Release 45 - 2025-08-11
This is an optional release that enhances chunk broadcasting with improved preferred peer management, adds a hash-based partitioning filter for distributed data processing, fixes ArNS basename cache refresh issues, and includes comprehensive documentation improvements with a new glossary of AR.IO Node terminology.
Added
- Added hash partitioning filter (
MatchHashPartition) for distributing transaction and data item processing across multiple nodes with configurable partition ranges - Added comprehensive glossary documentation covering AR.IO Node terminology, concepts, and architectural components
Changed
- Improved chunk broadcasting preferred peer management with doubled default per-node queue depth threshold and ensured preferred peers are always prioritized first
- Enhanced circuit breaker metrics with more detailed labels for better monitoring of data source failures
- Improved ArNS resolution to properly propagate 404 errors from trusted gateway resolution (a more complete fix is coming in the next release)
- Expanded OTEL tracing to include ArNS cache operations for improved observability of name resolution and cache hydration
Fixed
- Fixed unreliable ArNS basename cache refreshes by adding retry logic for pagination failures and replacing p-debounce with timestamp-based debouncing for more predictable behavior
- Fixed undefined headers handling in data requests
- Fixed invalid cache hits by ensuring base64url encoded IDs are properly validated before use
- Fixed routes data handling for undefined IDs in validity checks
