In addition to the [version](/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/version) field, which is used for update purposes, [version_name](https://developer.chrome.com/docs/extensions/mv3/manifest/version/) can be set to a descriptive version string and will be used for display purposes if present.

If no **version_name** is present, the **version** field will be used for display purposes as well.
