+      \item Preserve backwards compatibility with \cpkg{Rcpp} 0.10.* by
       allowing \code{RObject} extraction from vectors (or lists) of Rcpp
       objects
       \item Add missing default constructor to Reference class that was
       omitted in the header-only rewrite
-      \item Fixes re: the NA, NaN handling for the IndexHash class, as well
-      as the vector .sort() method. These fixes ensure that sugar functions
-      depending on IndexHash (unique, sort_unique, match) will now properly
-      handle NA and NaN values for numeric vectors.
-      \item DataFrame::nrows now more accurately mimics R's internal behavior
-      (checks the row.names attribute)
