 The `WizardFunctions`, `WizardActions`, and `GetWizardArgs` types have been removed from `@nuxt/devtools-kit`.

+## Vite DevTools Integration is Now Always Enabled
+
+The `viteDevTools` module option has been removed. Nuxt DevTools now always integrates with [Vite DevTools](https://github.com/vitejs/devtools) as a dock entry. The built-in floating panel has been removed — DevTools is accessed through the Vite DevTools panel instead.

+```diff
+export default defineNuxtConfig({
+  devtools: {
+    enabled: true,
+-   viteDevTools: true,
+  },
+})
+```
+
+### `client.devtools` Methods Now Control Vite DevTools
+
+The `client.devtools.open()`, `client.devtools.close()`, and `client.devtools.toggle()` methods still work but now control the Vite DevTools panel:
+
+- `open()` opens the Vite DevTools panel and switches to the Nuxt DevTools dock entry
+- `close()` closes the Vite DevTools panel
+- `toggle()` toggles the Nuxt DevTools dock entry in the Vite DevTools panel
+
+The `Shift+Alt+D` keyboard shortcut now toggles the Nuxt DevTools entry in the Vite DevTools panel.
+
+### `client.devtools.popup` Removed
+
+The Picture-in-Picture popup feature (`client.devtools.popup`) has been removed. This was an experimental feature that required Chrome 111+.
+
+### `showPanel` and `minimizePanelInactive` Settings Removed
+
+The `showPanel` and `minimizePanelInactive` UI settings have been removed from `NuxtDevToolsOptions` as the built-in floating panel no longer exists.
