New useWindowTitle hook and bugfixes

This release introduces a new useWindowTitle hook, opt-in dev-mode telemetry, and several reliability improvements across authentication and document handling.

Use the new useWindowTitle hook to manage browser tab titles from your components. Pass it a string, and it sets the document title for the active tab.

import { useWindowTitle } from '@sanity/sdk-react'

function MyComponent() {
  useWindowTitle('My Custom Title')
  return <div>Content</div>
}

View the reference documentation for more details.

The SDK now supports consent-gated telemetry in development mode. Telemetry only activates after you explicitly opt in, is fully tree-shaken from production builds, and never affects SDK functionality. No queries, document IDs, or field names are collected. You can configure your telemetry settings in manage.

• Fixed Studio mode cookie authentication when the token source emits null.
• Fixed an issue where onSubscribe sometimes skipped legitimate first state changes in createStateSourceAction.
• Prevented unnecessary token refreshes by correctly initializing lastTokenRefresh for stamped tokens.
• Prevented cleanup timers from keeping Node.js processes alive.
• Live-edit documents now use the mutations endpoint, so edits no longer create drafts.
• Fixed an issue where useEditDocument and useApplyDocumentActions created drafts instead of working against a content release version. Use the perspective option to target a specific release:

import { useEditDocument } from '@sanity/sdk-react'

function EditArticleInRelease({documentId}: {documentId: string}) {
  // Use the document's plain ID, not `versions.<releaseName>.<id>`.
  // Add the document to a release first with `createDocument` if needed.
  const editArticle = useEditDocument({
    documentId,
    documentType: 'article',
    perspective: {releaseName: 'rxV176dy'},
  })

  return (
    <button onClick={() => editArticle(prev => ({...prev, title: 'Updated for release'}))}>
      Edit in release
    </button>
  )
}
