Stable versions (i.e. minor version number even, e.g. 2.10.22) will only look for higher stable releases. But for unstable versions, we will want to look up the development releases too. So for instance GIMP 2.99.2 will warn if the development version 2.99.4 has been released, but also if the stable version 3.0.0 has been released (whatever is the highest, which is the stable version in this example).
