 * Noteworthy changes in release ?.? (????-??-??) [?]
 
-** Future changes
+ Bison no longer executes user-specified M4 code when processing a grammar.
+
+** Future Changes
+
+  In addition to the removal of the features announced in Bison 2.6, the
+  next major release will remove the "Temporary hack for adding a semicolon
+  to the user action", as announced in the release 2.5.  Instead of:
+
+    exp: exp "+" exp { $$ = $1 + $3 };
+
+  write:
+
+    exp: exp "+" exp { $$ = $1 + $3; };
+
+** Bug fixes
+
+*** Type names are now properly escaped.
+
+*** glr.cc: set_debug_level and debug_level work as expected.
+
+** Type names in printers and destructors
+
+  For consistency with rule actions, it is now possible to qualify $$ by a
+  type-name in printers and destructors.  For instance:
+
+    %printer { fprintf (yyo, "(%d, %f)", $<ival>$, $<fval>$); } <*> <>;
+
+  will display two values for each typed and untyped symbol (provided
+  that YYSTYPE supports it).
+
+* Noteworthy changes in release 2.6 (2012-07-19) [stable]
+
+** 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
+*** K&R C parsers
 
   Support for generating parsers in K&R C will be removed.  Parsers
   generated for C support ISO C90, and are tested with ISO C99 and ISO C11
