1.0: 25 November 2013

• New features

  • New module Diagrams.TwoD.Sunburst, for drawing sunburst charts.
  • New module Diagrams.TwoD.Path.Metafont, for specifying trails/paths using an API inspired by Metafont. Like cubicSpline but gives you control over things like the tension/curvature or the tangent at a given point.
  • New module Diagrams.TwoD.Path.Calligraphic for making simple "calligraphic" strokes.
  • New module Diagrams.Lens with lenses for working with diagrams.

• Bug fixes

  • Diagrams.TwoD.Factorization.primeLayout has been rewritten to avoid iterated transformations, giving a significant performance boost.

0.7: 9 August 2013

• New features

  • New module Diagrams.Color.HSV with an hsvBlend function for blending colors in HSV space.

  • Diagrams logo code is now in Diagrams.Example.Logo.

  • New symmetric layout algorithm for binary trees in Diagrams.TwoD.Layout.Tree.

• Bug fixes

  • Fix a bug in Diagrams.TwoD.Path.Turtle which sometimes caused it to output a doubled path (#13).

0.6.1 (23 March 2013)

• New features

  • New Diagrams.TwoD.Path.IteratedSubset module, for constructing paths using an "iterated subset" algorithm (repeatedly replacing segments with a given path).

  • New Diagrams.TwoD.Layout.CirclePacking module for circle-packing layout

  • New Diagrams.TwoD.Factorization module, for creating "factorization diagrams" as seen at http://mathlesstraveled.com/2012/11/05/more-factorization-diagrams/ and on the cover of Hacker Monthly (http://mathlesstraveled.com/2012/10/05/factorization-diagrams/).

  • Diagrams.TwoD.Path.Turtle: generalize runTurtle function, and add new functions drawTurtle and sketchTurtle. drawTurtle results in a diagram (like the old runTurtle), and sketchTurtle yields a path (ignoring pen style commands).

• Documentation

  • Added lots of example images using diagrams-haddock

  • The type of renderTree is generalized to work with any QDiagram b R2 m.

• Bug fixes

  • Tiling generation code in Diagrams.TwoD.Tilings wasn't actually checking whether vertexes had been already visited.

• Dependency/version changes

  • Switch from fclabels to lens
