This is probably the fastest update in history, but 2.221 has been released. I found a significant bug with the DNO system that had to be fixed immediately. I also added a ban system to the server and peer. It's simple but effective void AddToBanList(const char *IP); void RemoveFromBanList(const char *IP); void ClearBanList(void); bool IsBanned(const char *IP); IP can be an IP address and can also take a * as a wildcard. Usually you will ban the last segment of an IP in case someone has a dynamic IP such as AddToBanList("123.23.23.*"); This is more effective than what you can accomplish in the context of your game (i.e. checking a list on ID_NEW_INCOMING_CONNECTION ) because it never allows the connection to complete in the first place. If a client or peer attempts to connect and is banned, they will get ID_CONNECTION_BANNED.
