Valve has shipped an updated Steam Deck Client to the Stable channel, bringing some improvements that were previously available in the Beta and Preview channels. The biggest update is the local network game transfers, which allow users to copy their Steam game installation and update files from one PC to another over a local network.

The new Steam Deck Client update also adds several other general features and Steam input support, including advanced HDR options in Developer Settings, added support for Sony DualSense Edge controller, Xbox Series X controllers connected via the Xbox Wireless Adapter, Logitech F310 controller, and more, as well as improves some features and fixes for various bugs.Here are the full release notes:

Local Network Game Transfers

• Added new feature that allows Steam users to copy existing Steam game installation and update files from one PC to another over a local area network, without having to download and install from a Steam content server on the internet. This helps you stay below your ISP monthly transfer limits and can speed up installs or updates.
• Steam users have control over who files can be sent to: self only, friends only, or everyone. The default setting is self only.
