On a general note I think that "stability" when it comes to widely used critical bits of sw is a good idea. For example the JFS has got very few updates over the past (in part because IBM stopped sponsoring its development many years ago) and it is still very reliable and well behaved. In some other projects instead there are many updates that may not always be necessary, perhaps because if someone's job title is "maintainer of X" it is difficult to hold back from doing updates.
