If you mean official firmware updates by Samsung then yes, we have dozens of them.
If you mean official ROM porting then I guess no. There's little interest in this device to develop on daily basis, compared to, let's say Nexus 5. Most official port requires the developers to do nightly builds... This may be cumbersome for people with limited time such as pawitp, even though his skill is more than adequate to be an official device maintainer.
