Nothing has stopped, the daily builds are coming out with the same frequency as they always have, for both Max and C4D. As for finding the features exciting, as a product matures the improvements become more incremental and less dramatic, this happens to all software - back in the early days there are so many major things missing, every release brings something "huge". Now, whether you find a feature exciting or not is less universal and more dependent on your specific workflow and needs :)
The lister rewrites, with the improved functionality and speed, are going to be very useful for many people in their daily tasks - is it "exciting"? Hard to say, but the amount of time saved and making someone's working day easier is still important.
Same with having multiple inputs and outputs in a map, so you no longer need to adjust two or three or more maps (or alternatively set up controller nodes) - again, it will make a difference to many daily tasks. As will the new possibilities with Decals, now that individual channels can be isolated.
In the end, if you feel the features are not exciting for your workflow, that's what the Feature Requests boards are for - tell us what feature you would like that would be exciting for you :)
