The Chebfun team is pleased to announce the release of Chebfun v5.5.0. This release introduces Chebfun3 for computation in a 3D box, due to Behnam Hashemi. To learn about Chebfun3 see the users guide and the examples. To get the new version, go to the download page or GitHub.

Chebfun v5.5.0 also offers SPIN3 for stiff PDEs in 3D, SUMDISK for integrating bivariate functions over a disk, and EXPLAIN for seeing in detail how the Chebfun constructor chops a Chebyshev series.

We hope you enjoy the new release. Feel free to post any questions or comments to the Chebfun users' group chebfun-users.
