The Stable Updates are the released versions. These have undergone testing are are deemed production worthy. The Development Updates contain the latest features and patches from the development team, but they have at most minimal testing. Unless you enjoy debugging other peoples code and wondering why something no longer works, stick to the Stable Updates.
