　　Smack 4.1.1 发布，此版本主要修复了一下 Bug：

• 　　DIGEST-MD5 challenge/response parsing must handle linear white spaces after the comma
  
• 　　SynchronizationPoint should use signalAll
  
• 　　Integer overflow if both client and server don't specify a max resumption time
  
• 　　isSmResumptionPossible() returns wrong values
  
• 　　DeliveryReceipts auto add should use packet interceptors and should not be requested for messages with ACKs.
  
• 　　Memory leak caused by RosterEntry declaring a strong reference to XMPPConnection
  
• 　　ReconnectionManager's RANDOM_INCREASING_DELAY is erroneously using a fixed value.
  
• 　　Add method to set ProxyInfo in ConnectionConfiguration.Builder
  
• 　　RosterEntry.setName() does not change the name
  

　　详细信息请查看更新日志。

　　Smack是一个开源，易于使用的XMPP（jabber）的 Java 客户端类库。
　　示例代码：
// Create a connection to the jabber.org server.
Connection conn1 = new XMPPConnection("jabber.org");
conn1.connect();
// Create a connection to the jabber.org server on a specific port.
ConnectionConfiguration config = new ConnectionConfiguration("jabber.org", 5222);
Connection conn2 = new XMPPConnection(config);
