API Gateway v3.0 is now generally available. This is a major release with breaking changes — see the migration guide before upgrading.

Performance

The routing layer was rewritten in Rust. Throughput increased from 80K to 340K requests/second per node. p99 latency dropped from 12ms to 3ms.

GraphQL support

v3 includes a native GraphQL proxy that understands GraphQL semantics — rate limiting by operation complexity, caching by operation hash, and query depth limiting.

Policy engine

The new policy engine uses a Rego-based language (compatible with OPA) for expressive, testable routing and auth policies. Write unit tests for your gateway policies just like any other code.
