+
+	The following substantive changes were made:
+
+	* Added a new [[#parse-comma-list]] algorithm.
+
+	The following editorial changes were made:
+
+	* Switched to consistently refer to "identifier",
+		rather than sometimes using the term "name".
+
+	* Explicitly named several of the pre-tokenizing processes,
+		and explicitly referred to them in the parsing entry points
+		(rather than relying on a blanket "do X at the start of these algorithms" statement).
