 ### Running Migrations
 
 As soon as `storage.defineItem` is called, WXT checks if migrations need to be ran, and if so, runs them. Calls to get or update the storage item's value or metadata (`getValue`, `setValue`, `removeValue`, `getMeta`, etc) will automatically wait for the migration process to finish before actually reading or writing values.
-
-### Default Values
-
-With `storage.defineItem`, there are multiple ways of defining default values:
-
-1. `fallback` - Return this value from `getValue` instead of `null` if the value is missing.
-
-   This option is great for providing default values for settings:
-
-   ```ts
-   const theme = storage.defineItem('local:theme', {
-     fallback: 'dark',
-   });
-   const allowEditing = storage.defineItem('local:allow-editing', {
-     fallback: true,
-   });
-   ```
-
-2. `init` - Initialize and save a value in storage if it is not already saved.
-
-   This is great for values that need to be initialized or set once:
-
-   ```ts
-   const userId = storage.defineItem('local:user-id', {
-     init: () => globalThis.crypto.randomUUID(),
-   });
-   const installDate = storage.defineItem('local:install-date', {
-     init: () => new Date().getTime(),
-   });
-   ```
-
-   The value is initialized in storage immediately.

-# Entrypoint Loaders
-
-Because entrypoint options, like content script `matches`, are listed in the entrypoint's JS file, WXT has to import them during the build process to use those options when generating the manifest.
-
-There are two options for loading your entrypoints:
-
-1. `vite-node` - default as of `v0.19.0`
-2. `jiti` (**DEPRECATED, will be removed in `v0.20.0`**) - Default before `v0.19.0`
-
-## vite-node
-
-Since 0.19.0, WXT uses `vite-node`, the same tool that powers Vitest and Nuxt, to import your entrypoint files.
-
-If you use any runtime packages that depend on `webextension-polyfill`, you need to add them to [Vite's `ssr.noExternal` option](https://vitejs.dev/config/ssr-options#ssr-noexternal):
-
-```ts
-export default defineConfig({
-  vite: () => ({
-    ssr: {
-      noExternal: ['@webext-core/messaging', '@webext-core/proxy-service'],
-    },
-  }),
-});
-```
-
-:::details Why?
-This tells Vite it needs process these module's, letting WXT properly disable the polyfill in the NodeJS environment so it doesn't cause any build errors like this:
-
-```
-ERROR This script should only be loaded in a browser extension
-```
-
-:::
-
-To get a list of installed packages that use on `webextension-polyfill`, run your package manager's `list` command. Here's an example with PNPM:
-
-```sh
-$ pnpm why webextension-polyfill
-
-dependencies:
-@webext-core/messaging 1.4.0
-└── webextension-polyfill 0.10.0
-@webext-core/proxy-service 1.2.0
-├─┬ @webext-core/messaging 1.4.0 peer
-│ └── webextension-polyfill 0.10.0
-└── webextension-polyfill 0.12.0 peer
-
-devDependencies:
-@wxt-dev/module-vue 1.0.0
-└─┬ wxt 0.19.0-alpha1 peer

-webextension-polyfill 0.12.0
-wxt 0.19.0-alpha1
-└── webextension-polyfill 0.12.0
-```
-
-Ignoring WXT itself (it's added automatically for you), there are three packages that depend on the polyfill: `@wxt-dev/module-vue`, `@webext-core/messaging`, and `@webext-core/proxy-service`. Since the vue module is a build dependency, with no runtime code, you don't have to add it. That means for this case, you need to add `@webext-core/messaging`, and `@webext-core/proxy-service`, as shown in the original code snippet.

-
-### `vite-node` Entrypoint Loader
-

-
-<!-- prettier-ignore -->
-```ts

-Importing variables and using them in the entrypoint options:

-```ts
-// entrypoints/content.ts
-import { GOOGLE_MATCHES } from '~/utils/constants'
-
-export default defineContentScript({
-  matches: [GOOGLE_MATCHES],
-  main: () => ...,
-})
-```
-
-Using Vite-specific APIs like `import.meta.glob` to define entrypoint options:
-
-```ts
-// entrypoints/content.ts
-const providers: Record<string, any> = import.meta.glob('../providers/*', {
-  eager: true,
-});
-
-export default defineContentScript({

-    (provider) => provider.default.paths,
-  ),
-  async main() {
-    console.log('Hello content.');
-  },
-});

-
-Basically, you can now import and do things outside the `main` function of the entrypoint - you could not do that before. Still though, be careful. It is recommended to avoid running code outside the `main` function to keep your builds fast.

