 +
 +Core and Builtins
 +-----------------
 +
 +- Issue #23722: The __class__ cell used by zero-argument super() is now

 +  is compiled with NSMALLPOSINTS = 0.

 +
 +- 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.
