Rendezvous WebSockets get lower latency and safer tracing
Codex disabled Nagle on Rendezvous WebSockets and stopped emitting full-text WebSocket traces.
The release focuses on transport behavior: small WebSocket messages should avoid Nagle-related delay, while tracing no longer records complete message text.
Alpha release context: 1 official tag was published that UTC day (rust-v0.143.0-alpha.32). The full comparison contains 4 commits and 6 changed files.
Evidence
Rendezvous WebSockets disable Nagle's algorithm.Why it matters: Small interactive messages can be sent without waiting for TCP packet coalescing, reducing one source of latency.
