 * Noteworthy changes in release ?.? (????-??-??) [?]
 
 
-* Noteworthy changes in release 2.5.90 (2012-07-05) [beta]
+* Noteworthy changes in release 2.6.2 (2012-08-03) [stable]
+
+** Bug fixes
+
+  Buffer overruns, complaints from Flex, and portability issues in the test
+  suite have been fixed.
+
+** Spaces in %lex- and %parse-param (lalr1.cc, glr.cc)
+
+  Trailing end-of-lines in %parse-param or %lex-param would result in
+  invalid C++.  This is fixed.
+
+** Spurious spaces and end-of-lines
+
+  The generated files no longer end (nor start) with empty lines.
+
+* Noteworthy changes in release 2.6.1 (2012-07-30) [stable]
+
+ 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.
+
+*** Stray @ or $ in actions
+
+  While Bison used to warn about stray $ or @ in action rules, it did not
+  for other actions such as printers, destructors, or initial actions.  It
+  now does.
+
+** Type names in actions
+
+  For consistency with rule actions, it is now possible to qualify $$ by a
+  type-name in destructors, printers, and initial actions.  For instance:
+
+    %printer { fprintf (yyo, "(%d, %f)", $<ival>$, $<fval>$); } <*> <>;
+
+  will display two values for each typed and untyped symbol (provided
+  that YYSTYPE has both "ival" and "fval" fields).

   The next major release of Bison will drop support for the following
   deprecated features.  Please report disagreements to bug-bison@gnu.org.
