Is this project still maintained?

Is dbREST still in active development? Will there be any new features?

Hello, most of my free time is going into https://github.com/slingdata-io/sling-cli
I wouldn't say it's dead. It's still maintained (it powers dbnet, which I use daily). But no new features at the moment.
Feel free to submit PRs.
