 # CHANGELOG
 
+## v3.0.0 (2025-06-18)
+
+### BREAKING CHANGES
+
+#### Switch to ES modules and named exports
+
+The `WebStorage` module is now exclusively available as an ES module (ESM), aligning with the modern JavaScript module standard. Additionally, it is no longer the default export — you must import it using a named import.
+
+**v2.x.x**
+```js
+import WebStorage from '@georapbox/web-storage';
+```
+
+**v3.x.x**
+```js
+import { WebStorage } from '@georapbox/web-storage';
+```
+
+#### API methods return [value, error] tuples
+
+All API methods now return `[value, error]` tuple-like values instead of accepting error callbacks. This allows developers to handle errors in a clean, synchronous style without using `try/catch` or providing callbacks. For example:
+
+**v2.x.x**
+```js
+const value = storage.getItem('key', value, (err) => {
+  console.error(err);
+});
+```
+
+**v3.x.x**
+```js
+const [value, error] = storage.getItem('key', value);
+
+if (error) {
+  console.error(error);
+}
+```
+
+#### Removed noop storage fallback
+
+In previous versions, if `localStorage` or `sessionStorage` was unavailable (e.g., due to privacy settings or Safari private mode), a silent in-memory fallback was used that mimicked the Storage API. This allowed methods like `setItem()` to return success even though no actual data was stored.
+
+This behavior has been removed to improve transparency and correctness. As of v3.0.0:
+
+- No fallback is used.
+- Errors are captured and returned via the `[_, error]` tuple-like value.
+- Developers can use `WebStorage.isAvailable()` for feature detection, or gracefully handle errors based on method output.
+
+This ensures failures are explicit and prevents false assumptions about persistence.
+
+### NEW FEATURES
+
+#### Type declarations for TypeScript
+
+Export type declaration files (`.d.ts`) for TypeScript users, ensuring better type safety and autocompletion support in TypeScript projects.
+
+### INTERNAL CHANGES
+
+- Update Node.js version requirement and dev dependencies to the latest versions.
+- Drop Jest in favor of @web/test-runner and Playwright for testing.
+- Drop rollup in favor of esbuild for bundling.
+
 ## v2.1.0 (2021-01-26)
 
 - Generate minified versions for ESM and CommonJS exported bubdles.

 - `WebStorage.isAvailable` static method, as of v2.x, accepts "localStorage" or "sessionStorage" strings as arguments.
 - On initialization the library **throws** if `driver` option is anything other than "localStorage" or "sessionStorage" and if `keyPrefix` option is not of type `String`.

 - Keep `devDependencies` up to date.
