-* Noteworthy changes in release 2.5.90 (2012-07-05) [beta]
+* Noteworthy changes in release ?.? (????-??-??) [?]
+
+** Bug fixes
+
+  Bugs in the test suite have been fixed.
+
+  Some errors in translations have been addressed, and --help now directs
+  users to the appropriate place to report them.
+
+  Stray Info files shipped by accident are removed.
+
+  Incorrect definitions of YY_, issued by yacc.c when no parser header is
+  generated, are removed.
+
+  All the generated headers are self-contained.
+
+** Changes in the format of error messages
+
+  This used to be the format of many error reports:
+
+    foo.y:5.10-24: result type clash on merge function 'merge': <t3> != <t2>
+    foo.y:4.13-27: previous declaration
+
+  It is now:
+
+    foo.y:5.10-25: result type clash on merge function 'merge': <t3> != <t2>
+    foo.y:4.13-27:     previous declaration
+
+** Header guards (yacc.c, glr.c, glr.cc)
+
+  In order to avoid collisions, the header guards are now
+  YY_<PREFIX>_<FILE>_INCLUDED, instead of merely <PREFIX>_<FILE>.
+  For instance the header generated from
+
+    %define api.prefix "calc"
+    %defines "lib/parse.h"
+
+  will use YY_CALC_LIB_PARSE_H_INCLUDED as guard.
+
+* 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).
+
+* 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
