<p>
Deletes one or more versions of a launch template.
</p>
<p>
You can't delete the default version of a launch template; you must first assign a different version as the
default. If the default version is the only version for the launch template, you must delete the entire launch
template using <a>DeleteLaunchTemplate</a>.
</p>
<p>
You can delete up to 200 launch template versions in a single request. To delete more than 200 versions in a
single request, use <a>DeleteLaunchTemplate</a>, which deletes the launch template and all of its versions.
