-## What's new in v1.2.1-beta.18
+## What's new in v1.3.0
 
-### Bug fixes
+### Multi-org support
-- Replaced callAsyncJavaScript fetch approach with WebKit navigation: instead of running `fetch()` in the page's JS context (which was returning 401 because it bypasses the SPA's auth interceptors), each API call now navigates the WebView to the API URL directly. WebKit sends full browser headers and cookies automatically at the HTTP layer, the same way a real browser navigation works. This is more reliable regardless of what server-side auth mechanism claude.ai uses.
+- App now uses the `lastActiveOrg` cookie to identify which organisation is active, matching exactly what the claude.ai frontend does. Previously the app always picked the first org returned by bootstrap, which is the personal "Individual Org" for users with multiple organisations — causing persistent 403 errors on all usage endpoints.
-- API calls are now sequential to share a single WebView for all navigations
+- Plan label (e.g. **Max**, **Pro**, **Team**) now reads capabilities from the active org, not the first membership.
-- Added redirect detection: if WebKit follows a 302 to /login, the response is treated as an auth failure rather than returning HTML to the JSON parser
 
-## What's new in v1.2.1-beta.17
+### Reliable API access via WebView
+- All API calls now run through `WKWebView.callAsyncJavaScript`, making real same-origin browser requests instead of URLSession. Claude.ai's org-specific endpoints reject native HTTP clients (403) even with correct cookies and headers; running inside the browser context passes all server-side checks.
+- A background WebView is created at startup when session cookies are detected, so usage data loads immediately without requiring a manual sign-in.
 
-### Bug fixes
+### Diagnostics
-- Fixed "Not signed in" after login by adopting the login WebView directly for API calls
+- New **Diagnostics** panel in Settings shows cookie store, last API request/response, bootstrap body, and the `lastActiveOrg` cookie value — making it easy to report issues.
-- Added diagnostic error messages for JS errors and unexpected responses
-
-## What's new in v1.2.1
-
-### Bug fixes
-- Fixed WebKit suspending the background WKWebView: anchored in a transparent 1×1 NSWindow
-- Fixed login window auto-closing before sign-in completes
-- Added /api/organizations as a final fallback for org ID resolution
-- Fixed Settings incorrectly showing "Signed in" after a failed refresh

   "notes": "## What's new in v1.2.1-beta.18\n\n### Bug fixes\n- Replaced callAsyncJavaScript fetch approach with WebKit navigation: instead of running `fetch()` in the page's JS context (which was returning 401 because it bypasses the SPA's auth interceptors), each API call now navigates the WebView to the API URL directly. WebKit sends full browser headers and cookies automatically at the HTTP layer, the same way a real browser navigation works. This is more reliable regardless of what server-side auth mechanism claude.ai uses.\n- API calls are now sequential to share a single WebView for all navigations\n- Added redirect detection: if WebKit follows a 302 to /login, the response is treated as an auth failure rather than returning HTML to the JSON parser\n\n## What's new in v1.2.1-beta.17\n\n### Bug fixes\n- Fixed \"Not signed in\" after login by adopting the login WebView directly for API calls\n- Added diagnostic error messages for JS errors and unexpected responses\n\n## What's new in v1.2.1\n\n### Bug fixes\n- Fixed WebKit suspending the background WKWebView: anchored in a transparent 1×1 NSWindow\n- Fixed login window auto-closing before sign-in completes\n- Added /api/organizations as a final fallback for org ID resolution\n- Fixed Settings incorrectly showing \"Signed in\" after a failed refresh"
