Attention:
  When you update to version 1-302-008-518-128 and your gSpeaker Systemh is set to 5.2.4 up to 7.2.2 (number of 
  speakers are 7.1 to 9.2) and have set the gSpeaker Settingsh to use any of the following: Top middle, Top forward, 
  Top backward, Surround back, Front wide, or Front height, the Dolby Atmos stream will always be decoded. 
  
  When you update to version 1-295-008-518-126 and your gSpeaker Systemh is set to 5.2 (number of speakers are 2.0 to 
  5.2) the receiver will always decode Dolby TrueHD or Dolby Digital Plus instead of Dolby Atmos.  If you do not want this 
  change and the other improvements then update to or keep Version 1-290-008-518-121. After updating, you can't 
  revert back to the previous firmware version.

Version : 1-295-008-518-124

- Support Dolby Atmos ver.1.1
  This version will decode the appropriate Dolby TrueHD or Dolby Digital Plus instead of the Dolby Atmos stream when 
  the AVRfs speaker configuration is not configured to use Dolby Atmos enabled or ceiling speakers. This will produce the
  audio effect as it was intended based on Dolby's recommendation.

Other improvements:
- Reduces the time to output a video signal from the HDMI inputs when switching inputs.
- The GUI of the receiver does not always appear on the TV screen. This issue depends on the quality of HDMI cable.
- Sometimes the audio does not output when the receiver decodes the Dolby Atmos stream.
