Upyo 0.2.0 has been released, introducing new features to this cross-runtime email library that supports Node.js, Deno, Bun, and edge functions. The latest version expands its capabilities with Amazon SES transport support, enabling AWS Signature v4 authentication and session-based authentication. Additionally, comprehensive OpenTelemetry integration has been added, offering distributed tracing, metrics collection, and error classification without altering existing code. The OpenTelemetry transport automatically instruments email operations, tracking delivery rates and latency, and integrates with existing OpenTelemetry infrastructure. Community feedback is encouraged to further improve Upyo, whether through testing the new Amazon SES transport, implementing OpenTelemetry, or contributing to the GitHub repository. This release enhances Upyo's utility by providing more transport options and robust observability features, making it a valuable tool for developers needing reliable email sending across various environments.
