* dropped support for Python 2.6, added support for Python 3.4
* dropped support for OpenJPEG versions 1.3 and 1.4
* dropped windows support (it might work, it might not, I don't much care)
* added write support for JP2 UUID, dataEntryURL, palette, and component mapping boxes
* added read/write support for JPX free, number list, and data reference boxes

Glymur 0.6 works on Python versions 2.7, 3.3 and 3.4. If you have Python 2.6,
you should use the 0.5 series of Glymur.
OpenJPEG Installation
=====================
Glymur will read JPEG 2000 images with versions 1.3, 1.4, 1.5, 2.0,
and the trunk/development version of OpenJPEG. Writing images is
only supported with the 1.5 or better, however, and the trunk/development
version of OpenJPEG is strongly recommended. For more information about
OpenJPEG, please consult http://www.openjpeg.org.
If you use MacPorts or if you have a sufficiently recent version of
Linux, your package manager should already provide you with a version of
OpenJPEG 1.X which glymur can already use.
For more information about OpenJPEG, please consult http://www.openjpeg.org.
