Love this new era of pointing ASI at a new firmware update to validate the manufacturer's claims.
GPT-6.1 happily reverse-engineered the scrambling and compression of several filesystems to hunt down exactly what changed.
Panasonic has released a new firmware update (version 1.85) for the UB9000, UB820, and UB420 4K Ultra HD Blu-ray players.
The official notes simply say: "Playability of Ultra HD Blu-ray Disc™." Panasonic doesn't provide any additional details, but updates like these are often aimed at improving disc compatibility, fixing playback freezes, reducing flickering issues, and addressing Dolby Vision or HDR-related bugs.
It's probably worth upgrading. New discs sometimes have playback issues because of newer and improved authoring techniques, and maybe even encoding improvements. But because we don't know what it does I'm just guessing here.
If you notice any improved playback on discs that were problems, please let us know.
***If you own a player without a front display, give it at least 15 minutes to update once you've downloaded the update, it actually takes quite some time.
