+* Wording in the Bison-generated parsers has been changed slightly to
+  simplify translation.  In particular, the message "memory exhausted"
+  has replaced "parser stack overflow", as the old message was not
+  always accurate for modern Bison-generated parsers.
+
+* Destructors are now called when the parser aborts, for all symbols left
+  behind on the stack.  Also, the start symbol is now destroyed after a
+  successful parse.  In both cases, the behavior was formerly inconsistent.
+
+* The yytname array now contains the same contents that it did in 2.0,
+  undoing an incompatible and undocumented change made in 2.0a.
