## Agent Summary
Vercel AI SDK release 7.0.120 introduces two bug fixes: preserving tool metadata from tool output chunks (b032d70) and continuing active UI message parts when resuming after a disconnect (e21b98b). It also updates the @ai-sdk/gateway dependency to 4.0.98.

Vercel AI SDK version 7.0.120 includes patch changes addressing stream handling and state continuity. Commit b032d70 fixes an issue where tool metadata was lost from tool output chunks.
