+Starting with version `3.1.0`, you can also use the `multipleVersions` option to track dependencies in different version as a different dependency.
+It can be particularly useful in case a dependency changed its license between two versions.
+
+Note that this option is `false` by default (mainly to keep backward compatibility).
+
+```javascript
+license({
+  thirdParty: {
+    includePrivate: false,
+    multipleVersions: true,
+    output: {
+      file: path.join(__dirname, 'dist', 'dependencies.txt'), // Path of the license report
+      encoding: 'utf-8', // default is UTF-8
+      template(dependencies) {
+        return dependencies.map((dependency) => `${dependency.name}:${dependency.version} -- ${dependency.license}`).join('\n');
+      },
+    },
+  },
+})
+```
