Version 2.0.0 includes a few changes that may affect the appearance of the "Pin It" button on your website.
It is now only providing features that are supported in the official "Pin It" button from Pinterest.
Additional features can be found in "Pin It" Button Pro.
"Pin It" Button Lite has also been rewritten to be in full compliance with the current "Pin It" button developer guidelines.
Finally, all references to "!important" in the public CSS to allow for more control of styles. You may need to add or remove custom CSS to improve the layout and styling of the button.
