What about .NET 7? It's not mentioned in the referenced changelog, but .NET 7 went out of support 5 months ago back in May 2024 (7 is not an LTS version).

I see it was only just recently removed from the macOS image:
#10659

But it's still present in the Windows Server images:
https://github.com/actions/runner-images/blob/main/images/windows/toolsets/toolset-2022.json#L318
https://github.com/actions/runner-images/blob/main/images/windows/toolsets/toolset-2019.json#L411

If the .NET policy is the "2 latest LTS versions and 1 latest version" then I'd interpret that as .NET 6 and .NET 8 currently, as those are the two latest LTS versions (with 8 also being the 1 latest version).

Here's a PR removing it from the Windows images:
#10731
