-## What's new in beta.23
+## What's new in beta.27
 
-- About section now shows "vX.X.X available" label when an update is available (not just button label change)
+- Fix build error: use WebMessageAsJson (not WebMessageAsString) and post plain JS objects via postMessage
-- Sign-in: fixed app showing signed out after login window closes — cookies and cached auth now correctly set IsSignedIn=true
-- Sign-in: added brief delay before refresh so WebView2 user data folder is fully released by LoginWindow before reuse
-- Wider cookie domain filter (anthropic.com included alongside claude.ai)
-- Broader JS paths for email and org ID in bootstrap response
