To ensure games run well on Linux either via Native Linux builds or Windows games with Proton, part of the magic is in the Steam Linux Runtime. A new version of it, the Steam Linux Runtime 4.0 was recently put up with some pretty big changes.

What's the point of it? It ensures Steam and games run through Steam on Linux work properly across all the many different Linux distributions. Another secret Valve sauce for Linux. Well, not secret at all but you get my meaning I'm sure.

That's a good sign, that Valve is moving at least the runtimes to 64bit only. Maybe that means the client is under similar scrutiny internally. Recently when Fedora was discussing dropping more 32bit libraries Steam came up as a big issue.

Didn't they already announce they're going to drop 32 bit?

For windows at least, but I assume they'd do it across the board at once
