ai@7.0.106
Vercel AI SDK 7.0.106 brings multiple bug fixes targeting stream handling, tool call serialization, cancellation behavior, and metadata tracking.
Why this signal matters
Version 7.0.106 of ai delivers a collection of patch fixes across streaming and agent tool lifecycles. Key fixes include: preserving provider metadata during simulated text streams; reporting the prepareStep model in streamed step results and using it for metadata fallbacks; preventing unhandled rejections on premature UI message stream termination; preserving prototype-named properties in tool outputs; retaining tool calls tied to pending approvals; properly closing telemetry spans when streams fail; canceling prompt attachment downloads upon call aborts or timeouts; and streaming structured output from final tool-loop steps alongside null and empty string JSON partials. It also updates dependencies on @ai-sdk/gateway and @ai-sdk/provider-utils.
Actionable summary
Vercel AI SDK patch release ai@7.0.106 resolves issues in multi-step and simulated text streaming, early stream abort/rejection handling, tool execution lifecycle (including approval retention and invalid tool call callbacks), JSON fence stripping, and telemetry span closing.
