## sol-trade-sdk v4.0.2
|
|
|
|
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 address` when 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`
|
|
- 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).
