I am really happy to see this.
Partly because it is the first fully post-2.x release.
Partly because it is the first 3.xx release, breaking the '2 digit' 
minor version 'barrier' and mostly killing the spectre of an arbitrarily 
scheduled 4.0.

Even more, because it makes new features added since the 3.9 feature 
freeze late last May available to anyone.
It feels right to me that a bleeding-edge next-version preview release 
come out alone with the first production release of the new 'current' 
version.
