- Update this library to support the upcoming release of AWS Lambda Runtime for Swift v2. This change affects the public API (some `Sendable` added) and requires a major version bump. I propose to release v2 to align this library's major with the Swift AWS Lambda Runtime's major. - Add a QuoteAPI example in the `Examples` directory
