+## All packages
+
+- Requires TypeScript v5 or greater.
+- Dropped Node.js v14 support. Now requires v16.20 and above.
+- Updated many dependencies to their latest major version.
+
+### Migrated to ECMAScript modules (`.mjs`)
+
+TODO
+
+## @boost/common
+
+- Migrated from `resolve` to `enhanced-resolve` for `PathResolver`. This is to support
+  `package.json` exports. We currently support the `import`, `require`, and `node` conditions.
+
 ## @boost/plugin
+
+- Updated the `Loader` to use dynamic `import()` for loading modules, instead of our `requireModule`
+  function from `@boost/module`. This is to support both CJS and ESM files.
+
+## @boost/test-utils
+
+- Migrated from Jest to Vitest.
+- Removed the `copyFixtureToMock` function.
