 Changes since 4.0
 -------------------
 
+* [HTTPCLIENT-882] Auth state is not correctly updated if a successful NTLM 
+  authentication results in a redirect. This is a minor bug as HttpClient manages
+  to recover from the problem automatically.
+  Contributed by Oleg Kalnichevski <olegk at apache.org>
+
 * [HTTPCLIENT-881] Fixed race condition in AbstractClientConnAdapter that makes it
   possible for an aborted connection to be returned to the pool.
