SteamOS 3.7.10 Beta brings a Steam Deck OLED WiFi fix, new accessibility options and more work for other handhelds

Valve have released SteamOS 3.7.10 Beta bringing lots of fixes for the Steam Deck, additional accessibility options and a bit of work for more handhelds. This is available in the Beta and Preview channels via Settings > System > System Update Channel.
This update is part of a wider push for new accessibility options, which is also included in the Desktop Steam Big Picture mode. Nice to see Valve focusing on that not just for games, but for the Steam Client experience too.
On SteamOS you have this new accessibility menu and new options:
