Official USA change-log:
- Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience
A few u32s in .text were updated which are version-related. Minus SDK version-values used with ErrDisp, this just changed the fpdver value sent for HTTPS request(s) from 3 to 4(this is also used with the user-agent).
The only change here(even including the NCCH header) was that the contents of RomFS:/dummy.txt was changed from 1-byte '1' to '2'.
This just updated the RomFS:/CACERT_PUBLIC_CA_6.der file. This replaced the "VeriSign" cert with "CyberTrust ..."
System update report(s):
Online multiplayer sysupdate message
Following the server maintenance on February 1, 2016, the nasc URL now returns an error indicating a sysupdate is required when a pre-v10.5 3DS tries to send a request with that URL. The server now checks that the fpdver value sent in the request is the newer one described in the above friends-module section.
Hence, this blocks "everything" requiring friends-login including online-multiplayer where the 3DS has friends-module <v10.5 installed. This somehow doesn't affect the YouTube application even though it does a friends-login.
