Abstract: Current and upcoming studies of post-common-envelope binaries (PCEBs) and specifically sdB binaries reveal crucial properties of such populations. These suggest a radical change in our picture of cataclysmic variable (CV) formation and the tightly interconnected evolution of CVs. I present a modified CV formation picture involving multiple channels, where the observed period gap in CVs is created by a superposition of a short-period sdB channel and a longer-period post-thermal-timescale mass transfer channel rather than the conventional model of a single uniform formation channel and disrupted magnetic braking.
