Valve have put out their second beta update to the Steam client this year and this is actually a rather nice one.
Firstly, the big annoyance of Steam Play titles always having a zero-byte download when you first load the Steam client has been solved. It will still do it once but when you update them again now, it won't happen again (confirmed that myself). While in reality it was a really minor issue, it was damn annoying so it's great to see it fixed.
On top of that, Steam now supports ipv6 for "connections to download servers", DPI and screen size changes bugs were fixed, a new force quit option in the normal Steam Overlay if a game is frozen but the overlay still works that will be handy.
Steam Input gained support for the PDP Wired Fight Pad Pro and PDP Faceoff Wired Pro Controller along with some bug fixes.
Additionally, they added preliminary support for collecting source pipelines from Vulkan applications.
Then we get to the other Linux issues that were fixed, this time there's a pretty healthy dose on the menu:
- Fixed incorrect mouse wheel scrolling offsets
- Fixed an issue where some games wouldn't be properly detected as still running despite some of their processes still lingering in the background
- Fixed system tray including menu sometimes including too many recent game entries
- Fixed settings dialog incorrectly always prompting for a client restart
- Added gnutls 3 to the Steam Runtime, fixing network connectivity issues in many Steam Play titles
- Fixed an issue with host libssl on newer distributions breaking some titles
- Fixed a bug that could result in being unable to create shortcuts for certain games. To unblock previously affected titles, delete all *.ico and *.zip files from ~/.steam/root/steam/games and "Verify Game Files" to re-download the icons with the right format
- Fixed a crash with in-game purchases in Big Picture
