What a fantastic list!
I always find if very cumbersome to figure out in what Rust version features are stabilized. You’ll usually end up on their respective GitHub issue pages, but it usually doesn’t clearly state what version it got stabilized for. Does the author have any tips regarding this?
Not exactly what you’re asking for but there is The Unstable Book which lists all the features along with their tracking issue. Beyond that I tend to rely on the This Week in Rust posts or Rust podcasts that tend to list the standout features.
