+
+* Semantic parser
+ This old option, which has been broken for ages, is removed.
+
+* New translation
+ Croatian, thanks to Denis Lackovic.
+
+* Incorrect token definitions
+ When fed with `%token 'a' "A"', Bison used to output `#define 'a' 65'.
+
+* Token definitions as enums
+ Tokens are output both as the traditional #define's, and, provided
+ the compiler supports ANSI C or is a C++ compiler, as enums.
+ This helps debuggers producing symbols instead of values.
+
+* Reports
+ In addition to --verbose, bison supports --report=THINGS, which
+ produces additional information:
+ - itemset
+ complete the core item sets with their closure
+ - lookahead
+ explicitly associate lookaheads to items
+ - solved
+ describe shift/reduce conflicts solving.
+ Bison used to systematically output this information on top of
+ the report. Solved conflicts are now attached to their states.
+
+* Type clashes
+ Previous versions don't complain when there is a type clash on
+ the default action if the rule has a mid-rule action, such as in:
+
+ %type <foo> bar
+ %%
+ bar: '0' {} '0';
+
+ This is fixed.

+Changes in version 1.35, 2002-03-25:
+
+* C Skeleton
+ Some projects use Bison's C parser with C++ compilers, and define
+ YYSTYPE as a class. The recent adjustment of C parsers for data
+ alignment and 64 bit architectures made this impossible.
+
+ Because for the time being no real solution for C++ parser
+ generation exists, kludges were implemented in the parser to
+ maintain this use. In the future, when Bison has C++ parsers, this
+ kludge will be disabled.
+
+ This kludge also addresses some C++ problems when the stack was
+ extended.

+Changes in version 1.34, 2002-03-12:
+
+* File name clashes are detected
+ $ bison foo.y -d -o foo.x
+ fatal error: header and parser would both be named `foo.x'
+
+* A missing `;' at the end of a rule triggers a warning
+ In accordance with POSIX, and in agreement with other
+ Yacc implementations, Bison will mandate this semicolon in the near
+ future. This eases the implementation of a Bison parser of Bison
+ grammars by making this grammar LALR(1) instead of LR(2). To
+ facilitate the transition, this release introduces a warning.
+
+* Revert the C++ namespace changes introduced in 1.31, as they caused too
+ many portability hassles.
+
+* DJGPP support added.
+
+* Fix test suite portability problems.
+\f
+Changes in version 1.33, 2002-02-07:
+
+* Fix C++ issues
+ Groff could not be compiled for the definition of size_t was lacking
+ under some conditions.
+
+* Catch invalid @n
+ As is done with $n.
+\f
+Changes in version 1.32, 2002-01-23:
+
+* Fix Yacc output file names
+
+* Portability fixes
+
+* Italian, Dutch translations
