It sucks so badly.<p>They made it incompatible with version 4, and removed many names that people are used to to "clean up the code".<p>They put their needs ahead of their users', and that sucks.
Personally, I love it. I've had an extremely pleasant experience during the Pro-backer "beta" program and look forward to additional updates. Granted, I'm using the SVG framework provided by the NPM package import only the required icons into a reusable React component. The new NPM framework supports tree-shaking so it's nice to not have to include all of the icons if I'm not even using them.
