Release Notes - v0.51.0

v0.51.0 (June 7, 2026)

Title: Configurable storage tuning, ledger peer snapshots, and Leios-era groundwork

Date: June 7, 2026

Version: v0.51.0

Hi folks! Here’s what we shipped in v0.51.0.

💪 Improvements

• Improved give storage compression more control: Dingo now lets operators tune compression settings, including compression levels, which makes storage behavior easier to match to different workloads.
• Expanded show ledger peer snapshots directly: Dingo now returns ledger peer snapshots through local queries, which makes current peer data easier to inspect during network operations.
• Refined speed up backfill writes for API data: Dingo now uses more consistent database writes during API backfills, which improves write efficiency when large backfills run.
• Enhanced choose log output and verbosity levels: Dingo now lets deployments choose text or JSON logs and set log levels, while keeping text as the default unless JSON is configured explicitly.
• Advanced prepare for Dijkstra and Leios voting: Dingo now includes early groundwork for upcoming era support and vote handling, which broadens readiness for future network changes.
• Strengthened share and serve Leios votes across node flows: Dingo now handles Leios vote sharing and serving, which improves support for emerging vote traffic.
• Embedded bundle the Leios testnet settings: Dingo now includes the Leios testnet configuration bundle in the release, which makes testnet setup easier and more consistent.
• Broadened show Conway era settings in epoch responses: Epoch responses now include Conway era protocol settings, which gives API consumers a clearer view of current network behavior.
• Refreshed improve peer snapshot and topology data: Dingo now updates snapshot based Genesis seeding and refreshes bundled snapshot and topology data, which improves network bootstrapping and peer selection.

🔧 Fixes

• Optimized reduce deferred index rebuild work after backfills: Dingo now splits urgent and lazy rebuild work after API backfills, which lowers rebuild cost and helps recovery finish sooner.
• Updated align the bundled devnet with version 11: The bundled devnet now uses the newer minimum supported version, which keeps local testing aligned with current expectations.
• Stabilized prevent sync stalls close to the chain tip: Dingo now avoids getting stranded close to the chain tip during sync and bootstrap flows, which keeps nodes moving forward more reliably.

🧪 Examples, Docs, and Release Tooling

• Added show a local explorer example: The repository now includes an example for running the explorer against a local API service, which makes local exploration setups easier to follow.
• Documented publish the v0.50.2 release notes: The repository release notes now include the previous version page, which keeps recent release history complete.
