Title: Clarify Preview swap guidance, expand Leios coverage, and improve database reliability

Date: May 28, 2026

Version: v0.49.1

Hi folks! Here’s what we shipped in v0.49.1.

Added clarify SQL database guidance: The database guide now maps storage behavior and common query paths so database work is easier to understand and maintain.
Introduced show Preview swap flows more clearly: The DingoSwap example now shows how applications can read pool data, manage assets, build swap orders, and connect a browser wallet for SundaeSwap V3 activity on Preview.
Expanded broaden Leios coverage for connected applications: Dingo now returns merged Leios ranking and endorser information so downstream services and testing tools can work with a fuller view of chain activity.
Enabled apply reward voting rules automatically: Dingo now applies reward account delegation rules automatically when governance voting follows CIP 1694.

Improved keep reward tracking more complete: Dingo now preserves reward state across runs, which improves continuity for reward tracking and treasury views.
Enhanced keep Preview swap setup aligned with current browser tooling: The DingoSwap example now fits current browser build tools more cleanly, which makes local setup and wallet connection behavior more reliable.
Updated keep the runtime foundation steady: Dingo now aligns build, test, publish, and module tooling on current supported components so day to day operation stays more consistent.

Corrected stop chain reads when callers cancel work: Dingo now stops these reads promptly when the calling process cancels the request, which makes long running work easier to control.
Fixed keep database state aligned with the selected network: Database operations now carry the active network setting more consistently, which helps nodes avoid mismatched database behavior.
Resolved preserve Postgres epoch summaries during database activity: Postgres installations now keep epoch summary readiness intact more consistently, which makes snapshot state more dependable.
Strengthened retain missing transaction results during recovery: Database imports now preserve missing transaction results and collateral returns more reliably during recovery.
Refined return clearer transaction submission failures: Dingo now preserves valid rejection details so transaction failures are easier to understand and handle.
Stabilized surface chain sync send failures sooner: Dingo now reports send failures through connection close events so broken sessions are easier to detect.
Streamlined trim retained header history during sync: Dingo now removes excess retained header history during normal sync work, which helps long running nodes stay steadier over time.

Thank you for trying!
