+## Changes in Boost 1.91.0
+
+* Under {cpp}20, described nested enums now work when the enclosing class is still incomplete. (Thanks to Julien Blanc.)
+* Made `enum_to_string` constexpr. (Thanks to Julien Blanc.)
+
+## Changes in Boost 1.84.0
+
+* Added an overload of `enum_from_string` that takes a string view, to avoid
+  the need for null termination.

+The second overload only participates in overload resolution when `S` is a

+are recognized by the presence of nested `value_type` and `traits_type` typedefs
