The author of the popular SRBminer CryptoNight AMD GPU miner has just updated his new mining software called SRBMiner-MULTI CPU and AMD GPU Miner to version 0.1.2 Betta adding support for the new kangaroo12 (k12) algorithm on GPU and CPU. The miner is targeted at algorithms for CPU mining as well as some CPU and GPU ones for more recent AMD-based video cards (R9 2xx series and newer)… other than the CN-based algorithms that the other SRBminer Cryptonight oriented miner software for AMD GPU supports. The latest version also fixes the dev fee at a lower 0.85% value for all of the supported algorithms (no more lower or higher developer fee) as well as comes with some bug fixes.
Do note that just like his CryptoNight GPU miner, this new CPU and GPU AMD miner is also available only for Windows (Linux version might be coming out soon as well hopefully) as a pre-compiled binary and there is a built-in developer fee now fixed at 0.85% for all supported algorithms. You can find the currently supported algorithms below:
