Is dYdX v4 live?

Hello there, I'm curious to know if the latest version of dYdX, specifically version 4, is currently live and operational? I've been following the development of this platform closely and I'm excited to see what new features and improvements it brings to the decentralized finance and cryptocurrency ecosystem. Could you please provide an update on its status and if there are any known issues or limitations that users should be aware of? Thank you in advance for your help!
