Just to notify all Technitium MAC Address Changer users, new version is about to be complete and you can expect a beta version this month.
New version, completely written from scratch, will have full IPv6 support. A complete change in code base was done to make the new version more efficient and easy to use.
People who have emailed me earlier for support would get email notification when the software is released. Others, keep watching this space for Technitium MAC Address Changer version 6!
