+- ⚠️ [Breaking] Removes `ShopifyApp::JWTMiddleware`. Any existing app code relying on decoded JWT contents set from `request.env` should instead include the `WithShopifyIdToken` concern and call its respective methods. [#1861](https://github.com/Shopify/shopify_app/pull/1861)
+  - Impacted values:
+    - `request.env["jwt.token"]`
+    - `request.env["jwt.shopify_domain"]`
+    - `request.env["jwt.shopify_user_id"]`
+    - `request.env["jwt.expire_at"]`
 - Handle scenario when invalid URI is passed to `sanitize_shop_domain` [#1852](https://github.com/Shopify/shopify_app/pull/1852)
