Most changes to Chesthetica that result in a slightly higher version number are simply to improve the interface or fix a minor bug, by the way. Chesthetica composes everything autonomously (no human intervention) and even chooses the main line of the solution to show you. Do share and try out some of the others too. Some of these problems may be trivial for you, especially if you're a club or master player, but bear in mind that chess lovers can be found at all levels of play. Therefore, do consider some of the other problems available. You can probably find something more to your taste.
