 This change prevents Vite from swallowing and controlling OS-specific shortcuts, allowing better compatibility when combining the Vite dev server with other processes, and avoids the [previous caveats](https://github.com/vitejs/vite/pull/14342).
 
+### Remove `resolvePackageEntry` and `resolvePackageData` APIs
+
+The `resolvePackageEntry` and `resolvePackageData` APIs are removed as they exposed Vite's internals and blocked potential Vite 4.3 optimizations in the past. These APIs can be replaced with third-party packages, for example:
+
+- `resolvePackageEntry`: [`import.meta.resolve`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/import.meta/resolve) or the [`import-meta-resolve`](https://github.com/wooorm/import-meta-resolve) package.
+- `resolvePackageData`: Same as above, and crawl up the package directory to get the root `package.json`. Or use the community [`vitefu`](https://github.com/svitejs/vitefu) package.
+
+```js
+import { resolve } from 'import-meta-env'
+import { findDepPkgJsonPath } from 'vitefu'
+import fs from 'node:fs'
+
+const pkg = 'my-lib'
+const basedir = process.cwd()
+
+// `resolvePackageEntry`:
+const packageEntry = resolve(pkg, basedir)
+
+// `resolvePackageData`:
+const packageJsonPath = findDepPkgJsonPath(pkg, basedir)
+const packageJson = JSON.parse(fs.readFileSync(packageJsonPath, 'utf-8'))
+```
+
 ## Removed Deprecated APIs
 
 - Default exports of CSS files (e.g `import style from './foo.css'`): Use the `?inline` query instead
