Time-based release trains have been shown to produce the best quality Free software. A time based release is one that does not wait for either features, or bug fixes - but is based (as purely as possible) on time. This enforces discipline in introducing fixes, gives predictability, and allows more regular releasing. It is also the case that we will necessarily release earlier, and then rapidly, incrementally bug fix releases based on the previous stable version. Thus if you have a need for the very highest quality version, it can make sense to defer a move until the first or perhaps second minor point release.
