Repository Work -- Merged

Cardano-airgap

cardano-airgap PR#12:

• Bumps disko to v1.13.0
• Fixes running disko scripts in the iso environment after bumping nixpkgs by adding required deps via closure path reference to /etc/install-closure.
• Adds binary iso-versioning, available from devShell and in the iso environment which provides relevant component version info in centered GitHub md table format.

Cardano-faucet

cardano-faucet PR#17:

• Updates the flake inputs and haskell dependencies of cardano-faucet. Specifically, upgrade cardano-api to 10.19 for cardano-node 10.6.x compatibility, and fix the resulting compiler errors. This prepares the faucet for functioning through the upcoming intra-era hard fork.

Iohk-nix

cardano-node-release/10.5.4 branch:

• Provides a preview environment checkpoint file as well as per-environment peer snapshot file and "use ledger peers after" slot updates for cardano-node release 10.5.4.
