Recent developments in the understanding of the M-R diagram of compact stars with first-order phase transition

After a short introduction and review of the structure of compact stars with phase transition to QCD phases, I will present some selected results that have been obtained in 2022. In particular, I will discuss the new findings about ultra-compact hybrid stars and the issue of stability of hybrid stars when the conversion between the two phases is slow at the transition interface.
