+  The constants for token names were moved to the Lexer interface.

+* %language is an experimental feature.
+
+  We first introduced this feature in test release 2.3b as a cleaner
+  alternative to %skeleton.  Since then, we have discussed the possibility of
+  modifying its effect on Bison's output file names.  Thus, in this release,
+  we consider %language to be an experimental feature that will likely evolve
+  in future releases.
+
+* Forward compatibility with GNU M4 has been improved.
+
+* Several bugs in the C++ skeleton and the experimental Java skeleton have been
+  fixed.

+* Java

+* %language

+  This new directive specifies the programming language of the generated
