This release focuses on QUIC reliability and low-latency submission stability for Astralane.
Highlights
- Fixed Astralane QUIC address-family mismatch that could produce
invalid remote addresswhen DNS returned IPv6 first and local endpoint was IPv4-only. - Added remote-family-aware local QUIC bind selection:
- IPv4 remote -> bind
0.0.0.0:0 - IPv6 remote -> bind
[::]:0
- IPv4 remote -> bind
- Added Astralane direct-IP candidate support (official region IPs), with IPv4-first selection for better QUIC stability.
- Added automatic endpoint failover and reconnect rotation across candidate addresses, reducing single-endpoint/DNS variance impact.
- Kept existing SDK interfaces compatible while improving submit-path resiliency.
Also included from recent updates
- BlockRazor gRPC endpoint fixes and gRPC default transport behavior improvements (v4.0.1).
- SWQOS transport path hardening and Binary-Tx response handling improvements (v4.0.0).
