You know patches are not released unless something needs correcting or a new feature has been added. It will be no secret when a patch is released all you have to do is look from time to time in the software section. Simply asking for patches is a waste of time it's up to you to keep an eye out for the latest patch and it seems to me you find it easier to ask than to look.
Keeping a receiver up to date is the owners responsibility so it's best you start checking on a regular basis.
