are).  This is a breaking change from the 3.6
 +  alpha releases, where backslashes are allowed anywhere in an
 +  f-string.  Also, require that expressions inside f-strings be
 +  enclosed within literal braces, and not escapes like
 +  f'\x7b"hi"\x7d'.
 +
 +- Issue #28046: Remove platform-specific directories from sys.path.
 +
 +- Issue #28071: Add early-out for differencing from an empty set.
