Meltano 0.42.1 is released, and includes a lot of polish as we approach v1. We would love for you to upgrade Meltano and give us feedback... we are ~2 weeks away from announcing v1.0 formally (and bumping the version all the way up at that time) https://meltano.com/blog/2019/09/19/meltano-0-42-1-released/
