-## What's new
+## What's new in beta.20
 
-Initial Windows release.
+- Fixed: app now correctly shows you as signed in after login
+- Fixed: org ID is fetched from API rather than hardcoded; tries multiple JSON paths
+- Fixed: auth check now uses HTTP 200 from bootstrap (not whether org ID was found)
+- Added browser User-Agent header so API responds correctly
