Comment FFS, that's not what a release candidate is (Score 2) 50
It's a release candidate, so it's meant for testing and preview purposes, like the developer preview of Android L.
If you label something as a release candidate, what you are saying is "we think this has been completely finished. Everybody check it out, and if we haven't screwed up, we'll rename it as the final version". Hence the name - it's a candidate for release. "Release candidate" is not another name for "preview" or "beta".
This is the kind of crap that gave KDE 4 such a bad reputation. Labelling things as done when they are still major works in progress. If you don't think it's finished, don't call it a release candidate. Don't label it as a new major version. If it's not finished, then it's neither of those things.
