i've categorized up through 1.10 now. whoooaaaah, we're 1/4th way theeeeeere whooooaaaaaaaoh!

Something that might help, or might make things more complicated: I've been thinking about grouping changes into three user profiles: "compiler dev", "library dev", and "application dev". Lang changes primarily effect the first two groups IMO, but can trickle down.

Yeah, and while compiler features may not have changed, trends over time in "libs" or even "apps" can change how people perceive Rust. Think of all the error handling libraries - not much changed (other than the Error trait?), but "idiomatic" or "blog post idiomatic" might have.

I'd probably agree with you - "Rust as a language" probably has changed less than most people think over time. But "Rust as an ecosystem" has probably changed more, though likely less than is perceived. But even looking at async, there has been a lot of change:

e.g. Tokio 0.1, 0.2, 0.3, or async-std, or even just futures-rs. Without passing judgement, the "style" of all four of these permutations are significantly different, and all contribute to perceptions of "churn". Other ecosystems likely have similar stories.
