----------
+* 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.
+
+** Changes in the manual:
+
+*** %printer is documented
+
+ The %printer directive, supported since at least Bison 1.50, is
+ finally documented. The %mfcalc example is extended to demonstrate
+ its use of printer.
+
+ The C++ parsers now also support yyoutput (as an alias to
+ debug_stream ()) for consistency with the C skeletons.
+
+*** Several improvements have been made:
+
+ 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.
+
+** Changes to the build system:
+
+*** 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.
+
+*** The install-pdf target work properly:
+
+ Running "make install-pdf" (or -dvi, -html, -info, and -ps) no
+ longer halts in the middle of its course.
+
* Changes in version 2.5 (2011-05-14):
** Grammar symbol names can now contain non-initial dashes:
** The output file does not define const, as this caused problems when used
with common autoconfiguration schemes. If you still use ancient compilers
that lack const, compile with the equivalent of the C compiler option
- `-Dconst='. autoconf's AC_C_CONST macro provides one way to do this.
+ `-Dconst='. Autoconf's AC_C_CONST macro provides one way to do this.
** Added `-g' and `--graph'.
\f
* Changes in version 1.26:
-** Bison now uses automake.
+** Bison now uses Automake.
** New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
** Tokens can now be specified as multiple-character strings: for
example, you could use "<=" for a token which looks like <=, instead
-of chosing a name like LESSEQ.
+of choosing a name like LESSEQ.
** The %token_table declaration says to write a table of tokens (names
and numbers) into the parser file. The yylex function can use this
Output file does not redefine const for C++.
