BalanceNG 3.566 主要是功能增强，改进内容如下：

• The tarpit module and functionality has been implemented allowing to set up a high available IP level tarpit for IPv4 and IPv6 networks in parallel to any additional load-balancing functionality.
  
• The directive "network N tarpit" has been added to allow enabling of the tarpit functionality for selected networks.
  
• The parameters "tarpittrapto" and "tarpitrealto" have been added controlling the timeouts of tarpit session table entries.
  
• A new online example explains the basic setup in 3 steps: Example 18 (Implementing a high available tarpit for IPv4 and IPv6 with the tarpit module).
  
• The manual has been updated accordingly.
  
  

BalanceNG 3.562 版本主要是修改默认参数：

• VRRP v3 according to RFC 5798 is now the default master/backup HA negotiation protocol (by setting the default of parameter "vrrpversion" to 3).
  
• In order to enable session table synchronization the bngsync functionality and protocol now needs to be  configured as shown in this example: Example 17 (Activating Session Table Synchronization with bngsync).
  
• The prior use of session table synchronization with non standard VRRP v2 packets is now deprecated (but still functional as before).
  
• The default value of parameter "sessionsyncack" is now 1 (active), thus enabling synchronization acknowledgements automatically.
  
• The default value of parameter "sessionautoresync" is now 1 (active), the backup node automatically requests a resynchronization of the session table on restart.
  
• A "name" column for the output of "show servers" has been added.
  
• A bug with parameter settings for the upcoming tarpit module and functionality has been resolved.
  
• The manual has been updated accordingly
  

BalanceNG 3.560 版本主要是 bug 修复：

• A command parsing issue with the "arp" command has been fixed, IPv4 and IPv6 addresses as are now accepted as expected.
  
• An issue with misleading tp_drops packet statistics display on Linux after a reload has been fixed (as shown by "show interfaces").
  
• The error message on CLI after a "reload" with a fixed configuration is now cleared as expected.
  
• A minor title display formatting bug on "show session <string>" has been fixed
