[P]innate
Pinnate (v0.4.1) is the first candidate release for v1.0.0. The language has become relatively stable and is unlikely to change much until a release is selected for v1.0.0.
Massive changes have been made to Coconut since Odisha (v0.3.6). If you've been following Coconut development, you should read the new tutorial and go over the new documentation to familiarize yourself with all the changes.
Pinnate is the type of leaf on the Coconut palm.
