Bison is a parser generator in the style of yacc(1). It should be upwardly compatible with input files designed for yacc.
RELEASE NOTES: Several deprecated features were removed, such as support for YYFAIL, yystype, yyltype, YYLEXPARAM, and YYPARSEPARAM. The user epilogue is no longer affected by internal #defines. The recently-introduced dependency on stdio.h when locations are enabled was removed. Caret errors, as introduced in 2.7, are now activated by default. The "-Werror" option was enhanced, and categorization of warnings and errors was modified. Many other changes and various bugfixes were made.
