crates.io should encourage use of latest stable version, not alpha/beta versions

[briansmith]

I just published ring 0.6.0-alpha so I could get some pre-release feedback. I expected that the page at https://crates.io/crates/ring would continue to say ring = "0.5.3" bit instead it says ring = "0.6.0-alpha". If somebody goes through the trouble to use the -alpha/-beta modifiers then they probably don't want the average user of their crate to use that version.

Agreed!

Especially given that you don't get a pre-release version without specifically selecting it; this seems quite consistent.
