Is Adobe Premiere Rush still being developed?

I haven't seen much in the way of updates or new features in a long time.  Does anyone kow if Premiere Rush is still under development?  There are some basic features that are still missing and I kind of expected them to add these features over time but that has not happened.

I have Premiere Pro, but feel the learning curve is quite significant and prefer Rush for my videos as they are rather simple.  But some of the missing features are just crazy to me.

Thanks for the help!