-### Drop CJS Support
-
-WXT no longer ships with Common JS support. If you're using CJS, here's your migration steps:
-
-1. Add [`"type": "module"`](https://nodejs.org/api/packages.html#type) to your `package.json`.
-2. Change the file extension of any `.js` files that use CJS syntax to `.cjs`, or update them to use EMS syntax.
-
-Vite also provides steps for migrating to ESM. Check them out for more details: https://vitejs.dev/guide/migration#deprecate-cjs-node-api

-## v0.17.0 &rarr; v0.18.0
-
-### Automatic MV3 `host_permissions` to MV2 `permissions`
-
-> Out of an abundance of caution, this change has been marked as a breaking change because permission generation is different.
-
-If you list `host_permissions` in your `wxt.config.ts`'s manifest and have released your extension, double check that your `permissions` and `host_permissions` have not changed for all browsers you target in your `.output/*/manifest.json` files. Permission changes can cause the extension to be disabled on update, and can cause a drop in users, so be sure to double check for differences compared to the previous manifest version.
-
-## v0.16.0 &rarr; v0.17.0
-
-### Storage - `defineItem` Requires `defaultValue` Option
-
-If you were using `defineItem` with versioning and no default value, you will need to add `defaultValue: null` to the options and update the first type parameter:
-
-```ts
-const item = storage.defineItem<number>("local:count", { // [!code --]
-const item = storage.defineItem<number | null>("local:count", { // [!code ++]
-defaultValue: null, // [!code ++]
-  version: ...,
-  migrations: ...,
-})
-```
-
-The `defaultValue` property is now required if passing in the second options argument.
-
-If you exclude the second options argument, it will default to being nullable, as before.
-
-```ts
-const item: WxtStorageItem<number | null> =
-  storage.defineItem<number>('local:count');
-const value: number | null = await item.getValue();
-```
-
-### Storage - Fix Types In `watch` Callback
-
-> If you don't use TypeScript, this isn't a breaking change, this is just a type change.
-
-```ts
-const item = storage.defineItem<number>('local:count', { defaultValue: 0 });
-item.watch((newValue: number | null, oldValue: number | null) => { // [!code --]
-item.watch((newValue: number, oldValue: number) => { // [!code ++]
-  // ...
-});

