JS SDK
The SDK shipped v5.0.0 in early March with breaking changes, then stabilized through patch releases. The major version introduced structural changes documented in a migration guide, while subsequent releases fixed langchain integration issues—particularly around structured input handling in chain start events and content type checking in prompt clients—and added an option to disable logging entirely. Recent patches also synced API spec updates and addressed media handling in OpenTelemetry integration with AI SDK FilePart data.
The SDK shipped v5.0.0 as a major version bump with breaking changes requiring migration; see the upgrade documentation for details. Before the stable release, a beta landed fixes for OpenTelemetry's FilePart data handling in AI SDK media workflows and aligned the API spec with upstream changes.
