This release adds a few minor features and fixes a
few minor bugs. The new features include drawing
of wavy lines that are used to depict the
attachment point of a fragment, many more paper
sizes, better handling of parts of a drawing that
accidentally get out of the paper, and 2D rotation
of arrows. Windows binary packages now include PDF
export via Cairo.
This release fixes a nasty regression in hydrogen
positioning that was
introduced in the last release. It also features a
new icon contributed
by Jakub Szypulka.
