There's 457 contributors, but you guys are looking to stabilize things and move forward. So if you have free time, you like machine learning, come give us a hand to maintain this cool library. I would say the historical core devs that I could learn are pretty much mostly doing these days. And that's little time to do really new stuff that is basically left to the newcomers. If I had to wish something for the future, it would be those people were one-time contributors also spent a bit of their time to help us maintain the entire library in longer run.
