Coherent states (CS) have enjoyed during the recent years a considerable development in many avenues of physics and they have grown into a flourishing topic in mathematics, in particular, at the interface of the latter with physics (e.g. quantization methods). A number of textbooks have been devoted to them, as well as a special issue of Journal of Physics A: theoretical and mathematical in 2012. In view of the fast progress that has taken place, it seems that it is now time to assess the situation and survey the recent developments.
