([#38](https://github.com/diagrams/diagrams-cairo/issues/38))
1.0.1.2 (6 February 2014)
-------------------------
- Require diagrams-lib >= 1.0.1
1.0.1.1: 30 January 2014
------------------------
- Work around bug in GHC 7.4.2, which can't derive Generic for associated
data types.
1.0.1: 26 January 2014
----------------------
- Add `Hashable (Options Cairo R2)` instance
1.0: 25 November 2013
---------------------
- Re-implement via new backend `RTree` interface.
- Use new command-line interface from `diagrams-lib`.
- Export `B` as an alias for `Cairo` token.
0.7: 9 August 2013
------------------
* **New features**
- New `renderCairo` function for more convenient use of the cairo
backend.
- Lots of Haddock documentation improvements.
* **New instances**
- `Show` instance for `Options Cairo R2`.
0.6: 11 December 2012
---------------------
* **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.
* **Dependency/version changes**
- Upper bounds relaxed to allow
`base`-4.6, `unix`-2.6, `cmdargs`-0.10, `split`-0.2.*, `mtl`-2.1
- Add a dependency on `time`, and conditional compilation to use
either ClockTime or UTCTime depending on the version of the
`directory` package
- Add dependency on `colour`
- Lower bound on `cairo` raised to 0.12.4
* **Bug fixes**
- Fixed looped compile mode, which was repeatedly trying to compile
when the code contained errors, instead of trying once and then
waiting for a change.
- Fix a bug where default attributes were not being set when using
the "bypass" mode used by the gtk backend. ([\#16](https://github.com/diagrams/diagrams-cairo/pull/16))
0.5.0.2 : 13 May 2012
---------------------
* Allow building under `mtl` 2.1.*
0.5.0.1 : 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`.
0.5: 9 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**
- [\#54](http://code.google.com/p/diagrams/issues/detail?id=54): Generate warning for missing image files (Ian Ross).
0.4: 22 October 2011
--------------------
* New features:
+ Support for drawing directly to Gtk widgets
+ Support for path fill rule attribute
* New/improved examples
* Improved documentation
* Bug fixes:
+ Warning for unsupported image types (#41)
0.3: 18 June 2011
-----------------
* Some new/improved examples
* New features:
+ simple text support
+ simple support for external PNG images
0.2: 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
0.1.2: 18 May 2011
------------------
* link to new website
