Perhaps one relevant point here is that we have often released a new minor version pretty quickly. Once 2.2.0 is out, we'll start to get bug reports. 2.1.1 came out two and half months after 2.1.0, for example. So we can always move to 5.6.x along the way. Obviously, we would want to do some testing, but it would even be possible to release builds with both 5.5.x and 5.6.x. Richard
