 ** Bug fixes
 
+*** Location of errors
+
+  In C++ parsers, out-of-bounds errors can happen when a rule with an empty
+  ride-hand side raises a syntax error.  The behavior of the default parser
+  (yacc.c) in such a condition was undefined.
+
+  Now all the parsers match the behavior of glr.c: @$ is used as the
+  location of the error.  This handles gracefully rules with and without
+  rhs.
+
+* Noteworthy changes in release 3.0.4 (2015-01-23) [stable]
+
+** Bug fixes
+
+*** C++ with Variants (lalr1.cc)
+
+  Fix a compiler warning when no %destructor use $$.
+
+*** Test suites
+
+  Several portability issues in tests were fixed.
+
+* Noteworthy changes in release 3.0.3 (2015-01-15) [stable]
+
+** Bug fixes
+
+*** C++ with Variants (lalr1.cc)
+
+  Problems with %destructor and '%define parse.assert' have been fixed.
+
+*** Named %union support (yacc.c, glr.c)
+
+  Bison 3.0 introduced a regression on named %union such as
+
+    %union foo { int ival; };
+
+  The possibility to use a name was introduced "for Yacc compatibility".
+  It is however not required by POSIX Yacc, and its usefulness is not clear.
+
+*** %define api.value.type union with %defines (yacc.c, glr.c)
+
+  The C parsers were broken when %defines was used together with "%define
+  api.value.type union".
+
 *** Redeclarations are reported in proper order
