Q) Are there any plans to replace the library?

From what I know, I think I should use jeromq.

Thanks @heowc. I'll look into getting this merged at some point, but appreciate your patience as I haven't been able to focus on ZeroMQ related stuff lately.

zero-api has been archived From what I know, I think I should use jeromq.

My plan is to continue to update my fork of jzmq-api on an as-needed basis. If I get around to adding more updates, I think we can get the official fork un-archived at some point in the future but I don't want to fight for that if I'm not maintaining it actively. You are of course welcome to use jeromq directly in your own projects, but this project won't use it directly.
