+Planned removal: GitLab <span class="removal-milestone">15.8</span> ()
+
+WARNING:
+This is a [breaking change](https://docs.gitlab.com/ee/development/deprecation_guidelines/).
+Review the details carefully before upgrading.
+
+The Live Preview feature of the Web IDE was intended to provide a client-side preview of static web applications, however complex configuration steps and a narrow set of supported project types limits its utility. With the introduction of the Web IDE Beta in GitLab 15.7, you can now connect to a full server-side runtime environment and with upcoming support for installing extensions in the Web IDE, we will support more advanced workflows than those available with Live Preview. As of GitLab 15.8, Live Preview will no longer be available in the Web IDE.
