Released on January 25, 2013.
- Fixed a bug that :meth:`Image.transparentize()
<wand.image.Image.transparentize>` method (and :meth:`Image.watermark()
<wand.image.Image.watermark>` method which internally uses it) didn't
work.
- Fixed segmentation fault occurred when :attr:`Color.red
<wand.color.Color.red>`, :attr:`Color.green <wand.color.Color.green>`,
or :attr:`Color.blue <Wand.color.Color.blue>` is accessed.
- Added :attr:`Color.alpha <wand.color.Color.alpha>` property.
- Fixed a bug that format converting using :attr:`Image.format
<wand.image.Image.format>` property or :meth:`Image.convert()
<wand.image.Image.convert>` method doesn't correctly work
to save blob.
