     * Changes in between these calls (as long as the file is open) are buffered by the server, so iteratively calling
     * this method should provide all changes (size of that buffer can be adjusted through
     * {@link jcifs.Configuration#getNotifyBufferSize()}).
     * If the server cannot fulfill the request because the changes did not fit the buffer
     * it will return an empty list of changes.

* Cases for other API changes require TOC approval
    * Simple `meshConfig` changes have been approved in the past. Functionality should not be enabled by default.
* For large API changes, 2 members of the TOC must approve the PR before release manager approval in the release branch
  of the istio/api repository. This does not have to wait for the weekly TOC meeting.
