 #### Added
 
 - **[Pro]** **Auto-resolve renderer password from ENV**: `setup_renderer_password` now falls back to `ENV["RENDERER_PASSWORD"]` when neither `config.renderer_password` nor a URL-embedded password is set, aligning Rails-side behavior with the Node Renderer defaults. Blank values (`nil` or `""`) are treated identically and fall through the full resolution chain: config → URL → ENV. [PR 2921](https://github.com/shakacode/react_on_rails/pull/2921) by [justin808](https://github.com/justin808).
+- **Interactive mode prompt for `create-react-on-rails-app`**: Running `npx create-react-on-rails-app` without `--pro` or `--rsc` now shows an interactive prompt to choose between Standard, Pro, and RSC modes (default: RSC recommended). Explicit flags skip the prompt, and non-interactive environments fall back to standard mode automatically. [PR 3063](https://github.com/shakacode/react_on_rails/pull/3063) by [justin808](https://github.com/justin808).
+- **[Pro] Configurable HTTP keep-alive timeout for node renderer connections**: Added `renderer_http_keep_alive_timeout` configuration option (default: 30s) to control how long idle persistent HTTP/2 connections to the node renderer are kept alive, preventing SSR failures from stale connections. [PR 3069](https://github.com/shakacode/react_on_rails/pull/3069) by [justin808](https://github.com/justin808).
 
 #### Improved
 
 - **Doctor enforces strict version constraints**: `react_on_rails:doctor` now escalates non-exact gem and npm version specs (`^`, `~`, `>=`) from warnings to errors, matching the runtime VersionChecker behavior. Wildcard checks now also cover Pro packages (`react-on-rails-pro`, `react_on_rails_pro`). [PR 3070](https://github.com/shakacode/react_on_rails/pull/3070) by [justin808](https://github.com/justin808).
 - **Error messages recommend doctor**: Runtime version-check crashes, configuration validation errors, and autobundling errors now suggest running `bundle exec rake react_on_rails:doctor` for diagnostics and `bundle exec rake react_on_rails:sync_versions WRITE=true` to fix version mismatches. [PR 3070](https://github.com/shakacode/react_on_rails/pull/3070) by [justin808](https://github.com/justin808).
 - **`sync_versions` handles range specs**: Version ranges like `^16.5.0`, `~16.5.0`, and `>=16.5.0` are now parsed and rewritten to the exact expected version instead of being skipped as unsupported. When `FIX=true` is set, doctor auto-runs `sync_versions` to fix detected mismatches. [PR 3070](https://github.com/shakacode/react_on_rails/pull/3070) by [justin808](https://github.com/justin808).
+- **[Pro] Improved node renderer error messages for malformed render requests**: Added early validation for missing or invalid `renderingRequest` payloads on the render endpoint, returning actionable 400 messages that include received type, body keys, and likely causes (truncation, malformed multipart, content-length mismatch). [PR 3068](https://github.com/shakacode/react_on_rails/pull/3068) by [justin808](https://github.com/justin808).
 
 #### Fixed
 
 - **[Pro]** **Fixed TanStack Router SSR hydration mismatches in the async path**: Client hydration now restores server match data before first render, uses `RouterProvider` directly to match the server-rendered tree, and stops the post-hydration load when a custom `router.options.hydrate` callback fails instead of continuing with partially hydrated client state. [PR 2932](https://github.com/shakacode/react_on_rails/pull/2932) by [justin808](https://github.com/justin808).
 - **[Pro] Fixed infinite fork loop when node renderer worker fails to bind port**: When a worker failed during `app.listen()` (e.g., `EADDRINUSE`), the master previously reforked unconditionally, causing an infinite fork/crash loop that consumed CPU and filled logs. Workers now send a `WORKER_STARTUP_FAILURE` IPC message to the master before exiting; the master sets an abort flag and exits with a clear error message instead of reforking. Scheduled restarts and runtime crashes continue to refork as before. [PR 2881](https://github.com/shakacode/react_on_rails/pull/2881) by [justin808](https://github.com/justin808).
+- **[Pro] Fixed Pro generator multiline and template-literal rewrites**: The Pro install generator now correctly handles multiline non-parenthesized `gem "react_on_rails"` declarations while preserving trailing options, and correctly rewrites module specifiers around template literals by preserving escaped sequences and detecting multiline template-literal starts after a closed inline template. [PR 2918](https://github.com/shakacode/react_on_rails/pull/2918) by [justin808](https://github.com/justin808).
+- **[Pro] Fixed SSR failures from stale persistent HTTP/2 connections to the node renderer**: When idle connections became stale (closed by the node renderer but still considered active by the Ruby side), render requests could be truncated mid-flight, producing confusing `FST_ERR_CTP_INVALID_CONTENT_LENGTH` and "INVALID NIL or NULL result for rendering" errors. The new `renderer_http_keep_alive_timeout` config (default: 30s) prevents this by closing idle connections before they go stale. Content-Length mismatches now produce specific diagnostic messages instead of generic errors, and sensitive field names are filtered from diagnostic output. Fixes [Issue 3071](https://github.com/shakacode/react_on_rails/issues/3071). [PR 3069](https://github.com/shakacode/react_on_rails/pull/3069) by [justin808](https://github.com/justin808).
