Before being a Release, the build have to be a Beta so we can really test a "fix" build. If this "fix" build have no bug or w/e, then it can be a Release, what if you release the build without making a Beta test and someone find something critical ? Actually we can't really say that those builds from the buildbot are Beta, they are developper builds (even if they are compiled in release). After all, I'm just throwing an idea. Edit: + those builds from the buildbot aren't really official, there is no annouce to say "The build number X" is a Beta.
