The DAMA/LIBRA experiment (about 250 kg of highly radio-pure NaI(Tl)) is running at LNGS. The results released so far have been obtained in its first phase of measurements (DAMA/LIBRA-phase1) lasted for 7 annual cycles with a total exposure of 1.04 ton $\times$ yr. The DAMA/LIBRA-phase1 and the former DAMA/NaI data (cumulative exposure 1.33 ton $\times$ yr, corresponding to 14 annual cycles) give a model-independent evidence at $9.3\sigma$ CL for the presence of DM particles in the galactic halo. In this talk some new recent analyses performed on the released data will be presented. In particular the investigation of possible diurnal effects will be discussed as well as some of the latest corollary analyses on Dark Matter candidates.
