+Changes in version 1.75c:
+
+* 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".
