✨ Highlights

• Recorded the v0.67.1 release entry so the release index stays complete.

• Preserved the live stake index during API backfill so backfilled data keeps stake history available.

• Aligned the DRep list and response with Blockfrost expectations so governance lookups return the same shape across endpoints.

• Added Blockfrost support for GET /addresses/{address} so address lookups return Blockfrost compatible responses.

• Updated bark to keep the release dependency set current.

• Fixed pointer snapshot UTxO handling so snapshots stay consistent during pointer based queries.

• Enabled stake-address-info LSQ queries so stake address lookups can return the expected ledger state.

• Refreshed the example @blaze-cardano/sdk dependency so the sample app stays current.

• Refined the AWS SDK for Go v2 dependency set to the newer release.

• Upgraded cloud.google.com/go/storage to the newer release.

• Restored DRep activity from certificates so governance lookups stay current.

• Adjusted the AWS SDK for Go v2 credentials dependency to the newer release.

• Matched exact-address UTxO lookups across Blockfrost and UTxO-RPC so both interfaces return the same outputs.

• Refactored the plugin system and kept configuration migration compatible with existing setups.

• Aligned the AWS SDK for Go v2 config dependency with the newer release.

• Improved rollback ordering in Ouroboros so rollback observation happens before the apply gate advances.

• Hardened genesis restart safety so restarts recover cleanly after genesis state changes.

• Stabilized open database ownership safety so shared database access remains safe across ownership changes.

• Protected reward_live_stake snapshot handling so mark snapshot processing uses the live stake view.

• Recovered the replay path loop so failures can restart cleanly instead of stalling the node.

• Parsed Leios pool reward accounts correctly so reward account data remains available during ledger processing.

• Applied backpressure to event processing so the node preserves events instead of dropping them under load.

• Welcomed @mmahut as a new contributor for this release.