-### Renamed `zip.ignoredSources` to `zip.excludeSources`
-
-```ts
-// wxt.config.ts
-export default defineConfig({
-  zip: {
-    ignoredSources: [
-      /*...*/
-    ], // [!code --]
-    excludeSources: [
-      /*...*/
-    ], // [!code ++]
-  },
-});
-```
-
-### Renamed Undocumented Constants
-
-Renamed undocumented constants for detecting the build config at runtime in [#380](https://github.com/wxt-dev/wxt/pull/380). Now documented here: https://wxt.dev/guide/multiple-browsers.html#runtime
-
-- `__BROWSER__` → `import.meta.env.BROWSER`
-- `__COMMAND__` → `import.meta.env.COMMAND`
-- `__MANIFEST_VERSION__` → `import.meta.env.MANIFEST_VERSION`
-- `__IS_CHROME__` → `import.meta.env.CHROME`
-- `__IS_FIREFOX__` → `import.meta.env.FIREFOX`
-- `__IS_SAFARI__` → `import.meta.env.SAFARI`
-- `__IS_EDGE__` → `import.meta.env.EDGE`
-- `__IS_OPERA__` → `import.meta.env.OPERA`
-
-## v0.13.0 &rarr; v0.14.0
-
-### Content Script UI API changes
-
-`createContentScriptUi` and `createContentScriptIframe`, and some of their options, have been renamed:
-
-- `createContentScriptUi({ ... })` &rarr; `createShadowRootUi({ ... })`
-- `createContentScriptIframe({ ... })` &rarr; `createIframeUi({ ... })`
-- `type: "inline" | "overlay" | "modal"` has been changed to `position: "inline" | "overlay" | "modal"`
-- `onRemove` is now called **_before_** the UI is removed from the DOM, previously it was called after the UI was removed
-- `mount` option has been renamed to `onMount`, to better match the related option, `onRemove`.
-
-## v0.12.0 &rarr; v0.13.0
-
-### New `wxt/storage` APIs
-
-`wxt/storage` no longer relies on [`unstorage`](https://www.npmjs.com/package/unstorage). Some `unstorage` APIs, like `prefixStorage`, have been removed, while others, like `snapshot`, are methods on the new `storage` object. Most of the standard usage remains the same. See https://wxt.dev/guide/storage and https://wxt.dev/api/reference/wxt/storage/ for more details ([#300](https://github.com/wxt-dev/wxt/pull/300))
-
-## v0.11.0 &rarr; v0.12.0
-
-### API Exports Changed
-
-`defineContentScript` and `defineBackground` are now exported from `wxt/sandbox` instead of `wxt/client`. ([#284](https://github.com/wxt-dev/wxt/pull/284))
-
-- If you use auto-imports, no changes are required.
-- If you have disabled auto-imports, you'll need to manually update your import statements:
-  ```ts
-  import { defineBackground, defineContentScript } from 'wxt/client'; // [!code --]
-  import { defineBackground, defineContentScript } from 'wxt/sandbox'; // [!code ++]
-  ```
-
-## v0.10.0 &rarr; v0.11.0
-
-### Vite 5
-
-You will need to update any other Vite plugins to a version that supports Vite 5.
-
-## v0.9.0 &rarr; v0.10.0
-
-### Extension Icon Discovery
-
-WXT no longer discovers icons other than `.png` files. If you previously used `.jpg`, `.jpeg`, `.bmp`, or `.svg`, you'll need to convert your icons to `.png` files or manually add them to the manifest inside your `wxt.config.ts` file.
-
-## v0.8.0 &rarr; v0.9.0
-
-### Removed `WebWorker` Types by Default
-
-Removed [`"WebWorker"` types](https://www.typescriptlang.org/tsconfig/lib.html) from `.wxt/tsconfig.json`. These types are useful for MV3 projects using a service worker.
-
-To add them back to your project, add the following to your project's TSConfig:
-
-```json
-{
-  "extends": "./.wxt/tsconfig.json",
-  "compilerOptions": {
-    // [!code ++]
-    "lib": ["ESNext", "DOM", "WebWorker"] // [!code ++]
-  } // [!code ++]
-}
-```
-
-## v0.7.0 &rarr; v0.8.0
-
-### `defineUnlistedScript`
-
-Unlisted scripts must now `export default defineUnlistedScript(...)`.
-
-### `BackgroundDefinition` Type
-
-Rename `BackgroundScriptDefintition` to `BackgroundDefinition`.
-
-## v0.6.0 &rarr; v0.7.0
-
-### Content Script CSS Output Location Changed
-
-Content script CSS used to be output to `assets/<name>.css`, but is now `content-scripts/<name>.css` to match the docs.
-
-## v0.5.0 &rarr; v0.6.0
-
-### Require a Function for `vite` Config
-
-The `vite` config option must now be a function. If you were using an object before, change it from `vite: { ... }` to `vite: () => ({ ... })`.
-
-## v0.4.0 &rarr; v0.5.0
-
-### Revert Move Public Directory
-
-Change default `publicDir` to from `<rootDir>/public` to `<srcDir>/public`.
-
-## v0.3.0 &rarr; v0.4.0
-
-### Update Default Path Aliases
-
-Use relative path aliases inside `.wxt/tsconfig.json`.
-
-## v0.2.0 &rarr; v0.3.0
-
-### Move Public Directory
-
-Change default `publicDir` to from `<srcDir>/public` to `<rootDir>/public`.
-
-### Improve Type Safety
-
-Add type safety to `browser.runtime.getURL`.
-
-## v0.1.0 &rarr; v0.2.0
-
-### Rename `defineBackground`
-
-Rename `defineBackgroundScript` to `defineBackground`.

