Cardano Node 11.1.2 Don Replace 11.1.1 for Stake Pool Operators

Stake pool operators wey don already install Node 11.1.1 go need do another upgrade. Version 11.1.2 na the recommended target for Mainnet, Preprod and Preview for infrastructure wey dey validate blocks and relay ADA transactions.

Cardano Node 11.1.2 Don Supersede the Previous Release

Cardano Node 11.1.2 come out on September 17 after testing find one issue for version 11.1.1. Intersect no describe the issue for its weekly update, but dem talk say the new version don supersede the previous one. Nodes wey dey run 11.1.1 no dey for the recommended baseline again.

The patch optimize memory use when dem dey process time lock scripts. E still update the protocol version minor field for the block header and include cardano-cli 11.2.3.0.

System testing results wey dem publish for Node 11.1.1 still apply. Memory consumption during synchronization small pass version 11.0.1, but e still far below the regression wey dem record for 11.1.0. Small increase for the chain tip get correlation with ledger snapshots.

Node 11.1.2 Carry the 11.1.1 Infrastructure Package

The patch narrow, but e keep the infrastructure changes wey 11.1.1 introduce. V1 LedgerDB and the LMDB storage backend don commot, so operators wey dey use LMDB must migrate go supported alternative.

Ledger snapshots now dey use format wey more predictable and match Mithril. The release line still bring faster transaction forwarding, better Plutus script validation and initial network and consensus support for Peras. Peras still disable by default and e no active for Cardano mainnet.

The same release line complete the removal of the legacy tracing system. Operators wey dey move from the 11.0 series suppose check monitoring and metrics after installation, and downstream teams need consider the breaking changes for cardano-rpc.

Mithril Signer 1.1.9 Join the Same Upgrade

Intersect still recommend Mithril 2630.1-hotfix, wey include mithril-signer 1.1.9. The hotfix correct bug for version 2630.0 wey fit stop signer and aggregator components from fetching blocks and transactions from the chain.

Operators wey dey run Mithril signer don get request to install the two updates as soon as e convenient. After upgrade, make una check tracing, chain data retrieval and synchronization stability.

Cardano still dey for its current ledger era, and the existing rules for processing ADA transactions still dey valid. The infrastructure baseline don change: cardano-node 11.1.2 replace 11.1.1 as the operator target, while Mithril deployments move go mithril-signer 1.1.9.
