@anutosh491 If this is the new minimum version, then probably worth changing the yml files for mamba development to check the ci hasn't picked up a version that's less than it.

Hi @mcbarton

So I don't think we are dependent on xeus. Rather xeus is pulled by xeus-zmq so we're good if we have an upper bound on xeus-zmq (< 2.0 ). But yeah for the emscripten build we can try that.
