What's shipped, and what's next.
Route matching, active health checks, connect retries, and a sandboxed WASM plugin hook shipped in 0.4; header rewriting, traffic mirroring, and mTLS shipped in 0.5; client-facing HTTP/2 and automatic HTTPS via ACME shipped in 0.6. In rough priority order from here: HTTP/3, HTTP/2 and TLS to upstreams, and a circuit breaker that ejects a flapping upstream faster than health checks alone. The config schema reserves fields for what's left, so configs written today keep working.
If one of these matters to you, open an issue: early-stage projects reorder roadmaps for real users. See the full CHANGELOG for release-by-release detail.
