They add release note on amp as well as manual update. Once you click, it will check if your firmware is up to date. Now, two features are slated at the end of this month. USB out and my favorite room correction. By the end of 2024, I think wiim amp will have extended feature that will make one of the most versatile amp out there. Room correction, addition peq band and add on feature high pass filter plus rca input to ability to use as out like what usb on firmware update slated this month. Once they got those features, it will be end game for me.
