+*** Named %union support
+
+ 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
+
+ The yacc.c and glr.c parsers were broken when %defines was used
+ together with "%define api.value.type union".
+
+*** Redeclarations are reported in proper order
+
+ On
+
+ %token FOO "foo"
+ %printer {} "foo"
+ %printer {} FOO
+
+ bison used to report:
+
+ /tmp/foo.yy:2.10-11: error: %printer redeclaration for FOO
+ %printer {} "foo"
+ ^^
+ /tmp/foo.yy:3.10-11: previous declaration
+ %printer {} FOO
+ ^^
+
+ Now, the "previous" declaration is always the first one.
+
+
+** Documentation
+
+ Bison now installs various files in its docdir (which defaults to
+ '/usr/local/share/doc/bison'), including the three fully blown examples
+ extracted from the documentation:
+
+ - rpcalc
+ Reverse polish calculator, a simple introductory example.
+ - mfcalc
+ Multi-function Calc, a calculator with memory and functions and located
+ error messages.
+ - calc++
+ a calculator in C++ using variant support and token constructors.
+
+* Noteworthy changes in release 3.0.2 (2013-12-05) [stable]
