 # Upgrade from `v2.3.0` to `v2.4.0`
 
 The v2.4.0 version introduces the Product Model importer. If you are using the webhook no changes are requested as it will be automatically enqueued on every update.
 If you are using the cronjob, you have to add the `--importer="ProductModel"` option to the command that imports every minute:
