**New features**

- New `--list` option for `multiMain` to list all available diagrams

- Major documentation improvements

- New modules:

  + `Diagrams.Backend.Cairo.Ptr`, for rendering directly to buffers
    in memory

  + `Diagrams.Backend.Cairo.List`, for rendering to a list of lists
  of pixels.

**API changes**

- Removal of `StyleParam` from `Diagrams.Backend.Cairo.Text`, change
  functions in that module to accept `Style R2`.  Usage can be fixed
  by applying these style functions to `mempty`.

- GTK rendering has been split out into a new package, diagrams-gtk.

+ The `Diagrams.Backend.Cairo.Gtk` module is now
  `Diagrams.Backend.Gtk` in the `diagrams-gtk` package.

+ The `CairoOptions` record has a new boolean `cairoBypassAdjust`
  option; when set, the backend should bypass calling `adjustDia2D`.

+ The GTK output type is gone.

+ There is a new `RenderOnly` output type, for when you don't
  care about the `IO` action but only want the cairo `Render` action.

**Fixed bugs:**

- old-time and 7.6 [\#21](https://github.com/diagrams/diagrams-cairo/issues/21)

- Use of deprecated 'try' function in Diagrams.Backend.Cairo.Internal [\#12](https://github.com/diagrams/diagrams-cairo/issues/12)

- Attribute transformations are not handled correctly when rendering [\#3](https://github.com/diagrams/diagrams-cairo/issues/3)

**Closed issues:**

- vector-space-0.8.5 breaks compilation [\#27](https://github.com/diagrams/diagrams-cairo/issues/27)

- ‘cairoBypassAdjust’ undocumented [\#23](https://github.com/diagrams/diagrams-cairo/issues/23)

## [v0.5.0.2]() (13 May 2012)

* Allow building under `mtl` 2.1.*

## [v0.5.0.1]() (9 March 2012)

* Remove statement in package description that a development version
    of `gtk2hs` must be used with GHC 7.4; this is no longer true as of
    the 0.12.3 release of `gtk2hs`.

## [v0.5]() (March 2012)

**New features**

- New `Diagrams.Backend.Cairo.Text` module by Michael Sloan, with
  functions for creating appropriately sized text objects by
  querying cairo for the size, and related supporting functions.

- Basic support for animation with `animMain` function, by
  generating frames sampled at regular intervals.

- Proper vertical alignment of default text based on font
  parameters (Michael Sloan).

- Requesting just a width or height now causes the other to be
  computed appropriately.

**API changes**

- Move `Diagrams.Backend.Cairo` to
  `Diagrams.Backend.Cairo.Internal` and export everything.
  `Diagrams.Backend.Cairo` now just re-exports selected functions
  from `Internal`.  This allows anyone who wants access to the
  helper/utility functions to import `Internal`.

**Dependency/version changes**

- relax `cmdargs` upper bound

- GHC 7.4.1 compatibility: update `base`, `filepath`, and
  `old-time` upper bounds

**Bug fixes**

## [v0.2]() (3 June 2011)

* add `Typeable` and other instances for `Cairo` type

* generalize `Result` type to `(IO (), Render ())`, so programs that
    don't want to generate a file but just want a `Render` operation
    (*e.g.* to use to paint a gtk window) can use the second component.

* add support for opacity attribute and path clipping

## [v0.1.2]() (18 May 2011)

* link to new website

## [v0.1.1]() (18 May 2011)
