Key updates include first-class support for streaming media types (text/event-stream, application/jsonl) with schema definitions for individual stream items, hierarchical tag organization for better API navigation, support for extended HTTP methods including the QUERY method through additionalOperations, clarified path templating semantics for consistent routing across tools, clearer example semantics distinguishing data-level from serialized representations, and explicit OAuth 2.0 Device Authorization Flow support. These changes standardize patterns that previously required vendor extensions, making the specification more expressive for modern API designs while maintaining backward compatibility. ## Full article daily.dev links to this article rather than hosting it.
