 ### New features
-
+* `shiny run` now takes `reload-includes` and `reload-excludes` to allow you to define which files trigger a reload.
+* `shiny.run` now passes keyword arguments to `uvicorn.run`
 * The `@output` decorator is no longer required for rendering functions; `@render.xxx` decorators now register themselves automatically. You can still use `@output` explicitly if you need to set specific output options (#747).
 * Added support for integration with Quarto (#746).
 * Added `shiny.render.renderer_components` decorator to help create new output renderers (#621).

+
 #### API removals
 
 * `shiny.experimental.ui.FillingLayout` has been removed. (#481)
