It's pretty weird, I'd assume it was a mistaken tagging except that the commit [1] is very clear in its intent. I still don't think they'd suddenly have decided to rush through it all and release 1.0 like this, so I'm still assuming there's a mistake or misunderstanding here.
The annual juliacon is happening right now. So yes the last few weeks of this release process have been very rushed. Only around 160 packages have made releases that pass their tests using Julia 1.0.0 at the moment, out of 1900ish total registered packages.
