release team! Thanks to all the release testers:

Yvan Roux, Neil Nelson, Hans Wennborg, Dimitry Andric, Albion Fung,

Also, a big thanks to everyone else who helped identify critical bugs,

And special thanks to Galina Kistanova and Andrei Lebedev for helping
to set up buildbots for the release branch!
