We've verified our player is compatible with this update, but there's also no need what so ever to update your players if you don't want to. All the updates are basically related to Desktop use.
Please note that this update is really consuming a lot of free space for the upgrade, so on Compute Sticks and similar devices there probably will not be enough free space. Again, another reason to ship your 32GB devices with a SD-card or USB memory stick with 16GB or preferably even 32GB if you can. Saves you a lot of trouble in the future!
