See our history. Very simply put - this project is the continuation of the contrib project.
nREPL currently doesn’t support ClojureCLR. The reason for this is that it leverages Java APIs internally. There’s an nREPL port for ClojureCLR, but it’s not actively maintained and it doesn’t behave like the Clojure nREPL.
There’s no exact roadmap for the 1.0 release. Roughly speaking the idea is to release 1.0 once everything essential has been migrated from the legacy contrib nREPL to the new nREPL (e.g. lein, boot, key middleware) and we’ve cleaned up the most important tickets from our backlog.
Sure! See third party middleware for details.
