✨ Highlights

• Fixed Conway withdrawal redeemer detection by using the withdrawal staking credential, including addresses that combine a base payment script with a staking script.

• Expanded automated test coverage so Linux race tests, Windows tests, and macOS tests run for submitted changes and updates to the primary development line. Docker workflows now run without a path filter, and the relevant test timeouts are longer.

• Prevented automatic snapshots at epoch boundaries when Dingo uses Badger, while preserving manual snapshot creation.

• Strengthened conformance testing with real SQLite, PostgreSQL, and MySQL backends and corrected edge cases in SQL behavior.

• Improved startup chain selection by seeding it with the ledger tip that Dingo has already applied.

• Applied Conway stake pool operator non voter rules to hard fork initiation and bootstrap governance actions.

• Enabled Plutus phase two validation during deep historical replay when historical validation is enabled.

• Extended the release race test package timeout from 20 minutes to 30 minutes.

• Restricted the DevNet harness to Linux so its supported execution environment is explicit.

• Standardized Go formatting with the golines 80 character rule.

• Updated OpenTelemetry OTLP dependencies to v1.46.0 for current telemetry integrations.

• Secured governance ratification and enactment by making them atomic, handling deterministic failures without wedging epoch rollover, and persisting ratification history.

• Refreshed the Blockfrost explorer example with @types/node v26.4.0.

• Stabilized cloud snapshot pruning tests and corrected path handling on Windows.

• Made MIR boundary application atomic, added pot capacity checks, and made effects that exceed the available capacity have no effect.

• Added Bash installation to the Antithesis instrumentation environment.

• Preserved reward balances during Mithril API historical backfill and improved synchronization error logging.

• Introduced support for Dijkstra governance epochs and retained protocol parameters across restarts.

• Enforced the operational certificate KES lifetime during block forging and required validated lifetime data.

• Delayed forged block events until block acceptance and added a durable duplicate slot fence to synchronization state.

• Clarified Preview API bootstrap timing and disk requirements in the documentation.

• Completed consumed UTxO cleanup during shutdown so pending cleanup work drains before the process exits.

• Updated gouroboros to v0.202.4 and preserved Byron PBFT delegation CBOR compatibility.

• Excluded .claude worktrees from Makefile module discovery.

• Upgraded AWS SDK for Go v2 dependencies for current AWS integrations.

• Improved Blockfrost address and account UTxO pagination by bounding page values, calculating totals with count and reference scans, and retrieving only the requested page.

• Isolated concurrent DevNet runs across worktrees with separate Compose projects, network subnets, topology directories, and derived ports. Custom scenario calls require Compose project environment variables.

• Expanded lint coverage across every Go module and Windows build tags, updated pre-commit lint guidance, and hardened related code paths.

• Streamlined conformance runs by replaying each corpus once per backend and resetting only dirty tables, improving diagnostics and backend test efficiency.

• Aligned Blockfrost transaction evaluation with its documented contract by adding the /api/v0/utils/txs/evaluate/utxos endpoint, using the Ogmios v5 response envelope, accepting base16 and base64 input, enforcing strict version handling, and validating additionalUtxoSet.

• Enforced CommitteeTermLimit during UpdateCommittee governance ratification.

• Updated the Docker Go builder image from 1.26.3-1 to 1.26.7-1.

• Verified peer header cryptography before Genesis chain selection observes a peer, while preserving deferred fast sync behavior.

• Refreshed @types/node to 26.4.0 in the dingo-sundae-preview example.

• Recovered abandoned Leios block transaction fetches through the gouroboros dependency update and failover behavior.

• Rejected out-of-range UTxORPC Plutus constructor tags and propagated nested conversion errors.

• Refined Google dependency alignment by updating google.golang.org/api to v0.294.0.

• Clarified strict Koios parity handling by treating departed pools as informational instead of failing the epoch.

• Deferred live stake rebuilds during historical API backfill and rebuilt them once after replay, with checkpoint-safe cancellation and error handling.

• Restored governance and conformance tests by persisting the ratified epoch and boundary slot together and correcting the SPO fixture.

• Tolerated legitimate cross-endorser-block UTxO double consumption on Leios closure paths and validated full transaction hashes.

• Required on-chain Leios voter keys to pass proof-of-possession verification in reference and production modes. Removed the leiosVoterPublicKeys YAML and CLI settings and the DINGO_LEIOS_VOTER_PUBLIC_KEYS environment variable.

• Upgraded Badger to v4.9.6.

• Updated the packaged txtop build stage to v0.16.0.
