 ## What's new in v1.2.1
 
 ### Bug fixes
-- Fixed a timing race in the background API WebView — `refresh()` now correctly waits for the WebView to finish loading before making API calls, preventing silent failures on startup
+- Fixed the root cause of "Not signed in" after being clearly signed in: claude.ai's auth requires credentials beyond plain HTTP cookies (localStorage tokens, Service Worker state, etc.) that URLSession cannot access. All API calls now run via callAsyncJavaScript inside a background WKWebView, using the same fetch path the page itself uses — credentials are included automatically.
-- Fixed usage data not loading after sign-in — API calls now run inside a persistent background WebView using the page's own fetch(), so all credentials (cookies, httpOnly tokens, etc.) are included automatically
+- Fixed WebKit suspending the background WKWebView: a WKWebView with no window is throttled/suspended by macOS, preventing JS execution. The background WebView is now anchored in a transparent 1×1 NSWindow, keeping it active.
-- Fixed "Not signed in" showing after login — the background WebView is now reloaded after sign-in to pick up the new session before the first data refresh
+- Fixed login window auto-closing before sign-in completes — login window loads `/login` and only detects auth when back on claude.ai (not on OAuth provider redirects)
-- Fixed "Not signed in" showing incorrectly on launch when the session was already active
+- Added `/api/organizations` as a final fallback for org ID resolution
-- Sign-in state is now detected immediately from stored cookies on startup, before the first data refresh completes
+- Fixed Settings incorrectly showing "Signed in" after a failed refresh
-- Fixed login window auto-closing before the user could sign in — the login window now correctly loads the `/login` page so it only detects auth after the actual sign-in redirect
-- Fixed "No API key configured" showing after signing out — now correctly shows "Not signed in" with a prompt to sign in
-- Added `/api/organizations` as a final fallback for org ID resolution when the bootstrap API response doesn't include it
-- Fixed Settings incorrectly showing "Signed in" after a failed refresh — sign-in state now resets when authentication fails
-- Rewrote login detection to use KVO on the WebView URL — correctly detects auth for Next.js SPA navigation (history.pushState) that doesn't trigger didFinish

+  "notes": "## What's new in v1.2.1\n\n### Bug fixes\n- Fixed the root cause of \"Not signed in\" errors: URLSession was silently discarding the manually-set Cookie header because `httpShouldHandleCookies` defaults to `true`, which makes URLSession replace it with its own (empty) HTTPCookieStorage — claude.ai session cookies live in WKWebsiteDataStore, not HTTPCookieStorage. Setting `httpShouldHandleCookies = false` ensures the cookies are actually sent.\n- Added browser-like request headers (User-Agent, Origin, Referer) matching what Claude's API expects, consistent with the working Windows implementation\n- Removed background WKWebView complexity added in beta.12–13 — reverted to simple URLSession approach with correct cookie handling\n- Fixed login window auto-closing before the user could sign in — login window loads `/login` so auth is only detected after the actual sign-in redirect\n- Fixed login detection for Next.js SPA navigation using KVO on WebView URL (history.pushState doesn't trigger didFinish)\n- Added `/api/organizations` as a final fallback for org ID resolution\n- Fixed Settings incorrectly showing \"Signed in\" after a failed refresh"
