New

• WebSocket Transport: Apollo iOS 2.0 now supports WebSocket connections using the graphql-transport-ws protocol for subscriptions, queries, and mutations. See the WebSocket Transport documentation for setup and usage details.
• ApolloURLSession delegate injection (#899): Added support for injecting a custom URLSessionTaskDelegate into ApolloURLSession, enabling delegate callback handling. Thank you to @hammy-e for the contribution.
• Make JSONRequest.useGetForQueries mutable (#897): The useGetForQueries property on JSONRequest is now a var, allowing interceptors to mutate the request directly instead of copying it. Thank you to @nevil for the contribution.

Fixed

• Add preflight HTTP header for CSRF prevention (#900): Added the X-Apollo-Operation-Name header to requests to satisfy Apollo Router's CSRF prevention requirements.

Improved

• Use dictionary for objectType(forTypename:) lookup (#918): Replaced the generated switch statement in SchemaMetadata.objectType(forTypename:) with a static dictionary lookup, improving deserialization performance by ~75% for schemas with many types (4000+). Thank you to @erneestoc for the contribution.
