Valve have again released another update to the Steam Library beta. There's still a lot of issues with it but they seem to be getting through the major problems.
For the new Library they've added a screenshots section to pages for non-Steam games, non-Steam games should be available when Family View is enabled and they fixed an issue with the play bar going over the links bar on the game details when library sharing is active.
Something I saw a few users talk about is how Remote Play was broken in a number of places. Some of that should now be fixed! In the release notes they said a bug causing some games, including shortcuts, to be unavailable for streaming was fixed.
As for SteamVR, they made the desktop overlay to switch from the physical mouse back to laser mouse (from the HMD or control) on a click instead of a timeout.
Finally, just for Linux users, Valve say they've fixed an issue with titles that depended on SDL_image not working on distributions that use SDL2 2.0.10.
