It's only changed if the <code>updateToLatestImageVersion</code> parameter for the compute environment is set to <code>true</code>. During an infrastructure update, if either <code>$Default</code> or <code>$Latest</code> is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment.
