Another new stable Steam-Client 16.03.2023 has been released for Linux.

16 March - Steam Client Update Released

A new Steam client has been released and will be automatically downloaded.

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 reduces internet traffic 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.
