This page describes breaking API changes between diagrams 1.1 and 1.2, along with explanations of how to migrate to the new 1.2 API.

Attributes using Measure

LineWidth is now specified using Measure. This replaces former uses of freeze. See the manual for full details. The old behavior of lw (in diagrams not using freeze) can be had by using lwL.

However, in many simple cases, we recommend instead using named line weights provided in Diagrams.TwoD.Attributes. These include thin, thick</code, and none.

Arrows

The size of arrow heads and tails is now specified in terms of length instead of the radius of their circumcircle.

Gaps at the ends of arrows are now specified using Measure R2.

The gap traversal has been replaced by `gaps` for consistency in naming, though gap is still provided for backwards compatibility.

Reorganization

The avgScale function has been moved from Diagrams.TwoD.Transform to Diagrams.Core.Transform.

Most (all?) 2D attributes have been moved from Diagrams.Attributes to Diagrams.TwoD.Attributes.

The Angle definition and related functions have moved to a separate module, Diagrams.Angle.
