Fixed bug in expand_rwin feature for IPv6 against servers that don't support window scaling. Many thanks to Thomas Adamczyk for his help.
DNS queries reduced
DNS names are not stored if the query returns an error. This should reduce periodic DNS queries quite a bit.

Added Ping Statistics
cFosSpeed can now display a history of the ping times of the last 5 minutes. This feature is especially useful for gamers who want to diagnose the cause of lag. After a lag experience, you can now conveniently open the ping statistics graph and determine if the lag came from your end of the line or at a remote location, like the game server or some router in between.
Added support for UPnP capable routers
cFosSpeed can now determine the line speed and the maximum line speed by querying the gateway (router) to the Internet. It supports the functionionality of the UPnP Forum's Internet Gateway Device specification as well as the specification of the DSL Forum. So both types of UPnP routers can help to speed up the line calibration in cFosSpeed. We therefore recommend users turn on UPnP in their routers.

How about using cFosSpeed to produce *lag* for a change? This can be easily accomplished with the cFosSpeed class delay management, a feature which is normally used to improve prioritization of the different data streams. Copy both batch files lag.bat and nolag.bat into your cFosSpeed installation directory (where spd.exe is located). Then you can increase the delay by 200 msec by running lag.bat. You can reverse the effect by running nolag.bat.
One technical note: When increasing the lag you will notice that line speed is not the only important factor. Surfing the web etc. can also become slow if the delay is too high.

cFosSpeed checks every 2 days if there is program news. If there is, it displays the mail symbol in the status window and opens this web page when clicked. This feature is on by default. If you are not interested in program news, you can turn it off in the context menu under "Options".
We will post news only a few times per year.
cFosSpeed news policy
Because reaching people via mail becomes more and more difficult and the social networks become more and more widespread, we decided to use Twitter as our short time news service. If there is something new, for example a new cFosSpeed beta version, we will post that on Twitter. At the most we will post only a few times per week. Therefore if you don't already have a Twitter account, please create one and follow @cFosSoftware to get the latest news. You can then conveniently let the cFos Notifier check for our news on Twitter.
We also implemented a news notification in cFosSpeed. When there are very important news available (only a few times per year), like new cFosSpeed release versions, we will update the cFosSpeed news page. As of cFosSpeed v7.01 build 1921, the status windows will display a new symbol and open the cFosSpeed news page, when you click it.
