+ The next major release will drop support for generating parsers in
+ 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.
+
+** Building bison:
+
+*** Conflicting prototypes with recent/modified Flex.
+
+ Fixed build problems with the current, unreleased, version of Flex,
+ and some modified versions of 2.5.35, which have modified function
+ prototypes.
+
+*** 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.
