10 is the number that comes after 9, so I'd expect a 0.10. Rust has SemVer baked...

So I guess the version number is not intended to give any hint about how close Rust is to being frozen.

A package manager? Oh god.

Yup. rustpkg is a build tool that knows how to pull in dependencies and build them, too.

It is of course not mandatory, and won't really be used to distribute binary versions of Rust programs, just the source.
