+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.
+
+* 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.
+
+* %lex-param, %parse-param
+ These new directives are preferred over PARSE_PARAM and LEX_PARAM.
+ In addition, they provide a means for yyerror to remain pure, and
+ to access to the current location.
+
+ #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".
+
+Changes in version 1.75a, 2002-10-24:
+
+* 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.
