On Thursday, January 28th 2016, OpenDNS released the Roaming Client for Windows version 2.0.168 for all customers on the stage track. 

On Tuesday, February 9th 2016, OpenDNS released the Roaming Client for Windows version 2.0.168 for all customers on the first wave of the production release track.

On Monday, February 15th, 2016, OpenDNS released the Roaming Client for Windows version 2.0.168 for all customers on the second wave of the production release track.

On Thursday, March 3rd, 2016, OpenDNS released the Roaming Client for Windows version 2.0.168 for all customers on the final stage of the production release track.  

As some customers on this final stage of the production release track will be upgrading from 2.0.33 to 2.0.168, we've included the changes between those versions below.  Any customers upgrading from 2.0.33 to 2.0.168 will upgrade directly, without ever receiving version 2.0.154, but with all changes in that version being included in 2.0.168.

CHANGE SUMMARY (2.0.154 to 2.0.168)

• Maximum transmission unit (MTU) now set to a lower 1100 size for Umbrella interface to prevent the IP Layer Enforcement tunnel's from generating packet loss.
• Fixed an edge case where dnscrypt-proxy process would continue running after an attempt to terminate the process.

CHANGE SUMMARY (2.0.33 to 2.0.154)

• Include support for future versions of the IP Layer Enforcement platform.

• Added support for selective removal of IP addresses from the default IP block list.

• Fixed a process crash in the DNSCrypt proxy process if it's sent a "Server Status Request" bit.  For information, read: https://support.opendns.com/entries/95628237.

• Fixed a bug in IP Layer Enforcement DLL when black/grey list entries removal was not properly registered by the client.

• Fixed calculation for properly comparing custom IP lists.

• Updated diagnostic tool with knowledge of new ERC files.

• Implemented backoff mechanism when DNS setting conflicts are detected. This affects computers with VPNs on this list: https://support.opendns.com/entries/95819618-Roaming-Client-VPNs-and-VPN-Compatibility. If you have a VPN on this list, please contact Support as behavior may have changed. 

 Major state machine rewrite to improve probing and state transitions are included in this release.  These are comprised of:

• Faster state transitions in response to DNS probe failures, reducing failure timeouts from up to 70 seconds down to six seconds, as referenced in this article: https://support.opendns.com/entries/96432208-Roaming-Client-Captive-Portal-Interaction

• Resolves the issue of no name resolution for X seconds on networks that don't allow traffic to OpenDNS resolvers.

• Improved DNSCrypt proxy process management for possible crashes, relaunching immediately to ensure access to the Internet is uninterrupted.

• Updated DNSCrypt proxy process with a version that allows transparent probes when encrypted.

• Logging improvements for state identification, including reduction in logging redundancy.

• Improved restoring of original DNS settings when a NIC goes down and avoids leaving 127.0.0.1 as the DNS server.

• Better handling of the machine state when IP Layer Enforcement Umbrella interface goes up or down.

• Removed old DLLs that are no longer needed for the DNSCrypt proxy.

• Improved IP Layer Enforcement performance by cutting down on superfluous number of VPN connection attempts.

• Fixed a potential HTTPS block page redirection problem.

• Resolves an issue for some users who may encounter "No Internet Access" triangle.
