 Changes in version 2.1a:
 
+* %destructor vs. YYACCEPT, YYERROR, and YYABORT.
+  When the parsing/action is cut by the user using one of these
+  special actions, the stack is freed except the right-hand side
+  symbols of the current rule.
+
+* GLR, C++ LALR(1) parsers.
+  These parser skeletons are now distributed with the same special
+  license exception that the C LALR(1) parser skeleton has had since
+  Bison 1.24.  Hence the FSF imposes no copyright restriction on the
+  output of Bison when it is generating such parsers.
+
+* %expect, %expect-rr
+  Incorrect numbers of expected conflicts are now actual errors,
+  instead of warnings.
+
+* GLR, YACC parsers.
+  The %parse-params are available in the %destructor's (and the
+  experimental %printer's) as per the documentation.

 * Bison now warns if it finds a stray `$' or `@' in an action.
