So far, I can tell Wi-Fi has been dramatically improved.
Before the smallest interference would send the unit in 100% CPU mode and it would start stuttering and make strange noises until powered off. A few seconds with a microwave would suffice (100% of the time).
I just used my microwave for 4 minutes and the AA didn't drop a single packet. Major improvement as previously it was embarassingly bad. Next step would be to properly support 802.11 and getting rid of the limitation of a single mode of operation (Wi-Fi fully supports having simultaneous incoming and outgoing connections which would get rid of all the silly problems with hotspot mode and rid of the need for a "force hotspot mode" in the UI).
Multi-lingual support is a nice try for now. At least 30-40% is not adapted to selected language.
Of course, I mostly checked the French version... Quite a few things not exactly right...
