-Changes in version 1.75d:
+Changes in version 1.75f, 2002-12-28:

 
 

-* Yacc library now available
-  Bison now installs a small library liby.a containing implementations
-  of Yacc-compatible yyerror and main functions.  This library is
-  normally not useful, but POSIX requires it.
+* In Yacc-style parsers YYLLOC_DEFAULT is now used to compute error
+  locations too.  This fixes bugs in error-location computation.
+
+* Bison now uses a Yacc-style format for conflict reports, e.g.,
+  "conflicts: 2 shift/reduce, 1 reduce/reduce".
+
+* Bison now warns if it detects conflicting outputs to the same file,
+  e.g., it generates a warning for "bison -d -o foo.h foo.y" since
+  that command outputs both code and header to foo.h.
+
+Changes in version 1.75e, 2002-12-24:
+
+* If the user does not define YYSTYPE as a macro, Bison now declares it
+  using typedef instead of defining it as a macro.  POSIX requires this.
+  For consistency, YYLTYPE is also declared instead of defined.
+
+* %union directives can now have a tag before the `{', e.g., the
+  directive `%union foo {...}' now generates the C code
+  `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
+  The default union tag is `YYSTYPE', for compatibility with Solaris 9 Yacc.
+  For consistency, YYLTYPE's struct tag is now `YYLTYPE' instead of `yyltype'.
+
+* `yystype' and `yyltype' are now obsolescent macros instead of being
+  typedefs or tags; they are no longer documented and will be
+  withdrawn in a future release.
+
+* References to the experimental %lex-param and %parse-param directives
+  have been temporarily removed from the manual, since we don't want
+  users to rely upon these features quite yet.
+
+Changes in version 1.75d, 2002-12-13:
+
+* Semicolons are once again optional at the end of grammar rules.
+  This reverts to the behavior of Bison 1.33 and earlier, and improves
+  compatibility with Yacc.
+
+* Type clashes now generate warnings, not errors.
+
+* Yacc command and library now available
+  The Bison distribution now installs a yacc command, as POSIX requires.
+  Also, Bison now installs a small library liby.a containing
+  implementations of Yacc-compatible yyerror and main functions.
+  This library is normally not useful, but POSIX requires it.

 
 * %lex-param, %parse-param
   These now take just one operand, not two.
 
 
 * %lex-param, %parse-param
   These now take just one operand, not two.
 

+* The documentation now emphasizes that yylex and yyerror must be
+  declared before use.  C99 requires this.
+
+* The documentation license has been upgraded to version 1.2
+  of the GNU Free Documentation License.
+
