Please do no use 0.01.
Regardless of issues such as the applicability and mapping of "stable API",
"added feature", "bug fix" etc to a license text, I do think that
http://semver.org/ summarizes well today's general expectations of a
version number.
In particular, points are not decimal points, they are separators between
non-negative integers, such that 0.10.0 > 0.2.0.
So, please do not use 0.01; 0.0.0 or 0.1.0 is better.
This is my strong opinion on the color of this particular wall of the bike
shed.
I am inclined to follow this suggestion. I think the first numbered
release should be "0.1.0".
