Some notable recent changes, updates or improvements include:
-
Cardano-node 8.8.1-pre is now deployed to sanchonet, two-thirds of preprod, one-third of preview and also voltaire private chain networks.
-
Catalyst Voltaire private chain was respun and an updated db-sync and govtool backend deployed after hard fork to Conway era.
-
IOG sanchonet pool block producers are now also signing mithril certificates.
-
A mithril-signer-verifier service now runs on all IOG SRE mithril signers and generates alerts if no recent mithril certificates have been signed.
-
All cardano-parts mithril clients, whether via nixosConfiguration, process-compose jobs or the nix cardano-node entrypoint, will now automatically verify that a trusted IOG pool has signed a mithril certificate prior to using the associated mithril state. If no trusted IOG pool has signed a recent mithril certificate, mithril state usage with be skipped and a classic sync from genesis to tip will be performed.
-
A significant amount of effort was applied towards the upcoming cardano-node 8.9.x-pre release in order to align nixos service module code between cardano-node nixos services, iohk-nix topology generation, cardano-ops legacy code, and cardano-parts module compatibility.
