+
+Added `organizationSyncOptions` option to `clerkMiddleware()`. It's used to activate a specific organization or personal account based on URL path parameters.
+
+Usage:
+
+```ts
+// app/root.tsx
+export const middleware: Route.MiddlewareFunction[] = [
+  clerkMiddleware({
+    organizationSyncOptions: {
+      organizationPatterns: [
+        '/orgs/:slug', // Match the org slug
+        '/orgs/:slug/(.*)', // Wildcard match for optional trailing path segments
+      ],
+    }
+  })
+]
+```
+
+To learn more about best practices for using organization slugs to manage the active organization, check out this [guide](https://clerk.com/docs/organizations/org-slugs-in-urls).
