That Tau Ceti has planets is not fresh news. The evidence was obtained already back in 2012 though initially they talked about five planet candidates=))) This study didn't confirm two candidates close to the star (within 0.2 AU) and was inconclusive about one more (there was some evidence but it didn't appeared consistently) However it confirmed the candidates with periods of ~160 and ~600 days and instead proposed two different candidates close to the star.

All those planets are several times heavier than Earth because it's only such planets we can detect right now. I think it's almost guaranteed that there are several light planets so Tau Ceti V exist. But let's wait for more data before constructing the huge space station near Saturn controlled by AI with megalomaniacal tendencies.
