+* Changes in version 2.5.1 (????-??-??):
+
+** Future changes:
+
+  The next major release will drop support for K&R C.
+
+** yacc.c: YYBACKUP works as expected.
+
+** glr.c improvements:
+
+*** Location support is eliminated when not requested:
+
+  GLR parsers used to include location-related code even when
+  locations were not requested, and therefore not even usable.
+
+*** __attribute__ is preserved:
+
+  __attribute__ is no longer disabled when __STRICT_ANSI__ is defined
+  (i.e., when -std is passed to GCC).
+
+** lalr1.java: several fixes:
+
+  The Java parser no longer throws ArrayIndexOutOfBoundsException if
+  the first token leads to a syntax error.  Some minor clean ups.
+
+** C++11 compatibility:
+
+  C and C++ parsers use nullptr instead of 0 when __cplusplus is
+  201103L or higher.
+
+** C++ locations:
+
+  The position and location constructors (and their initialize
+  methods) accept new arguments for line and column.  Several issues
+  in the documentation were fixed.
+
+** liby is no longer asking for "rpl_fprintf" on some platforms.
+
+** Several improvements have been made to the manual:
+
+  The layout for grammar excerpts was changed to a more compact
+  scheme.  Named references are motivated.  The description of the
+  automaton description file (*.output) is updated to the current
+  format.  Incorrect index entries were fixed.  Some other errors were
+  fixed.
+
+** Warnings during the build procedure have been eliminated.
+
+** Several portability problems in the test suite have been fixed:
+
+  This includes warnings with some compilers, unexpected behavior of
+  tools such as diff, warning messages from the test suite itself,
+  etc.
+
+* Changes in version 2.5 (2011-05-14):
