Based on my understanding of the release process (still learning the
ropes, Ryan correct me if I'm wrong), we don't usually provide
pre-release installers until the 15th of a release month.
Looking back at the email I sent on the 7th, I can see how one could get
the impression that they'd be available earlier (keyword: "shortly").
If my understanding of the process is correct, I'll fix the email
template to make the timing clearer.
