✨ Highlights

Improved add a configurable multi active header sync strategy: Dingo can now sync headers through a configurable multi peer strategy, which gives operators more control over how header sync progresses.
Expanded complete transaction builds with node state queries: Dingo now completes more transaction build flows through node state queries, which improves support for locally assembled transactions.
Refined add dedicated configuration and startup support for related services: Dingo now exposes dedicated configuration and startup handling for related services, which makes them easier to configure and start.
Enhanced recognize credential tags across stake and governance identities: Dingo now handles tagged stake and governance identities more accurately, which keeps identity driven actions aligned with the intended credentials.
Strengthened apply pool reap refunds at epoch boundaries: Dingo now returns pool reap refunds at the correct epoch boundaries, which keeps pool related ledger accounting aligned with network events.
Improved sync governance era transaction donations into treasury: Dingo now moves supported transaction donations into treasury accounting, which keeps treasury totals aligned with donation activity.
Expanded apply certificate transfer effects to rewards and accounting pools: Dingo now applies certificate driven balance transfers across rewards and accounting pools, which keeps ledger balances aligned with those changes.
Refined remove orphaned governance actions after enactment: Dingo now removes orphaned governance actions after enactment and returns their deposits, which keeps governance state and related accounting accurate.
Enhanced align transaction detail responses with current client expectations: Dingo now returns transaction detail data in a shape that matches current client expectations more closely, which improves compatibility for applications that read detailed transaction records.
Strengthened surface hard misses when looking up blocks by hash: Dingo now reports block by hash misses more clearly and records them in metrics, which makes lookup failures easier to detect and monitor.
Improved speed up block cache access with sharded storage: Dingo now serves cached blocks through sharded storage, which improves cache responsiveness under heavier access patterns.
Expanded recover from stale peers with steadier reconnect behavior: Dingo now handles stale peers with steadier reconnect timing, which helps sync recover more cleanly after peer health drops.

💪 Improvements

Refined keep header sync behavior configurable across active peers: Dingo now lets operators tune how active peers participate in header sync, which makes sync behavior easier to adapt to different environments.
Enhanced cover more transaction build data through node queries: Dingo now resolves more transaction build inputs through node queries, which reduces gaps in transaction construction workflows.
Strengthened prepare related services through a dedicated configuration section: Dingo now groups related service settings in a dedicated configuration section, which makes setup easier to manage.
Improved start related services through the main startup flow: Dingo now starts related services through the main startup flow, which keeps service initialization more consistent.
Expanded preserve stake identity behavior across credential forms: Dingo now keeps stake identity handling consistent across supported credential forms, which improves reliability for stake based operations.
Refined preserve governance identity handling across credential forms: Dingo now keeps governance identity handling consistent across supported credential forms, which improves reliability for governance related actions.
Enhanced return pool deposits through the expected refund path: Dingo now routes pool deposit refunds through the expected ledger path, which keeps refund handling easier to reconcile.
Strengthened record treasury changes from donations during transaction processing: Dingo now records donation driven treasury changes during transaction processing, which keeps treasury tracking more complete.
Improved reflect certificate transfer adjustments in reward balances: Dingo now reflects certificate driven adjustments directly in reward balances, which keeps reward totals more accurate.
Expanded reflect certificate transfer adjustments across accounting pools: Dingo now reflects certificate driven adjustments across accounting pools, which keeps pool balances aligned with ledger events.
Refined clear enacted governance actions that no longer remain active: Dingo now clears enacted governance actions that no longer remain active, which keeps governance state easier to interpret.
Enhanced return deposits from orphaned governance actions: Dingo now returns deposits from orphaned governance actions when they fall out of use, which keeps related balances accurate.
Strengthened align transaction detail fields across response data: Dingo now aligns more transaction detail fields across response data, which reduces mismatches for applications that depend on exact field values.
Improved make missing block lookups easier to observe: Dingo now makes missing block lookups easier to observe through clearer reporting and metrics, which improves operational visibility.
Expanded scale cache lookups more evenly under concurrent access: Dingo now spreads cache lookups more evenly under concurrent access, which helps block retrieval stay responsive.
Refined pace reconnect attempts after peer staleness: Dingo now spaces reconnect attempts more effectively after peer staleness, which reduces avoidable churn during recovery.
Enhanced recover sync progress after stale peer disconnects: Dingo now restores sync progress more reliably after stale peer disconnects, which helps the node resume forward progress sooner.
Strengthened keep reconnect backoff behavior more consistent across retries: Dingo now keeps reconnect backoff behavior more consistent across retries, which makes peer recovery steadier.

🔧 Fixes

Corrected apply refund timing at the proper epoch boundary: Dingo now applies refund timing at the proper epoch boundary, which prevents pool related refunds from landing at the wrong point in ledger processing.
Fixed carry treasury donations into ledger totals: Dingo now carries treasury donations into ledger totals correctly, which prevents treasury balances from missing donation activity.
Resolved apply certificate transfer effects to the correct balances: Dingo now applies certificate transfer effects to the correct balances, which prevents reward and pool totals from drifting from ledger events.
Repaired remove obsolete governance actions after enactment: Dingo now removes obsolete governance actions after enactment, which prevents outdated governance records from lingering.
Corrected match transaction detail responses more closely to expected output: Dingo now matches transaction detail responses more closely to expected output, which prevents clients from handling unexpected response differences.

🧪 Testing, CI, Docs, and Release Tooling

Updated add test coverage for multi peer header sync behavior: Validation now covers multi peer header sync behavior more thoroughly, which improves confidence in configurable sync flows.
Expanded verify transaction build node query behavior in tests: Validation now verifies node query behavior across transaction build flows, which improves confidence in transaction construction results.
Refined cover related service configuration and startup paths in validation work: Validation work now covers related service configuration and startup paths more directly, which helps catch setup regressions earlier.
Enhanced test tagged identity handling across supported cases: The test suite now exercises tagged identity handling across more supported cases, which improves confidence in stake and governance identity behavior.
Strengthened test pool refund handling around epoch transitions: The test suite now checks pool refund handling around epoch transitions, which improves confidence in ledger accounting at boundary events.
Improved test treasury donation accounting during transaction processing: The test suite now checks treasury donation accounting during transaction processing, which improves confidence in treasury totals.
Expanded test certificate transfer effects across rewards and accounting pools: The test suite now checks certificate transfer effects across rewards and accounting pools, which improves confidence in balance updates.
Refined test governance cleanup after enactment: The test suite now checks governance cleanup after enactment, which improves confidence that inactive actions and deposits clear correctly.
Enhanced publish the v0.55.0 release notes page: The release history now includes the v0.55.0 notes, which keeps the published record current.
