[diff.cpp14.expr]
Annex C (informative) Compatibility [diff]
C.4 C++ and ISO C++ 2014 [diff.cpp14]
C.4.3 [expr]: expressions [diff.cpp14.expr]
Affected subclauses: [expr.post.incr] and [expr.pre.incr]
Change: Remove increment operator with bool operand.
Rationale: Obsolete feature with occasionally surprising semantics.
Effect on original feature: A valid C++ 2014 expression utilizing the increment operator on a bool lvalue is ill-formed in this revision of C++.
Affected subclauses: [expr.new] and [expr.delete]
Change: Dynamic allocation mechanism for over-aligned types.
Rationale: Simplify use of over-aligned types.
Effect on original feature: In C++ 2014 code that uses a new-expression to allocate an object with an over-aligned class type, where that class has no allocation functions of its own,::operator new(std::size_t) is used to allocate the memory.
In this revision of C++,::operator new(std::size_t, std::align_val_t) is used instead.
