Apollo Router v1.0 has officially reached version 1.0, offering a lighter and faster supergraph runtime written in Rust. The release expands its capabilities to support even more use cases with optimizations for client app performance, hardened security, and robust extensibility. Entity-based `@defer` support allows apps to access essential data with minimal latency while deferring less critical data, improving performance benchmarks like first-content-paint (FCP), time-to-interactive (TTI), and total-blocking-time (TBT). Apollo Router now supports cross-site forgery protection, subgraph error redaction, and disabling introspection for enhanced security. The release also includes enhanced extensibility with a new stable v1 configuration schema, full support for Rhai scripting, and native extensions that can be used via standard YAML config and Rhai scripting. Stock router binaries and docker images are available for Linux, Mac, and Windows, along with pre-built docker images and an updated Helm chart for Kubernetes deployments.
