It's hard for a software project to make progress if the only way to reach users is non-rolling distros. To a large extent, the progress of software in non-rolling distros relies on enough other people using the intermediate versions from outside the distro repo, in rolling distros or on Mac/Windows.

That said, Ubuntu​ does carry (an obsolete version of) Rust: http://packages.ubuntu.com/search?keywords=rustc&searchon=na...

rustup.sh has been deprecated for months now.

It's in Debian now, so (as far as I know) that means it should end up in Ubuntu soonish.

Not everyone is on Linux.

FWIW, Debian unstable is stuck on rustc 1.14.0. You need experimental to, at the moment, get 1.15.1 (no 1.16 yet, but it's a tad early for that ; but in multiple occasions it took weeks to get new rustc releases into Debian).

Cargo in Debian, on the other hand, is stuck on 0.15.0... (current version for "stable rust" is 0.17.0) ; no newer version in experimental...

Yeah, Stretch just missed 1.15, it's a shame IMHO. They're fine with it though.

Now that we've gotten a lot of the kinks worked out, hopefully it won't be weeks in the future.

Personally I love this feature in a build tool. The Stack tool for Haskell does the same, which means I can use the newest version very easily, without depending on some volunteer's Ubuntu PPA (which may not exist).

No need to be hostile.
