 Bison News
 ----------
+Changes in version 1.75c:
 
-Changes in version 1.75b:
+* "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.
 
-* Bison now parses C99 lexical constructs like digraphs, UCNs, and
-  backslash-newline within C escape sequences, as POSIX now requires.
+* "parsing stack overflow..." -> "parser stack overflow"
+  GLR parsers now report "parser stack overflow" as per the Bison manual.
 
-* --no-line works properly.
+* GLR and inline
+  Users of Bison have to decide how they handle the portability of the
+  C keyword `inline'.

-* 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.
+* %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.

   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".
