+Changes in version 1.75d:
+
+* 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

+  This library is normally not useful, but POSIX requires it.
+
+* %lex-param, %parse-param

+* 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.

+  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
