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.

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'``.
