<div dir="ltr">I upgraded a computer (Windows 7 x64) to from 2.1.7 to 2.2.0 and I immediate noticed that it now gave me DNS as an IPv6 address which is not what my DHCP should be handing out and I didn't have this with 2.1.7. I also noticed that after I disconnected I wasn't able to reconnect until I rebooted the computer but I didn't have a chance to see if this was once off or repeatable.<div>

All,<br>
<br>
So its been quite some time since we have released a new build from the head branch which will become the 2.2.0 release version. I'm pleased to be moving beyond the 2.1.7 series as there are many enhancements and changes in the head branch that have yet to make it into a stable VPN client release. I really need everyone's help to test this release as it contains a few critical bug fixes in the kernel drivers which will take some time to pass through WinQual certification. This was a major bottleneck for the 2.1.7 release so we hope to get this completed much quicker this time around. All the kernel driver related items on the 2.2.0 todo list have been completed. Unless regressions are reported ( and I don't expect any ), we should be able to qualify this version of the driver.<br>
<br>
What's new in this release? I'll start with the major bug fixes ...<br>
<br>
1) A myriad of tools were used to test user binaries to shake out any memory leaks that were present. Embarrassingly, there were at least a dozen problems found and corrected, none of them kernel driver related. If you noticed a memory leak related to the VPN client on any platform, please test this build.<br>
<br>
2) The WLAN related problem that could be avoided by disabling the Microsoft Virtual WiFi Miniport Adapter problem has now been worked around at the driver level. As long as you are connected to an AP, the VPN client should operate normally. Using adhoc networks are currently unsupported. If you currently have the Virtual WiFi adapter disabled, please re-enable it and test this build.<br>
<br>
3) The problem related to slow TCP performance when direct adapter mode was in use has been corrected. This was due to the miniport TCP Large Segment Offload feature not being emulated in the LWF driver send path. If you currently have LSO disabled on your adapter, please re-enable it and test this build.<br>
<br>
4) The daemons no longer wake up every 500ms to check for an exit status. It's quite possible that this caused unnecessary CPU activity while in a low power state. This may cause a laptop battery to drain faster even with the VPN client disconnected. To accomplish this on Windows platforms, we now use asynchronous communication functions in all driver interface library calls. This has also increased throughput on low latency connections by a factor of 3. Less objective tests show that this change also has a positive impact on high latency connections such as mobile broadband adapters. If you have a native Windows 7 mobile broadband connection, please test this build.<br>
<br>
A huge number of other minor bug fixes are included in this release when compared to the last 2.2.0 alpha. In many ways, this release is likely more polished than even the 2.1.7 release. The reason its still marked as alpha is that we still have more feature work and the driver certification to complete before calling it a beta. If you have time, please help test this build! We really need as many eyeballs on it as possible to help us located driver bugs or regressions before we spend the time and funds to re-certify the drivers.<br>
<br>
Thanks to everyone in advance,<br>
<br>
