Q. Attachment eTags are showing up prefixed with "W/"
A. This is expected depending on the CDN/webserver configuration. This add-on implements a workaround to support this.

Cloudflare has been seen to prepend W/ to some eTags to transform them from a strong eTag to a weak eTag.

Q.Attachment Etags are no longer a quoted number like standard XenForo eTags
A. Make sure the internal_data path has (depending on exact nginx configuration):
  add_header Etag $upstream_http_etag;
