From the article:

We have just released our fifth out-of-band update of Clang/C2 toolset. As always, this release has been driven by your feedback. While we’ve heard a lot of feature requests the one’s we’ve heard most frequently are that you want Clang 3.8 and you want x64-hosted compilers. We’re happy to say that we’re shipping both Clang 3.8 and x64-hosted compilers in the May 2016 release.
