Summit week delivered a cluster of production features, agent-infrastructure launches, and a stable Rover CLI.

**Rover 1.0 replaces static API keys with OAuth.** The 1.0 release rebuilds auth, configuration, extensibility, and checks/publish around how teams run Rover today — in local development, CI, and agentic tooling. The `rover subgraph check` JSON output also gains per-contract-variant detail, with `json_version` moving to `"3"`.

**GraphOS Router 3.0 starts up without the management plane.** Released in Preview at Summit, 3.0 packages persisted queries into Graph Artifacts so routers can start without reaching Apollo's management plane. A new query planner with bounded memory usage replaces the existing algorithm. Native circuit breaking and a rewritten request pipeline ship alongside it.

**Apollo Connectors v0.4 is generally available.** Teams can now express abstract types (interfaces and unions), inline `->` transforms, and connectors that return data without an HTTP request — all declared directly in schema with no resolver code or subgraph server.

**GraphOS Agent Services governs API access for agents.** Announced at Summit, it addresses MCP credential sprawl: a central layer manages tool definitions, credentials, and what data returns to agent context — limiting field exposure without modifying upstream APIs.

**Apollo Client 4.3 ships custom scalar support.** The most-requested feature lands in 4.3 alongside type-safe cache access and improved TypeScript ergonomics for incremental data. Patch releases through 4.3.3 follow, including a deferred-fragment memory leak fix.

**Apollo Kotlin 5.2.0 adds the HTTP QUERY method and empty selection sets**, rounding out the window's mobile-SDK updates.
