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.
Didn’t they already announce they’re going to drop 32 bit?
Ah yes it looks like they did say that support for 32bit Windows is stopping soon:
Thanks I had missed this completely!
I assume this is the first step for them to move the client itself to being a 64bit executable later.
If you’re talking about Fedora, no. One of the maintainers just proposed it and the media/commenters in the community went crazy without knowing the facts.
For windows at least, but I assume they’d do it across the board at once
