April 2025 (2025-04) — Delivered API ergonomics and streaming reliability improvements for starfederation/datastar, focusing on business value and maintainable architecture. The Merge Fragments API was enhanced to accept a single string input and to support objects implementing the __html__ protocol by converting them to HTML strings before processing, simplifying client usage and data rendering. SSE framework improvements introduced a dedicated ServerSentEventGenerator, enabling Datastar to use the generator directly, and included header hygiene to prevent compatibility issues in downstream clients. These changes reduce integration friction, improve real-time capabilities, and align with Python SDK conventions.
