• Keep over 20 minutes inactive TCP session;

Improvements

• More PPTP implementation support;

Bug Fixes

• Got wrong MAC address if change route during data transfer — Fixed;
• Accelerated PPTP or L2TP interfaces will not be released if MAC or Linux VPN client disconnect — Fixed;

• Non-linear-Packet TCP acceleration support;
• Optimized Retransmission control; now two Conserved modes are supported:
  • High-Conserved mode with more conserved Retransmission Control (a little bit of acceleration effect discount); Or
  • Standard Conserved mode with better acceleration effect;

Bug Fixes

• TCP connection might be reset when download rate was limited too low - fixed;
• Wrong checksum for some XEN kernels - fixed;
