Google Workspace developer release notes

Generally Available: The Google Chat API endpoints targeting message pins are now Generally Available (GA) and are no longer restricted to the Developer Preview Program. Developers can use the Chat API to programmatically pin messages, unpin messages, and list all pinned messages within a Google Chat space.

For more details, see Pin or unpin messages in Google Chat spaces and the REST reference documentation:

• spaces.messagePins.create
• spaces.messagePins.delete
• spaces.messagePins.list

Generally Available: The Google Workspace Marketplace SDK now prompts developers to sync draft changes when host products are added or removed in a deployment's manifest. New host products appear in the App Integrations section of the App Configuration tab with a status of "Unsaved". After saving changes as a draft, developers can submit the draft for review on the Store Listing tab before publishing the new host product to their Google Workspace Marketplace listing. Additionally, the App Configuration tab now displays the published status (Unsaved, Draft, Under review, or Published) for each supported host product. To learn more, see Update your app listing with drafts and Identify how your app integrates with Google Workspace applications.

Generally Available: Apps Script now supports data regions in Google Workspace, adhering to organizational data location policies configured in the Google Admin console:

• Data at rest: Script project files, code definitions, manifest configurations, trigger metadata, and key-value storage (such as Property Service and Cache Service) are stored within the designated geographic region.
• Data processing: Script executions, container-bound automations, and associated runtime operations are processed within the selected region.

This feature is available for Google Workspace Enterprise Plus and Frontline Plus editions (in-region storage and processing), and Education Standard and Education Plus editions (in-region storage only). Scripts running on the legacy Rhino runtime are not supported under strict data region policies; projects must use the V8 runtime. For details on covered data and managing non-regionalized services, see What data is covered by a data region policy? and Set up advanced settings for data regions.

For more details, see the ACL resource documentation.

To ensure consistent visibility across recurring events, changing the visibility of a single instance in the Google Calendar API can affect all instances of the series:

• More restrictive changes propagate: If you change the visibility of one instance of a recurring event to a more restrictive setting (for example, from public to private), the change is propagated to all instances of the recurring event.
• Less restrictive changes are ignored: If you attempt to change the visibility of one instance of a recurring event to a less restrictive setting (for example, from private to public), the change is ignored and the visibility remains unchanged. To make a recurring event less restrictive, you must update the parent recurring event.

For more information, see Share calendars and events and the events resource reference.

Generally Available: The Google Calendar API now provides full support for custom labels and colors, allowing users to categorize events with a flexible palette beyond the previously fixed set of colors.
