+
+<pre>
+This release includes changes to the http package that will require changes to
+client code.
+
+The finalURL return value of the Client.Get method has been removed.
+This value is now accessible via the new Request field on http.Response.
+For example, this code:
+
+	res, finalURL, err := http.Get(...)
+
+should be rewritten as:
+
+	res, err := http.Get(...)
+	if err != nil {
+		// ...
+	}
+	finalURL := res.Request.URL.String()
+
+Uses of http.Get that assign the finalURL value to _ can be rewritten
+automatically with gofix.
+
+This release also includes an optimization to the append function that makes it
+between 2 and 5 times faster in typical use cases.
