The date of the last update is right above the comment section. It was 6 months ago. v0.17 is almost done.
I've had a lot of personal issues come up, and that along with putting more effort into development has lead to this update taking longer.
As discussed in a recent Dev Diary, I'm changing my work schedule to hopefully get out more updates per year. Working on the same schedule with the increased work load isn't viable anymore as it's much more stressful.
