Google permanently removed the legacy Gemini Interactions API schema on June 8.
Story
The v1beta Interactions schema is gone, replaced by a structured "steps" timeline and a polymorphic "response_format," enabling future mid-flight steering and async tool calls. Developers who hadn't opted into the new revision header now face hard breakage. A dated, real migration deadline for anyone building agents on Gemini. Two breaking changes from Apple and Google in one day. Tax season for platform dependencies.
