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`

0.6.0.4 (19 March 2013)
-----------------------

* bump upper bound to allow QuickCheck-2.6

0.6.0.3: 27 January 2013
------------------------

* Switch to explicit import list for Control.Lens to avoid name conflicts

0.6.0.2: 24 January 2013
------------------------

* Require lens-3.8

0.6.0.1: 17 December 2012
-------------------------

* Update dependencies of tests

0.6: 11 December 2012
---------------------

* **New features**

    - New pure implementation of Turtle library, in `Turtle.Internals`

    - `Diagrams.TwoD.Layout.Tree`:

	- New `renderTree'` function which gives
	  the edge-drawing function access to the values stored at the
	  nodes instead of just the node positions.

	- 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`

0.1.1.1: 13 May 2012
--------------------

* bump `mtl` (< 2.2) and `data-default` (< 0.5) upper bounds

0.1.1.0: 16 March 2012
----------------------

* Add Andrew Kennedy's symmetric rose tree layout algorithm to
    `Diagrams.TwoD.Layout.Tree`

0.1.0.0: 9 March 2012
---------------------

Initial release, containing:

* `Diagrams.Layout.Wrap`, for laying out diagrams "wrapped" inside an
    arbitrary region (Michael Sloan)

* `Diagrams.TwoD.Tilings`, for generating various 2D regular tilings
    (Brent Yorgey)

* `Diagrams.TwoD.Apollonian`, for generating Apollonian gaskets (Brent
    Yorgey)

* `Diagrams.TwoD.Layout.Tree`, tree layout and drawing algorithms
    (Brent Yorgey)

* `Diagrams.TwoD.Path.Turtle`, creation of 2D paths using a stateful
    "turtle" interface (Michael Sloan)
