✨ Highlights

• Improved keep Dingo aligned with newer Leios behavior: Dingo now follows newer Leios behavior more closely, which helps operators keep preview network sync aligned with current network activity.

• Expanded process newer Leios endorsement data during sync: Dingo now processes newer Leios endorsement data during sync, which improves compatibility with current preview network block flows.

• Refined validate chain progress against configured checkpoints: Dingo now validates chain progress against checkpoints, which gives operators a clearer way to catch invalid chain history during sync.

• Enhanced recognize Musashi naming consistently across the product: Dingo now uses Musashi naming consistently, which makes preview network configuration and operation clearer.

💪 Improvements

• Strengthened show Mithril based catch up progress more clearly: Dingo now reports Mithril based catch up progress more clearly, which makes recovery progress easier to follow during sync.

• Improved check network start times for consistent configuration: Dingo now checks network start times for consistency, which helps operators catch mismatched configuration earlier.

• Expanded reduce repeated peer skip logging during governance updates: Dingo now reduces repeated peer skip logging during governance updates, which makes operational logs easier to read.

• Refined prepare optional storage support builds more cleanly: Dingo now includes optional storage build support, which makes tailored deployments easier to prepare when that support is needed.

🔧 Fixes

• Fixed avoid unnecessary Mithril based rewinds during catch up: Dingo now avoids unnecessary rewinds during Mithril based catch up when the ledger tip is already on the primary chain, which preserves forward replay and supports cleaner recovery.

• Corrected skip waits for outdated Leios endorsement data: Dingo now skips waits for outdated Leios endorsement data, which helps chain progress continue when older data no longer matters.

🧪 Testing, CI, Docs, and Release Tooling

• Updated keep example Node.js type support current in the Sundae preview example: The Sundae preview example now tracks newer Node.js type definitions, which keeps that example easier to maintain.

• Advanced keep TypeScript support current in the Blockfrost explorer example: The Blockfrost explorer example now tracks a newer TypeScript release, which keeps that example aligned with current tooling.

• Polished keep TypeScript support current in the Sundae preview example: The Sundae preview example now tracks a newer TypeScript release, which keeps that example aligned with current tooling.

• Sharpened enforce architecture boundaries during validation: Validation now enforces architecture boundaries between packages, which helps keep ongoing development organized.

• Streamlined publish the v0.55.0 release notes page: The published release history now includes the v0.55.0 notes, which keeps the release record current and easier to review.

• Cleaned polish release note wording for the prior release page: The published v0.55.0 notes now use clearer improvement wording, which makes the release record easier to scan.
