The NA49 experiment has collected comprehensive data on particle productionin nucleus-nucleus collisions over the whole SPS beam energies range, thecritical energy domain where the expected phase transition to a deconfinedphase is expected to occur. The latest results from Pb+Pb collisions between20$A$ GeV and 158$A$ GeV on baryon stopping and light nuclei production as wellas those for strange hyperons are presented.  The measured data on $p$, $\bar{p}$, $\Lambda$, $\bar{\Lambda}$, $\Xi^-$ and$\bar{\Xi}^+$ production were used to evaluate the rapidity distributions ofnet-baryons at SPS energies and to compare with the results from the AGS andthe RHIC for central Pb+Pb (Au+Au) collisions.  The dependence of the yield ratios and the inverse slope parameter of the$m_t$ spectra on the collision energy and centrality, and the mass number ofthe produced nuclei $^3He$, $t$, $d$ and $\bar{d}$ are discussed withincoalescence and statistical approaches. Analysis of the total multiplicityexhibits remarkable agreement between the measured yield for $^3He$ and thosepredicted by the statistical hadronization model.  In addition, new results on $\Lambda$ and $\bar{\Lambda}$ as well as $\Xi^-$production in minimum bias Pb+Pb reactions at 40$A$ GeV and 158$A$ GeV andcentral C+C, Si+Si and Pb+Pb collisions are presented. The system sizedependence of the yields of these hyperons was analysed to determine theevolution of strangeness enhancement relative to elementary p+p collisions.
