The official release is not yet announced, neither on scala-lang.org nor on the scala-announce mailing list. Your move seems overly aggressive. Why would you publish them before the maintainers?

I haven't announced anything and I haven't submitted this link to HN. I just added a comment to let people know that I might read and try to answer questions if they have any.

This submission's title at least reads "release notes" and not "2.12 released" like the submission yesterday, when people found the artifacts on Maven.

Thanks for work you're doing. Hope someday these efforts will be taken by official scala website.
