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 merely by their real release dates. Do not worry about old -CURRENTs; they are listed here just for reference.
