+        New constructors have been added to <code>SevenZFile</code>
+        that accept <code>char[]</code>s rather than
+        <code>byte[]</code>s in order to avoid a common error of using
+        the wrong encoding when creating the <code>byte[]</code>.
+        This change may break source compatibility for client code
+        that uses one of the constructors expecting a password and
+        passes in <code>null</code> as password. We recommend to
+        change the code to use a constructor without password argument.
