Overview:

Sets node release to 10.4.1, cardano-cli release to 10.8.0.0 and mithril to v2517.1. Adds mithril ancillary key support for signed volatile and ledger state. Switches to a blockPerf fork which can be used without publishing metrics to CF, ex: for testnet usage. Includes additional misc fixes and improvements detailed below.

Details:

Important versioning updates in this release are underlined:

• Adds snapshot-converter to pkgs, devShell, nixosCfg systemPackages
• Adds pool margin parameterization for job-register-stake-pools nix job
• Adds a blockperf fork which allows blockperf usage without publishing metrics to CF; ex: testnet usage
• Adds nixosConfigurations to hydraJobs and automatically disables abortOnMissingIpModule as needed for the hydra builds to enable building without ipv4/6 secrets present
• Adds location keys to all nixosModules to avoid double import eval failures
• Adds ssm-session-manager to the ops devShell for movement towards closed port 22 ssh
• Adds mithril ancillary key support for ledger and volatile component snapshot pull (may still replay genesis in some cases until the next mithril release -- this is a known issue)
• Updates cardano-node systemd preStart scripts, bash entrypoint scripts and process-compose jobs to utilize mithril ancillary keys for preview and preprod networks
• Fixes template recipe apply-bootstrap failures when the .ssh_key is missing
• Cleans up pre-push unnecessary symlink pollution

Recommended Updates:

• Update the cardano-parts pin to this release version v2025-05-22
• Apply the template Justfile diff and patch or clone recipes on files described below.

Action Items:

Diff and patch the following files with just template-diff "$FILE" and then
just template-patch "$FILE". Looking at the short PR diff for these files
found at directory templates/cardano-parts-project/ prior to diffing and
patching against your own repo can also be helpful.

Alternatively, if you know you would just like to mirror any of these template
files without diffing or patching, use the just template-clone "$FILE"
recipe.
