+<h4>Showing some love for our contributors!</h4>
 <p>We recently sent out gratitude envelopes to some of our most active community members as a small but heartfelt recognition of their dedication and support. And for our many community members who did not get an envelope, thank you! We appreciate everything you do for us. If you are looking for a way to help spread the appreciation, you can <a href="https://github.com/sponsors/Ultimaker">become a Cura sponsor on GitHub</a>.</p</p>
