I have decided that LGPL is overkill for a tiny project like unFocus.HistoryKeeper (and friends) – so I changed it to MIT. LGPL would have been a pain for anyone selling or using a commercial product with history keeper, and I really don’t think the code is substantial enough to be such a headache. But now that’s not a problem! MIT is a better fit I think.
The change has already been reflected on the Google Code page, and in the newest release archive.
