The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
LWG 3714
( P2711R1 ) 		C++20 the multi-parameter constructor was not explicit made explicit
P2325R3 C++20 if Pred is not default_initializable , the default constructor
constructs a take_while_view which does not contain an Pred 		the take_while_view is also
not default_initializable