-# WXT Auto Icons
-
-## Features
-
-- Generate extension icons with the correct sizes
-- Make the icon greyscale during development
-
-## Usage
-
-Install the package:
-
-```sh
-npm i --save-dev @wxt-dev/auto-icons
-pnpm i -D @wxt-dev/auto-icons
-yarn add --dev @wxt-dev/auto-icons
-bun i -D @wxt-dev/auto-icons
-```
-
-Add the module to `wxt.config.ts`:
-
-```ts
-export default defineConfig({
-  modules: ['@wxt-dev/auto-icons'],
-});
-```
-
-And finally, save the base icon to `<srcDir>/assets/icon.png`.
-
-## Configuration
-
-The module can be configured via the `autoIcons` config:
-
-```ts
-export default defineConfig({
-  modules: ['@wxt-dev/auto-icons'],
-  autoIcons: {
-    // ...
-  },
-});
-```

Permission changes can cause the extension to be disabled on update, and can cause a drop in users, so be sure to double check for differences compared to the previous manifest version.

 - **storage:** Update docs ([91fc41c](https://github.com/wxt-dev/wxt/commit/91fc41c))
 
+#### ⚠️ Breaking Changes
+
+`v0.17.0` introduces several breaking changes to `wxt/storage`.
+
+First, if you were using `defineItem` with versioning and no default value, you will need to add `defaultValue: null` to the options and update the first type parameter:
+
+```ts
+// < 0.17
+const item = storage.defineItem<number>("local:count", {
+  version: ...,
+  migrations: ...,
+})
+
+// >= 0.17
+const item = storage.defineItem<number | null>("local:count", {
+  defaultValue: null,
+  version: ...,
+  migrations: ...,
+})
+```
+
+The `defaultValue` property is now required if passing in the second options argument.
+
+If you exclude the second options argument, it will default to being nullable, as before.
+
+```ts
+const item: WxtStorageItem<number | null> =
+  storage.defineItem<number>('local:count');
+const value: number | null = await item.getValue();
+```
+
+> If you don't use typescript, there aren't any breaking changes, this is just a type change.
+
+For storage items that are not nullable, the `watch` callback types has improved and will use the default value instead of `null` when the value is missing:
+
+```ts
+// >=0.17
+const item = storage.defineItem<number>('local:count', { defaultValue: 0 });
+item.watch((newValue: number | null, oldValue: number | null) => {
+  // ...
+});
+
+// >=0.17
+const item = storage.defineItem<number>('local:count', { defaultValue: 0 });
+item.watch((newValue: number, oldValue: number) => {
+  // ...
+});
+```
+
+You can also access the default value directly off the item:
+
+```ts
+console.log(item.defaultValue); // 0
+```
+
+The second breaking change is that migrations for versioned items only run when the extension is updated. Before, they were ran whenever the storage item was created, in any entrypoint (background, popup, content script, etc). Now, in v0.17, storage items will only run migrations when the `browser.runtime.onInstalled` event is fired with `reason = "update"` in the background. See the updated docs to make sure they run correctly: https://wxt.dev/guide/storage.html#running-migrations. TLDR: you need to import all storage items into the background entrypoint for the `onInstalled` hook to fire properly and thus run the migrations.
+
+To keep the old behavior, call the new `migrate` function to run migrations as soon as an item is defined:
+
+```ts
+const item = storage.defineItem(...);
+item.migrate();
+```

+#### ⚠️ Breaking Changes
+
+In [#398](https://github.com/wxt-dev/wxt/pull/398), HTML pages' JS entrypoints in the output directory have been moved. Unless you're doing some kind of post-build work referencing files, you don't have to make any changes.
+
+- Before:
+  ```
+  .output/
+    <target>/
+      chunks/
+        some-shared-chunk-<hash>.js
+        popup-<hash>.js
+      popup.html
+  ```
+- After:
+  ```
+  .output/
+    <target>/
+      chunks/
+        some-shared-chunk-<hash>.js
+      popup.html
+      popup.js
+  ```
+
+This effects all HTML files, not just the Popup. The hash has been removed, and it's been moved to the root of the build target folder, not inside the `chunks/` directory. Moving files like this has not historically increased review times or triggered in-depth reviews when submitting updates to the stores.

+- `wxt/storage` no longer relies on [`unstorage`](https://www.npmjs.com/package/unstorage). Some `unstorage` APIs, like `prefixStorage`, have been removed, while others, like `snapshot`, are methods on the new `storage` object. Most of the standard usage remains the same. See https://wxt.dev/guide/storage and https://wxt.dev/api/reference/wxt/storage/ for more details ([#300](https://github.com/wxt-dev/wxt/pull/300))
