Last 2 years there was an update before Christmas.
We can always hope.
Yes... but you also have to take into account that at that time, in one you only had to work with adding a transformation and perhaps an new area, while in another it was a large zone (jail) and a few more elements.
Now and due to great popular demand, now Vrel is working on the pregnancy, which not only leads to the MC and his different transformations having to work, but also for consistency, the NPCs (except those who have name until a special "event" occurs) they can also get pregnant or can get others pregnant, which will also lead to the creation of secondary events that revolve around that theme.
If to this is added that by Vrel's desire objects such as condoms were added (and that these have an internal probability of being useful or not) well... normal that the tradition will probably be broken, since if by itself for a few objects, elements and additions always in each version there are a lot of bugs, what do you expect from something as dense as a new mechanic of that level at this point.
That of course... that's why when the bases of a game are created, the characteristics and elements to exist are first defined or, failing that, the "space" and "shape" are left from the source, enough to be able to add them in the future, new mechanics and elements, without having to work on each detail part by part in principle, although in the vast majority of cases it is a Russian roulette, it works or not.
