ATV 2.4 Update

I have had my ATV for several years now and have the 720p ATV black. Its been jailbroken and works perfectly on 2.4.
I can’t seem to get it to install a newer version.
What is the latest version?
The newer slick interface, looks great, i assume its on a newer version.

How can i get the new version, as in Maintenance it states i have the latest version?
Thank you

I believe that 2.4 is the latest version of aTV Flash (Black) available for the aTV. There have been hints that a newer version is in the works but no ETA given.
