Maybe you have misunderstood hncxy, the last version means the last big change for the very bad source code base because too many rubbish code, then Actions will not do big change, and we will keep and try to follow the kernel.org version for 3.10.
The Guitar developer team are trying to clean the unnecessary code so that we can have a clean source code to update to the 3.10.93. They delayed is because we need wait the display structure to change to HDMI master and slave can be set by users. We and Actions do not want to get the bad impression like the source code before.
I do believe the guitar develop team will update the kernel to the 3.10.93, and then also update to xapple community as the upstream code base.
For me personal, as most guys are now developing Guitar and Hikey, I do look over the Banana.
Hope you understand.
