# Upgrade

Argyle periodically releases updates to its SDK's. These updates can include new functionalities, bug fixes, and security updates. For each new Link release, we recommend upgrading your SDK installation as soon as possible.

* To stay notified about new Link releases, subscribe to our [Changelog](https://changelog.argyle.com/). All Link SDK versions are also made available or will soon be made available on our public [Github repository](https://github.com/argyle-systems).
* For first time integrations, visit our [Initialization](/link/initialization) page.

## Web

Link for Web updates automatically with each release. You do not need to take any steps to upgrade your Web integration.

<Note>
  (Exception) If you are migrating from Link 4 to Link 5, note that the script plugin changed and is now:

  <script src="https://plugin.argyle.com/argyle.web.v5.js"></script>
  ```
