Use of unstable library feature 'ord_max_min'

I cloned fresh and ran the command cargo build --release, but the console printed the following error messages:

My Rust version is rustc 1.20.0 (f3d6973f4 2017-08-27)

Thanks for reporthing this, this is breakage caused by rust-lang/rust#42496 :(. I'll prepare a fix.

This isn't it actually, see my comment below.

Actually no, never mind, sorry, I just realised this has been stable for a while. You should update your version of Rust if possible (using rustup update stable is using rustup). Let me know if that works out for you.
