Hi, we're going to update pallets clojure dependencies in order to be able to use spec in combination with pallet. At the moment 'it works on our system' 🙂. Maybe someone is interested in integration-testing our current work? You can test using [dda/pallet "0.8.13-SNAPSHOT"] (avail. on clojars) as drop-in-replacement for latest pallet [com.palletops/pallet "0.8.12"] Your feedback is very welcome in #dda-pallet
