Detect default parameters

[gregsdennis]

A method with a new default parameter shouldn't be a breaking change, but rather it should be regarded as a new overload. Thus the suggested bump should be minor, not major.

I'm not sure how to do this one. It doesn't seem that the reflection library we're using captures whether a parameter has a default or not.

Additionally, I'm not sure that this really isn't a major bump because of how default parameters work. Eric Lippert has a good post describing this behavior and illustrates why this probably should be a breaking change.

Changing a default from false to true is a breaking change, and one could argue that existing callers should be insulated from that breaking change.

I think the system might be correct here, though it wouldn't pick up on a changed default.
