I did a little poking around around to see if I could find this, but unfortunately, I don't have full access to that information. If you want Samsung help, here's the Samsung Australia portal for support on that product: http://www.samsung.com/au/support/model/UA46D7000LMXXY
Give them an email or a call. They should be able to tell you what you need to know.

I have a Samsung UA46D7000.
When I purchased the TV I updated the firmware from the default 1018 to 1021, but could not find anywhere what the change is.
I see that there is a 1023 update for the firmware and wanted to know what the changes are.
