Changes in version 2.1a:
-* DJGPP support added.
+* GLR, C++ LALR(1) parsers.
+ These parser skeletons are now distributed with the same special
+ license exception that the C LALR(1) parser skeleton has had since
+ Bison 1.24. Hence the FSF imposes no copyright restriction on the
+ output of Bison when it is generating such parsers.
+
+* %expect, %expect-rr
+ Incorrect numbers of expected conflicts are now actual errors,
+ instead of warnings.
+
+* GLR, YACC parsers.
+ The %parse-params are available in the %destructor's (and the
+ experimental %printer's) as per the documentation.
+
+* Bison now warns if it finds a stray `$' or `@' in an action.
* %require "VERSION"
- To specify the youngest version of Bison accepted by the grammar file.
+ To specify that the grammar file depends on features implemented in
+ Bison version VERSION or higher.
* lalr1.cc: The token and value types are now class members.
The tokens where defined as free form enums and cpp macros. YYSTYPE
If you wish to update, then make sure older version of Bison will
fail using `%require "2.1a"'.
+* DJGPP support added.
