Another important feature of this release, not mentioned in the notes: No major language changes. It's almost all tooling improvements, plus a few library functions getting stablized. This is great! It makes things more manageable for third-party implementations like mrustc and gcc-rust, for teaching resources that can spend time improving their docs on what's already there instead of documenting new stuff, and for the long-term health of the language itself. Here's for many more releases like this one!
