From Steve Schoger’s announcement tweet:

🤩 All new look! 260 icons redrawn from scratch
🤏 Thinner 1.5px stoke
✨ New 24px solid set

Available as first-party React and Vue libraries and official Figma components.

The React and Vue libraries are cool, but the coolest part about SVG-based icons is how you can simply copy/paste the HTML directly into your code.
