What do you know of that existed in the past post-1.0 that doesn't exist today or has materially changed? I've been writing rust since about 1.4 back in 2015. I think once in ~2017 I ran into an issue where a bump in the compiler cause an existing crate to not build. That's it. It was bug that was quickly fixed. As style changes and new crates and features are build, old ones are still very stable/reliable and can be intermingled inside the same program. I have trouble thinking of a more stable ecosystem I've worked in.
