This version is not compatible with all previously released ASUS firmware and uncertified third party firmware. <-- God damn it, I missed that part!
Must be annoying for Merlin that ASUS shipped new firmware just two days after latest Merlin version went out.
It is, however, good to see that 2-3 year old routers like my RT-AC68U are still actively & officially supported by manufacturer with both security fixes, new features, and generally better user interfaces influenced by Merlin.
Merlin 380.59.0 still seems to avoid the 2.4GHz challenges it had on .57 and .58
My LG-TV stays connected and more reliable than ever.
No other change in surroundings.
