-* Noteworthy changes in release 2.7.90 (2013-05-30) [beta]
+* Noteworthy changes in release ?.? (????-??-??) [?]
+
+
+* 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
+
+ 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]
+
+** Bug fixes
+
+*** Generated source files when errors are reported
+
+ When warnings are issued and -Werror is set, bison would still generate
+ the source files (*.c, *.h...). As a consequence, some runs of "make"
+ could fail the first time, but not the second (as the files were generated
+ anyway).
+
+ This is fixed: bison no longer generates this source files, but, of
+ course, still produces the various reports (*.output, *.xml, etc.).
+
+*** %empty is used in reports
+
+ Empty right-hand sides are denoted by '%empty' in all the reports (text,
+ dot, XML and formats derived from it).
+
+*** YYERROR and variants
+
+ When C++ variant support is enabled, an error triggered via YYERROR, but
+ not caught via error recovery, resulted in a double deletion.
+
+* Noteworthy changes in release 3.0.1 (2013-11-12) [stable]
+
+** Bug fixes
+
+*** Errors in caret diagnostics
+
+ On some platforms, some errors could result in endless diagnostics.
+
+*** Fixes of the -Werror option
+
+ Options such as "-Werror -Wno-error=foo" were still turning "foo"
+ diagnostics into errors instead of warnings. This is fixed.
+
+ Actually, for consistency with GCC, "-Wno-error=foo -Werror" now also
+ leaves "foo" diagnostics as warnings. Similarly, with "-Werror=foo
+ -Wno-error", "foo" diagnostics are now errors.
+
+*** GLR Predicates
+
+ As demonstrated in the documentation, one can now leave spaces between
+ "%?" and its "{".
+
+*** Installation
+
+ The yacc.1 man page is no longer installed if --disable-yacc was
+ specified.
+
+*** Fixes in the test suite
+
+ Bugs and portability issues.
+
+* Noteworthy changes in release 3.0 (2013-07-25) [stable]
** WARNING: Future backward-incompatibilities!
** Java skeleton improvements
- Contributed by Paolo Bonzini.
-
The constants for token names were moved to the Lexer interface. Also, it
is possible to add code to the parser's constructors using "%code init"
and "%define init_throws".
+ Contributed by Paolo Bonzini.
+
+ The Java skeleton now supports push parsing.
+ Contributed by Dennis Heimbigner.
** C++ skeletons improvements
