リリースサイクル

As the users of Hadoop ask for more stability and fewer release
upgrades to deal with, I think we should move the release cycle out
to 3 months from the current 2. I propose that we move the feature-
freeze date for 0.16 to the first week of January and 0.17 to first
week of April.

とんでもない速さで，マイナーバージョンをあげていくんですね．でも，ひとまず，3ヶ月に1回になるようで．ありがたい話です．
