In the discussion of new results from nucleus-nucleus collisions the emphasis is on strange meson and baryon production at different energies - for the first time at 40 GeV A - with the study of light nuclei.9 pages, 21 figures, proceedings of ISMD2000High Energy Physics - ExperimentRecent NA49 results on Pb+Pb collisions at CERN SPStext
