It used to be an error only if used in non GLR mode, _and_ if there are
reduce/reduce conflicts.
-* Noteworthy changes in release ?.? (????-??-??) [?]
-
-** %language is no longer an experimental feature.
-
- The introduction of this feature, in 2.4, was four years ago. The --language
- option and the %language directive are no longer experimental.
+* Noteworthy changes in release 2.7 (2012-12-12) [stable]
** Bug fixes
Warnings about uninitialized yylloc in yyparse have been fixed.
+ Restored C90 compliance (yet no report was ever made).
+
** Diagnostics are improved
*** Changes in the format of error messages
These features are experimental in this version. More user feedback
will help to stabilize them.
+ Contributed by Alex Rozenman.
** IELR(1) and canonical LR(1):
The current Java interface is experimental and may evolve. More user
feedback will help to stabilize it.
+ Contributed by Paolo Bonzini.
** %language
Bison can now generate an XML report of the LALR(1) automaton using the new
"--xml" option. The current XML schema is experimental and may evolve. More
user feedback will help to stabilize it.
+ Contributed by Wojciech Polak.
** The grammar file may now specify the name of the parser header file using
%defines. For example:
