Is the "technobit patch for cgminer" integrated into the official source code for cgminer yet ?
No, that won't happen. You need to apply the patch manually.
Surprising that Technobit requires their customers to do this rather than for them to arrange for it to be done just once.
Can you give me a link to the instructions. Sorry if you have already published this.
