+## [Unreleased]
+
+## [v4.0.0] - 2022-07-22
+### Added
+- Jest as default unit testing framework, with sample test suite for `main`.
+- Integrated Electron preload pattern.
+- NPM scripts:
+  - `watch-test` to run Jest in watch mode.
+  -  `next-rc`, `next-patch`, `next-minor` & `next-major` for quick
+    package version number advance.
+
+### Changed
+- Webpack will now take the module path alias from `tsconfig.json` and set it
+  for you thanks to `tsconfig-paths-webpack-plugin`. Manually set up in Webpack
+  config is no longer needed.
+- `tsconfig` now configured to use `ES2020` features, with module resolution
+  set to `Node16` to match the NodeJS version used by Electron.
+- Migrated to the new `createRoot` API introduced in React `v18`.
+- Some APIs changed in Electron `main` entry script:
+  - `mainWindow` now use `loadFile` API instead of `loadURL`.
+  - Replaced `app.on('ready')` with `app.whenReady()` to align with syntax from
+    [Electron official quick start guide](https://www.electronjs.org/docs/latest/tutorial/quick-start).
+- `electron-builder` now configured to build `universal` `dmg` for mac, 32 &
+  64 bit `exe` for Windows.
+- Moved `electron-builder`, Webpack & Webpack-related packages to
+  `optionalDependencies`.
+- Revamped `README`.
+- __*Starting from this version, the maintenance schedule will be on a monthly
+  update basis to keep the package dependencies up to date and keep the
+  development going.*__
+
+### Fixed
+- Allow to use `import default` statement on non ES modules (e.g. React,
+  lodash) by enabling `esModuleInterop` in `tsconfig`.
+  [#14](https://github.com/Devtography/electron-react-typescript-webpack-boilerplate/issues/14)
