I'm sorry that I can't release a new Pcap.Net version.
I feel I can't release a version that currently causes a BSOD (Blue Screen Of Death) when I run the unit tests.
If you download the latest sources you should be able to both use the software on Windows 7 and use IPv6 devices.
The BSOD is caused because of the new WinPcap driver.
If you are willing to run the unit tests and tell me if it causes a BSOD on your computer that might help me help WinPcap developer fix the problem.
The many BSODs that my computer had because of this problem were recovered completely so if you run it without any important processes running I believe you shouldn't worry.
