+*** New command 'isearch-emoji-by-name'.
+It is bound to 'C-x 8 e RET' during an incremental search.  The
+command accepts the CLDR short name of an Emoji (for example, "smiling
+face" or "heart with arrow"), with minibuffer completion, and inserts
+the Emoji character into the search string.
+
 ** New minor mode 'glyphless-display-mode'.
 This allows an easy way to toggle seeing all glyphless characters in
 the current buffer.
