Well because that is a recent change and I didn't know about it and
I missed it while browsing the documentation. I think this kind of
documenation should be part of the proper description and not part
of the history.

It also doesn't work for everything. Logger.isEnabledFor(lvl)
expect a number.

But for the moment it serves my needs, so thanks for pointing it out.
