+
* Russian translation added.
* NLS support updated; should hopefully be less troublesome.
* Added the old Bison reference card.
+
+* Added `--locations' and `%locations'.
+
+* Added `-S' and `--skeleton'.
+
+* `%raw', `-r', `--raw' is disabled.

+
+* New directives.
+ `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
+ `%debug'.
