Note: Note that 2.2-STABLE sometimes identifies itself as ``2.2.5-STABLE'' after the 2.2.5-RELEASE. The pattern used to be year followed by the month, but we decided to change it to a more straightforward major/minor system starting from 2.2. This is because the parallel development on several branches made it infeasible to classify the releases simply by their real release dates. If you are making a port now, you do not have to worry about old -CURRENTs; they are listed here just for your reference.
