+        Add support for Java 8 Temporal types.  Date/time fields will now
+        accept as input most Temporal types (e.g. LocalDate, LocalTime,
+        LocalDateTime, etc).  Additionally, date/time fields can optionally be
+        changed to output LocalDateTime instead of Date.  This behavior is
+        configurable on a per-Database basis by setting the DateTimeType for
+        the database.  All Date based APIs now have a parallel LocalDateTime
+        API.  Note that only one of those will work depending on how
+        the Database is configured.  The legacy Date support will be the
+        default initially, but is deprecated and may be removed in the future.
