What's new: Google Cloud made citation_mappings generally available for Gemini Enterprise custom MCP data stores, enabling source citation chips in tool-grounded answers.

What it means for my business: Teams can expose the source behind answers from proprietary systems, making agent outputs easier to review, audit, and manually validate.

What's new: OpenAI added content controls for eligible real-time Google Drive, Microsoft Teams, and Outlook access, plus centralized external-access settings in ChatGPT Enterprise.

What it means for my business: Administrators can set organization and app-specific permissions, review connected users, and disable access to limit overbroad enterprise-content retrieval.

What's new: Gemini Enterprise Workflow Builder can now connect to Confluence Data Center and Jira Data Center to search data and automate actions.
