High level summary​

The SRE team continues work on Cardano environment improvements and general maintenance.

Some notable recent changes, updates or improvements include:

  • Cardano-node, cardano-cli, and db-sync versions are now set to 10.2.1 and 10.4.0.0, 13.6.0.5, respectively, in cardano-parts release v2025-04-03.

  • The blockfrost-platform is now in capkgs and cardano-parts default devShell, pkgs and cluster flakeModules.

  • ConsensusMode cardano-node configuration and supporting files were added to the baseline node configurations in iohk-nix and integrated into cardano-node for the 10.3.x [pre-]release. This will make experimenting with GenesisMode easier. Relevant files and info will be published to the Cardano Book soon.

Repository Work -- Merged​

Capkgs:​

  • Adds the blockfrost platform to capkgs capkgs-pr-4

  • Refactors and expands ci to support fork PRs gracefully. Adds a manual workflow dispatch option with pr_number input for maintainers to authorize a privileged ci run on a forked PR. Utilizes composite actions for easy re-use elsewhere. capkgs-pr-6

Cardano-parts​

  • Sets node release to 10.2.1, cardano-cli release to 10.4.0.0, cardano-db-sync to 13.6.0.5 and mithril-cli to v2513.0. Adds profile-cardano-node-topology SRV record support for cardano-node producers. Fixes a process-compose node health check broken in newer versions of cardano-cli and adds node binary to the nixosCfgs system path. cardano-parts-release-v2025-04-03

  • Adds the blockfrost platform to shell, pkgs, and cluster cardano-parts flakeModules. Futures PRs will extend that to a blockfrost process-compose nix run job as well as dashboard for blockfrost deployments. cardano-parts-pr-62

  • Refactors and expands ci to support fork PRs gracefully. Adds a manual workflow dispatch option with pr_number input for maintainers to authorize a privileged ci run on a forked PR. Utilizes composite actions for easy re-use elsewhere. cardano-parts-pr-63

Cardano-mainnet​

  • Rotates KES, adds bootstrap and stakepool resource specific tags for cost analysis, improves the demo recipes to dynamic waits to avoid brittle time delay failures. Includes the version bumps from cardano-parts release v2025-04-03. cardano-mainnet-pr-32

Cardano-node​

  • Node 10.3.x release branch preparation: SRE contribution for iohk-nix PR#596 integration, CI tests fixup and docker cli arg bug fixup. cardano-node-pr-6143

Iohk-nix​

  • Adds support for genesis mode in node with: node config for genesis mode and related options, checkpoint file for mainnet and updated peer snapshot files for all envs, checkpoint and peer snapshot files are now included in mkConfigHtml output iohk-nix-pr-596
