No idea.
I’ll ask when Synology contacts me but it doesn’t make sense to attach to the CPU. It would make most sense to include in the DSM release notes where it belongs.

Digging deeper — “NK” is their new architecture.
The 5.x kernels were vastly different than their 4.x predecessors.
Synology J4125nk as the PLATFORM not the CPU
I’ll point this out to them when we chat.
In this case, it’s like how we separate
synology_dsm6, synology_dsm7, and synology_dsm72 package files for when we build the SPK.
