February 2025: Implemented two major features for sanity-io/sdk with a focus on developer productivity, governance, and performance. Delivered a Document Store & Editing Hooks in the React SDK and a Document Permissions System, both designed to enhance end-to-end document workflows and security controls. The work includes robust state management, optimistic updates, enhanced synchronization status, and event handling to improve reliability and developer experience. Also refined useEditDocument to accept an updater function and to send only changed fields when no specific path is provided, reducing payloads and improving performance. No critical bug fixes were reported in this period; the emphasis was on delivering value through architecture and UX improvements that scale in enterprise contexts.
