 # shinyreact 0.1.0
 
-* Initial CRAN release.
+* Initial CRAN release. shinyreact is the server-side plumbing for the
+  `ui.tsx` pattern: the UI is a React client you own, and the Shiny server
+  contains only reactive computation. It ships no UI components.

-  `reactive_output()` sends JSON to `useShinyOutputValue()` hooks,
-  `send_message()` reaches `useShinyMessageHandler()`, and `page_react()` /
-  `page_react_html()` / `page_bare()` / `page_react_dep()` bootstrap the
-  client.
+* Dependencies of traditional Shiny outputs hosted inside a React tree are
+  discovered automatically and pushed to the client after each flush, so the
+  `ShinyOutput` component works with zero configuration.

+* `page_react()` serves `www/ui.js` (and `www/ui.css`, if present) as the
+  whole page, with no HTML file required. `page_react_html()` serves a
+  complete `index.html` that you own, `page_bare()` builds a page with no
+  Bootstrap, and `page_react_dep()` wraps an app's own bundle as an
+  `htmlDependency()` versioned by its mtime.
+
+* `reactive_output()` publishes any JSON-serializable value to the client's
+  `useShinyOutputValue()` hook, with no UI placeholder.
+
+* `send_message()` sends a custom message to the client's
+  `useShinyMessageHandler()` hook, namespaced to the current module.
 
 * `shinyreact.default` and `shinyreact.asis` input handlers give R and Python
-  the same view of the JSON a hook sends.
+  the same view of the JSON a `useShinyInput()` hook sends: records stay
+  lists, `[]` stays `list()`, and nested arrays keep their shape.
+
+* `wire_tap()` reads the websocket payloads a shinytest2 `AppDriver` recorded,
+  so tests can assert the exact inputs, outputs, and messages that crossed the
+  wire.
