+** Future changes

+ The next major release of Bison will drop support for the following
+ deprecated features. Please report disagreements to bug-bison@gnu.org.

+*** K&C parsers

+ Support for generating parsers in K&R C will be removed. Parsers
+ generated for C supprt ISO C90, and are tested with ISO C99 and ISO C11
+ compilers.
+
+*** Deprecated features
- The next major release will drop support for generating parsers in K&R C,
- and remove the definitions of yystype and yyltype (removal announced since
- Bison 1.875). YYPARSE_PARAM and YYLEX_PARAM, which were deprecated in
- favor of %parse-param and %lex-param (introduced in Bison 1.875 too), will
- no longer be supported.
+ The definitions of yystype and yyltype will be removed, as announced since
+ Bison 1.875. Use YYSTYPE and YYLTYPE only.
-** The generated header is included (yacc.c)
+ YYPARSE_PARAM and YYLEX_PARAM, which were deprecated in favor of
+ %parse-param and %lex-param (introduced in Bison 1.875), will no longer be
+ supported.
+
+*** The generated header will be included (yacc.c)
Instead of duplicating the content of the generated header (definition of
- YYSTYPE, yyltype etc.), the generated parser now includes it, as was
- already the case for GLR or C++ parsers.
+ YYSTYPE, yyparse declaration etc.), the generated parser will include it,
