## How are these products versioned?

* **Appkit** is versioned according to updates to the code base.
* **App Studio Enterprise** versions are loosely tied to the version of the Appkit framework it includes. An update from **4.8.0** to **4.9.0** may not include any changes to App Studio Enterprise.

## What about compatibility?

* Any version of **Appkit** can be used with Fusion 4.x. However, only Appkit 4.6.0+ can be used with Fusion 5.y.
* **App Studio Enterprise** can be used with any version of Fusion or Appkit.

## Can these products be updated independently?

* **Appkit** can be **Upgrade Appkit in Existing Apps** independently, assuming there are no version [compatibility](#what-about-compatibility) issues.
* **App Studio Enterprise** is released when a new version of Appkit is released. As a result, App Studio Enterprise itself does not need to be updated. To move to the latest code base, simply update the Appkit version within the project.

<Accordion title="Upgrade Appkit in Existing Apps">
  When you create an Appkit webapp, it uses a specific version of Appkit. Appkit releases occur independently of App Studio releases.

  You can upgrade web apps to use the latest version of Appkit.

  **How to upgrade**

  1. Stop the app.
  2. In the `package.json` file at the root of your project, update the `appkit-ui` dependency to the latest Appkit version, for example:

     ```json theme={"dark"}
     "appkit-ui": "http://appkit.lucidworks.com/repo/4.2.0/appkit-ui.tar.gz",
     ```
  3. In the `pom.xml` file at the root of your project, update the value of the `parent.version` property to the latest Appkit version, for example:

     ```xml theme={"dark"}
         <parent>
             <groupId>twigkit</groupId>
             <artifactId>twigkit.app.js</artifactId>
             <version>4.2.0</version>
         </parent>
     ```
  4. Upgrade the Appkit Social module, if required.
  5. Perform any additional upgrade steps that are required for a specific Appkit upgrade. See the [Appkit Release Notes](/docs/4/app-studio/release-notes/appkit/overview) for more information.
  6. Start the app.
