+  - Optimize substitution algorithm (including person substitutions) to be
+    more performant when you have a large set of substitutions defined (PR #208)
+  - Add support for defining a global concatenation option when constructing
+    the RiveScript object. This will set the default concat mode when
+    parsing files that didn't define their own local mode (PR #209)
+  - Add API function `lastTriggers(username)` to retrieve the full set of
