Homebrew Installs 1.1?

So, I'd like to start exploring Rust, but when I install via homebrew, it only installs v1.1.0? Why is it behind by one minor version?

Homebrew only updates when someone puts in the work.

looks like they're still figuring out some things.

Thanks. As this was my first pass at installing Rust, I wanted to make sure I was doing this right. Some packages sometimes have better sources than the defaults.
