The next version of Steam Link for x86_64 Linux is now available.

You can get it from Flathub:

Make sure you follow the setup guide on that page before you install, if you have never used flatpak before.

Changes:

• Removed VDPAU support, instead preferring VA-API
  
• Fall back to software if hardware acceleration fails
  
• Fixed connecting after re-pairing with a computer
