1) Ability to use "Rear Height" instead of "Surround Height" with Auro 3D (which then allows using FH+RH for all 3 formats: Atmos, DTS:X, Auro 3D using a single Audyssey calibration)
2) HDMI 2.0a(HDR)
3) Add the "DTS: X" and "DTS Neural:X" sound mode feature.
4) When the customer plays DD + stream that exceeds 504kbps at specific Media Player (Tmall Magic box TMB300A), the sound might not be output from the AV receiver. The symptom is a problem that the product has the failure in playing DD + stream that exceeds 504kbps. (Improvement request from Dolby Laboratories, Inc.)
5) Even if the customer sets "Tone Control" to "ON" with the WEB control setting screen of the AV receiver, and the numerical value of Bass or Treble is changed, the AV receiver doesn't reflect a set value. The symptom is a problem that the AV receiver cannot set Bass or Treble from the WEB control.
6) When the input source of AV receiver switches automatically from Blu-ray (function during SACD playback) to TV Audio, the sound of the broadcast via ARC from specific TV (Panasonic) might not be outputted. The symptom is a problem that the sound of the broadcast via ARC from specific TV (Panasonic) might not be outputted.
7) Even if the customer sets Level FR from the WEB control screen of the AV receiver, the customer cannot confirm a set value of Level FR because the display on the WEB control screen doesn't change. The display of Level FR on the WEB control screen doesn't change but Level FR on the AV receiver side is changed. The symptom is a problem that the customer cannot confirm a set value of Level FR because the display on the WEB control screen doesn't change.
8) When the customer connects MAC Book to the AV receiver and then the specific MP3 file (Album art size is bigger than 1000x1000 pixels) is played from iTunes via the AirPlay, the AV receiver reboots before starting the playback of the MP3 file. The symptom is a problem that the AV receiver reboots before starting the playback of the MP3 file.
9) If the customer inserted the iPod classic to USB-A terminal on AV Receiver with standby mode (over 8 hours or more), when the customer turns on the power of AV receiver, the AV receiver cannot connect to the iPod again. The symptom is a problem that the AV receiver cannot connect to the iPod when the customer turns on the power of AV receiver.
10) When the customer connects the AV receiver to HDMI output of specific Streaming Media Player (Roku 4) that the output setting of the resolution is set to 4K, the AV receiver doesn't output the video or the AV receiver has a latency until the output video. The symptom is a problem that the AV receiver doesn't output the video or the AV receiver has a latency until the output video.
11) Custom 2CH Playback added (AV7702MKII only)

This takes a total of 40 minutes or so, and you go through a series of screens, and the amp will turn off it's display, with only the porthole active, showing you the progress.

I would suggest using the LAN line for safety, as a choke whilst doing this can be deleterious to your amp.

Otherwise has been done in many countries for other models, and now, it's due for the 2015 Marantz models like the SR 7010, 6010 and AV 7702 MK II.

It has been suggested in some forums that one should avoid being in the Dolby Surround Mode when doing the upgrade.

Will see if the bugs reported are still present in this upgrade:

1: Upmixing of 2ch DTS content with Neural:X. - causes very audible distortion.
2: To use DSU on DTS and Neural:X on Dolby, set the player to output PCM

If you are a fan of Donnie Yen
Give 14 Blades a spin. 
It has amazing surround effects and with DTS X it's even better !
