---------------------------------
* 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

  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.
