From the announcement:
First, a huge thank you to Jamie Folsom and Andy Stuhl from Perfomant Software Solutions LLC, who did the heavy lifting on the coding for this release. We couldn’t have done it without them. We’re grateful, as well, to Neatline community member Adam Doan (@doana on Github) from the University of Guelph, whose code contributions made Neatline’s first accessibility functionality possible.
