I don't even look at crate versions but the stuff works, very well. The resulting code is stable, robust and the crates save an inordinate amount of development time. It's like lego for high end, high performance code.

With Rust and the crates you can build actual, useful stuff very quickly. Hit a bug in a crate or have missing functionality? contribute.

Software is something that is almost always a work in progress and almost never perfect, and done. It's something you live with. Try any of this in C or C++.
