  We present recent results of the SPS experiment NA49 on production of strange
particles and event-by-event fluctuations of mean $p_t$ and of charged particle
ratios in central Pb+Pb collisions at various beam energies (40, 80, 158 AGeV)
as well as in different collisions at 158 AGeV, going from p+p over light-ion
collisions to peripheral and central Pb+Pb.
