Developer Release Notes

The Docs, Sheets, and Slides MCP servers in Developer Preview can now read comments via an optional commentsIncluded field and create, reply to, resolve or reopen, update, and delete comments and replies through their update tools. The servers also added writeControl revision fields, field masks, inline batchUpdate request schemas, a new read_slide_page and read_slide_page_thumbnail tool, and expanded tool annotation definitions.

The Google Docs API is generally available for programmatically reading, creating, and managing comments and suggestions, including writing edits as suggestions via writeControl.writeMode set to SUGGEST and accepting, rejecting, or deleting suggestion threads. The Sheets and Slides APIs are also generally available for reading, creating, and managing comment threads and replies.

Two new fields on the Space resource, accessSettings.accessPermissionSettings.viewSpaceMembershipSetting and permissionSettings.viewSpaceMembership, let developers define which Workspace target audiences and space roles can view a space's member list. Requests that modify membership visibility must include both fields in the updateMask and request body.

Extending Google Workspace Studio with add-ons is now generally available, with custom starters defined as workflowTriggers in the API and add-on manifest so apps and services can notify Studio when events occur and initiate workflow executions. The Workspace Studio API is also available for third-party services and webhooks to fire triggers.

The Google Chat API message pin endpoints are now generally available and no longer restricted to the Developer Preview Program, letting developers programmatically pin, unpin, and list pinned messages in a Chat space.

The Google Workspace Marketplace SDK is now generally available with prompts to sync draft changes when host products are added or removed in a deployment's manifest. New host products appear as "Unsaved" in the App Integrations section of the App Configuration tab, and that tab now shows published status (Unsaved, Draft, Under review, or Published) for each supported host product.

Apps Script now supports Workspace data regions, storing project files, code, manifests, trigger metadata, and key-value storage in the designated geographic region and processing script executions there. Available on Enterprise Plus and Frontline Plus (storage and processing) and Education Standard and Education Plus (storage only); legacy Rhino runtime projects must migrate to V8 to run under strict data region policies.

The Meet API spaces.members resource is now generally available, letting developers manage meeting space members and assign co-host roles before or during a meeting. The resource exposes create, delete, get, list, patch, and batchUpdate methods.

The Meet API spaces.members resource is now generally available, letting developers manage meeting space members and assign co-host roles before or during a meeting.

The Google Chat API now supports adding inline citations and footer sources to text messages, available as a developer preview. Citations work with messages using MARKUP_SYNTAX_MARKDOWN and created asynchronously via the API.

Message actions in Google Chat are now generally available, letting users invoke your Chat app from the message context menu. Works for both Google Chat apps and Google Workspace Add-ons that extend Chat.

You can now format Google Chat messages using standard Markdown syntax by setting the markupSyntax field to MARKUP_SYNTAX_MARKDOWN when creating a message via the Chat API.

The spaces.search method of the Chat API is now generally available, allowing users to manage and search for spaces they are members of without administrator privileges.

The Gemini side panel in the Apps Script editor can generate, modify, and debug code using context from the active script project.
