LGTM with some suggestions.

small trivially copyable -> small, trivially copyable

I'd fold this in to the previous bullet.

 - -Wtautological-bitwise-compare is a new warning group.  This group has the
   current warning which diagnoses the tautological comparison of a bitwise
   operation and a constant. The group also has the new warning which diagnoses
   when a bitwise-or with a non-negative value is converted to a bool, since
   that bool will always be true.
 - -Wbitwise-conditional-parentheses will warn on operator precedence issues
   when mixing bitwise-and (&) and bitwise-or (|) operator with the
   conditional operator (?:).
+- -Wrange-loop-analysis got several improvements. It no longer warns about a
+  copy being made when the result is bound to an rvalue reference. It no longer
+  warns when an object of a small trivially copyable type is copied. The
+  warning now offers fixits.
+- -Wrange-loop-analysis is now part of -Wall.

 * In both C and C++ (C17 ``6.5.6p8``, C++ ``[expr.add]``), pointer arithmetic is
   only permitted within arrays. In particular, the behavior of a program is not
   defined if it adds a non-zero offset (or in C, any offset) to a null pointer,
   or if it forms a null pointer by subtracting an integer from a non-null
