The absolute best way to stay on top of C# changes is the "What's New" docs: https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-13 https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/cs... Basically gives you a release-by-release highlight reel of what's changed and why it's changed. I glance at it every release cycle to get an idea of what's coming up. The even numbered releases are LTS releases while the odd numbered releases (like the forthcoming 9) are short term. But the language and runtime are fairly stable now after the .NET Framework -> .NET Core turbulence and now runtime upgrades are mostly just changing a value in a file to select your target language and runtime version.
