Is raw using binary protocol? (for ex: send\receive UInt8Array Buffer without converting to hex string for bytea column)

No, that unfortunately didn't make it into this release. I want to add that in a future update, first at least for bytea, but then also for other types that benefit from it.

Is there any timeline example? Like http://visjs.org/timeline_examples.html

Thanks for bringing this up. It’s possible to create visualization like this using Muze easily. Will create an example and keep you updated. Should we reach out to you once done (if yes, let me know how)!
