Developer Release Notes

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.
