+Changes in version 1.75d, 2002-12-13:

 
 

-* Bison can no longer be built by a K&R C compiler; it requires C89 or
-  later to be built.  This change originally took place a few versions
-  ago, but nobody noticed until we recently asked someone to try
-  building Bison with a K&R C compiler.
+* 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.
+
+* 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.
+
+Changes in version 1.75c, 2002-11-25:
+
+* "parse error" -> "syntax error"
+  Bison now uniformly uses the term "syntax error"; formerly, the code
+  and manual sometimes used the term "parse error" instead.  POSIX
+  requires "syntax error" in diagnostics, and it was thought better to
+  be consistent.
+
+* "parsing stack overflow..." -> "parser stack overflow"
+  GLR parsers now report "parser stack overflow" as per the Bison manual.
+
+* GLR and inline
+  Users of Bison have to decide how they handle the portability of the
+  C keyword `inline'.
+
+Changes in version 1.75b, 2002-11-13:
+
+* %destructor
+  It is now possible to reclaim the memory associated to symbols
+  discarded during error recovery.  This feature is still experimental.
+
+* Bison now parses C99 lexical constructs like UCNs and
+  backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires.
+
+* --no-line works properly.

 
 * %error-verbose
   This new directive is preferred over YYERROR_VERBOSE.
 
 * %error-verbose
   This new directive is preferred over YYERROR_VERBOSE.

+  #defining yyerror to steal internal variables is strongly
+  discouraged.  It is not guaranteed to work for ever.

+* #line
+  Bison now recognizes #line in its input, and forwards them.
+
+* #line
+  File names are properly escaped. E.g. foo\bar.y give #line 123 "foo\\bar.y".
