The following should be changed in the changelog.
Wrong: 1450.6 New function ? Menu ---> Display ----> Sound without a picture
Change to: This function has been implemented since 1422
Wrong: 1443.0 All 2015 JU and JS TV's(with quantum dots matrix) got updated to support HDR metadata and HDMI 2.0a. It was introduced in firmware 1443, so if you have that or later you've got HDR support.
Change to: -HDR support is also in 1422 (tested with ps4 HDR content and USB demo movies).
-In 1422 there is no symbol for HDR, maybe thats the update in 1443. (To check if HDR is activated, go to Menu->Display and look if brightness and contrast is automatically changed to 100%).
-In 1422 there is no support for Hybrid Log Gamma (HLG) -> This is the HDR standard in satilite television (you can test it with SES / Astra 4K+HDR demo channel), maybe there is support in 1433
