What I can't find anytime I download an update is any information on what it has actually changed. The download pages don't provide a link to any release notes. Even when you download a ZIP file to unzip to your USB drive, there's no information in there to tell you what's changed.
Just updated my TV to the latest firmware 1335.0 and I'm still not sure if this has added the promised eArc support yet.
On some forum threads people do discuss what has changed in various firmware updates but I have no idea where they are getting the info from. Any ideas?
