+
+       * NEWS: Version 2.1.
+       * configure.ac (AC_INIT): Likewise.
+
+2006-05-17  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       * data/glr.c (yyreportTree): Make room in yystates for the state
+       preceding the RHS.  This fixes the segmentation fault reported by Derek
+       M. Jones in
+       <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+       (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+       to the user.  Reported for yyreportTree by Derek M. Jones later in the
+       same thread.
+       * THANKS: Add Derek M. Jones.
+       Update my email address.
+       Fix typo in Steve Murphy's name.
+
+2006-05-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+       checking against YYLAST that caused the parser to miss a potential
+       alternative in its diagnostic.
+       Problem reported by Maria Jose Moron Fernandez in
+       <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
+       * data/lalr1.cc (yysyntax_error_): Likewise.
+       * data/yacc.c (yysyntax_error): Likewise.
+       * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
+       tokens, in case we run into an older C compiler.
+       (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
+       Use them to check for the off-by-one error fixed above.
+
+       * data/yacc.c (yytnamerr): Fix typo: local var should be of type
+       YYSIZE_T, not size_t.
+       * tests/regression.at (Trivial grammars): New test, to catch
+       the error fixed by the above patch.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+       * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
+       scheme.
+       Reported by Steve Murphy.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+       * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
+       * data/glr.cc: b4_location_flag is now b4_locations_flag.
+
+2006-05-14  Akim Demaille  <akim@lrde.epita.fr>
+
+       Implement --trace=m4.
+       * src/getargs.c (trace_types, trace_args): Accept trace_m4.
+       * src/output.c (output_skeleton): When set, pass -dV to m4.
+
+       Factor the handling of flags in m4.
+       * src/output.c (prepare): Rename the muscle names debug, defines,
+       error_verbose to debug_flag, defines_flag, error_verbose_flag.
+       * data/c.m4: Adjust.
+       (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
+       Use b4_define_flag_if to define other b4_FLAG_if macros.
+       (b4_location_if): As a consequence, rename as...
+       (b4_locations_if): this, for consistency.
+       Adjust all the skeletons.

        * etc/bench.pm: Shorten bench names.
