Vendor-reportedChecked: [release]

Published: · Event date:

TanStack announced AI 1.0 on October 23, committing to stable APIs across 76 packages. The new harness for ongoing agent sessions is an exception: its packages and integration entry points remain experimental. Existing chatbot deployments need a coordinated client, server and saved-data migration.

Vendor-reportedChecked: [release][upgrade]

What changes for users

Support-bot teams should inventory pending approvals and saved conversations before switching versions. Test rejection, expiry, transport failure and reload recovery in staging; do not equate the new API with permission to bypass approvals.

The release removes deprecated 0.x APIs whose replacements were already available. Clients and servers must move together. Tool approval remains supported, but approval handlers now resolve AG-UI interrupts instead of calling the removed addToolApprovalResponse method.

Vendor-reportedChecked: [release][upgrade][interrupts]

The interrupt guide warns that 1.0 cannot resume runs paused on 0.x. The saved-data guide also requires handling pending interrupts and older record formats before deployment. A stable release label therefore does not mean an existing conversation can survive an unchanged upgrade.
