 * `partner-chains-cli` does not use `pc-contracts-cli` in `prepare-configuration` wizard, it uses `partner-chains-cardano-offchain` crate instead.
 * Update cardano-node to 10.1.2
 * Bumped `partner-chains-smart-contracts` version to v6.2.2
+* Added d-parameter and permissioned-candidates transaction building (not wired in)
