• version #4.8.0
• components: Button

So bootstrap 4 has finally moved from alpha to beta, and with it they have dramatically changed the default colour palette. Most notably they have changed the btn-secondary css class from a white color to a dark grey, which doesn't seem like a good default for a button. Unfortunately, "secondary" is the default prop for the reactstrap Button class. I recommend making the default for the Button class to be just the bootstrap btn css class or btn-light css class, because otherwise I imagine that it might become necessary to explicitly give a color prop to almost every instance of Button.
