+       Rename "default rule" to "default reduction".
+       This includes changing variable names in code, changing
+       comments, and renaming %define lr.default_rules to %define
+       lr.default_reductions.
+       * NEWS (2.5): Update IELR documentation.
+       * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c:
+       Adjust YYDEFACT and yydefact_ documentation.
+       * doc/bison.texinfo (Decl Summary): Adjust lr.default_reductions
+       and lr.type documentation.  Make some other wording
+       improvements.
+       (Glossary): Adjust cross-references and Default Reduction
+       definition.
+       * src/lalr.c (state_lookahead_tokens_count): Adjust code.
+       Remove a confusing comment pointed out by Akim Demaille.
+       (initialize_LA): Adjust code.
+       * src/print-xml.c (print_reductions): Adjust code.
+       * src/print.c (print_reductions): Adjust code.
+       * src/reader.c (reader): Adjust code.
+       * src/tables.c (action_row): Adjust code.
+       (token_actions): Adjust code.
+       * src/tables.h: Adjust YYDEFACT documentation.
+       * tests/input.at (%define lr.default_rules invalid values):
+       Rename test group to...
+       (%define lr.default_reductions invalid values): ... this, and
+       update grammar file and expected output.
+       * tests/reduce.at (AT_TEST_LR_DEFAULT_RULES): Rename to...
+       (AT_TEST_LR_DEFAULT_REDUCTIONS): ... this, and update.
+
+2009-04-21  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       Document %define lr.type and lr.default_rules.
+       * NEWS (2.5): Add an entry.
+       * src/getargs.c (usage): Mention IELR(1) and canonical LR(1)
+       besides just LALR(1) and GLR(1).
+       * doc/bison.texinfo (Introduction): Likewise.
+       (Language and Grammar): Bison is no longer limited to LALR(1)
+       restrictions.
+       (GLR parsing): Say deterministic or LR(1) rather than LALR(1)
+       when trying to distinguish from GLR.  Talk about LR(1) grammars
+       rather than LALR(1) grammars.
+       (Decl Summary): In %define api.push_pull entry, say it applies
+       to deterministic parsers in C rather than LALR(1) parsers in C.
+       Add lr.default_rules entry.
+       Add lr.type entry.
+       (Mystery Conflicts): Bison is no longer limited to LALR(1)
+       restrictions.
+       (Generalized LR Parsing): Same changes as for the previous GLR
+       section.
+       (Memory Management): Say deterministic rather than LALR(1).
+       (Understanding): Correct some bison output.
+       Index discussion of "accepting state".
+       Say deterministic rather than LALR(1).
+       (Bison Options): In --yacc entry, say deterministic rather than
+       LALR(1).
+       In --report, --graph, and --xml entries, just don't mention
+       LALR(1).
+       (C++ Parsers): Say deterministic rather than LALR(1).
+       (Table of Symbols): Likewise in YYSTACK_USE_ALLOCA entry.
+       (Glossary): Add Accepting State, Consistent State, Default Rule,
+       and IELR(1) definitions.
+       In Generalized LR (GLR) definition, make same changes as in
+       previous GLR sections.
+       In LALR(1) definition, say Bison uses LALR(1) by default rather
+       than implying Bison is limited to LALR(1).
+       (LocalWords): Add IELR.

        Finish implementing %define lr.type.
