v4.2.0

Generate custom scalars as inline classes with @map and @mapTo (#6404)

It is now possible to configure the adapters to use with scalars by using the @map directive:

extend schema @link(url: "https://specs.apollo.dev/kotlin_labs/v0.5/", import: ["@mapTo", "@map"])

extend scalar Date @map(to: "kotlinx.datetime.Instant", with: "com.apollographql.adapters.InstantAdapter")

If the to parameter is an inline value class, use the inlineProperty parameter to have the generated code box/unbox the value. In that case, with needs to point to an adapter of the underlying type:

extend scalar Timestamp @map(to: "com.example.Timestamp", with: "com.apollographql.apollo.api.LongAdapter", inlineProperty: "ts")

For the common cases where the scalar can be represented as a built-in Kotlin type (String, Boolean, Int, Long, Float, Double), you can use @mapTo and the compiler infers the adapter and generates an inline value class automatically:

extend scalar Length @mapTo(builtIn: Long)

Scalar definitions in schemas downloaded from introspection (#6389)

Downloading or converting an SDL schema from introspection now includes scalar definitions. This is required for clients to get a full view of the schema.

Support for @disableErrorPropagation

Apollo Kotlin now automatically adds @disableErrorPropagation if your server supports it and you opted in @catchByDefault in your schema extensions. This allows to use non-null types more liberally and still get support for partial data.
