Developers can now fine-tune real-time search behavior using the new SearchAsYouTypeSpec fields. By specifying a list of fields (with individual key and weight overrides) and a scoreThreshold, you can control which indexed fields influence scoring and filter out low-relevance results on a per-request basis. Additionally, the new resourceAccessControlConfig allows projects to enforce resource-level IAM permissions for Gemini Enterprise users, ensuring they only interact with data stores they are explicitly authorized to access.
Breaking Change: The family field within WidgetConfig.UiSettings.ModelConfigInfo.ResolvedModel is now marked as readOnly. This field, used to group models in the UI selector, is now immutable for API consumers. In the v1alpha surface, support was also added for UserSuppliedSobiArtifactReference to handle file attachments linked to long-running agent tasks.
