WebSocket liveness, multi-agent messaging, and XML security tighten up
The release bounded Rendezvous liveness, consolidated multi-agent sends, fixed Bedrock metadata, and addressed quick-xml advisories.
Reliability and security dominate this window. Network liveness gets a bound, multi-agent communication gets one send path, and a vulnerable XML dependency is updated.
Alpha release context: 2 official tags were published that UTC day (rust-v0.143.0-alpha.33, rust-v0.143.0-alpha.34). The full comparison contains 10 commits and 38 changed files.
