 - **Rspack Support**: Added `--rspack` flag to `react_on_rails:install` generator for significantly faster builds (~20x improvement with SWC). Includes unified webpack/rspack configuration templates and `bin/switch-bundler` utility to switch between bundlers post-installation.

-- **Shakapacker 9.1.0 Upgrade**: Upgraded Shakapacker from 9.0.0 to 9.1.0. This minor version update includes bug fixes and improvements. Updated webpack configuration in Pro dummy apps to use forEach pattern for better compatibility with multiple SCSS rules.

-- **Shakapacker 9.2.0 Upgrade**: Upgraded Shakapacker from 9.1.0 to 9.2.0. This minor version update adds a new `bin/shakapacker-config` utility for debugging webpack/rspack configurations with doctor mode, save mode, and stdout mode options. Supports YAML, JSON, and Node.js inspect output formats. by [justin808](https://github.com/justin808).
-
-- **Removed Pro Warning Badge**: Removed the visual warning badge that appeared when non-Pro users attempted to enable Pro-only features like `immediate_hydration`. Pro features are now silently disabled when a Pro license is not available, providing a cleaner user experience without intrusive warning banners. [PR #1993](https://github.com/shakacode/react_on_rails/pull/1993) by [AbanoubGhadban](https://github.com/AbanoubGhadban).
-
 - **`immediate_hydration` now automatically enabled for Pro users**: The `config.immediate_hydration` configuration option has been removed. Immediate hydration is now automatically enabled for React on Rails Pro users and disabled for non-Pro users, simplifying configuration while providing optimal performance by default. Component-level overrides are still supported via the `immediate_hydration` parameter on `react_component`, `redux_store`, and `stream_react_component` helpers. [PR 1997](https://github.com/shakacode/react_on_rails/pull/1997) by [AbanoubGhadban](https://github.com/AbanoubGhadban).
 
 - **`generated_component_packs_loading_strategy` now defaults based on Pro license**: When using Shakapacker >= 8.2.0, the default loading strategy is now `:async` for Pro users and `:defer` for non-Pro users. This provides optimal performance for Pro users while maintaining compatibility for non-Pro users. You can still explicitly set the strategy in your configuration. [PR #1993](https://github.com/shakacode/react_on_rails/pull/1993) by [AbanoubGhadban](https://github.com/AbanoubGhadban).

+- **Node Renderer Configuration**: Renamed `bundlePath` configuration option to `serverBundleCachePath` in the node renderer to better describe its purpose and avoid confusion with Shakapacker's public bundle path. The old `bundlePath` option continues to work with deprecation warnings. Both `RENDERER_SERVER_BUNDLE_CACHE_PATH` (new) and `RENDERER_BUNDLE_PATH` (deprecated) environment variables are supported. [PR #2008](https://github.com/shakacode/react_on_rails/pull/2008) by [justin808](https://github.com/justin808).
+
+#### Fixed
+
+- **Node Renderer Worker Restart**: Fixed "descriptor closed" error that occurred when the node renderer restarts while handling an in-progress request (especially streaming requests). Workers now perform graceful shutdowns: they disconnect from the cluster to stop receiving new requests, wait for active requests to complete, then shut down cleanly. A configurable `gracefulWorkerRestartTimeout` ensures workers are forcibly killed if they don't shut down in time. [PR 1970](https://github.com/shakacode/react_on_rails/pull/1970) by [AbanoubGhadban](https://github.com/AbanoubGhadban).
