Is there any way for me to upgrade my Node-RED JSONata to v1.7?

I would like to use the $distinct() functionality added to JSONata v1.7

Node-RED 1.02 contains JSONata 1.7.0

Thx. I thought Nick implied it was not:

oh - sorry - maybe it's in master waiting for 1.0.3...

Ahh. I guess I'll wait for that.
