you can manually replace the binaries, but its probably best to wait until the miner is updated on hives end
cd /tmp
wget https://github.com/rplant8/cpuminer-opt-rplant/releases/download/5.0.29/cpuminer-opt-linux.tar.gz
tar -xvf cpuminer-opt-linux.tar.gz
cp * /hive/miners/cpuminer-opt/rplant/5.0.27
