We now use 🌿 Fern to generate our Go SDK. While this releasing has breaking changes, it comes with several quality of life upgrades:

• Endpoint coverage: All endpoints that are supported in our Node SDK are
  now also supported in Go.
• Resource-scoped SDK methods: Endpoints are scoped under their resource. For
  example, instead of courier.DeleteBrands the SDK now reads courier.Brands.Delete(...)
• Docs on Hover: All endpoint and parameter level documentation that you see
  on our docs website are now embedded directly within the SDKs.
• Strongly Typed: The SDK now contains types for all of our modles -- including
  complex unions like ContentMessage and TemplateMessage.
• Retries with Exponential Backoffs: The SDK now supports retries with exponential
  backoff.
