"Eclipse" code was released to gitlab two days ago. I think @gtg is about to make a post where he's running a node for it. Hiveio is also planning to release something more formal. There's a lot of work to be done on the library side still, at least a week worth I suspect, with coordination challenges. Here's commit, it's quite huge: https://gitlab.syncad.com/hive/hive/-/commit/2074917f0735d9bdf22d33f5bdb089df3f6361b0
