ChangeLog
---------
0.6.0 (pending)
===============
* Added Cinema2K, Cinema4K write support.

Package Management Suggestions
''''''''''''''''''''''''''''''
You only need to read this section if you want detailed
platform-specific instructions on running as many tests as possible or wish to
use your system's package manager to install as many required
packages/RPMs/ports/whatever without going through pip.
Mac OS X
--------
All the necessary packages are available to use glymur with MacPorts.
For python 3.3, you should install the following set of ports:
* python33
* py33-numpy
* py33-lxml
* py33-distribute
* py33-Pillow (optional, for running certain tests)
MacPorts supplies both OpenJPEG 1.5.0 and OpenJPEG 2.0.0.
Linux
-----
For the most part, you only need python and numpy to run glymur, so on
just about all distributions you are already set to go (and you don't
need to mess around with a configuration file, as the openjpeg shared
libraries are found in the usual places thanks to your package manager).
In order to run as many tests as possible, however, the following Python
packages may also need to be installed. Consult your package manager
documentation or use pip.
* setuptools
* python-lxml
* matplotlib
* pillow
* contextlib2 (2.7 only)
* mock (2.7 only)
Glymur 0.6 been tested on the following linux platforms without any unexpected
difficulties:
* OpenSUSE 13.1
* Fedora 19
* Raspian
* Travis CI (currently Ubuntu 12.04?)
Windows
-------
The 0.6.x series of Glymur is untested on windows and I make no promises here.
I suggest that windows users check the 0.5.x series.

tests. data for the purpose of configuring and running OpenJPEG's test
suite. Check their instructions on how to do that. You can then
set the **OPJ_DATA_ROOT** environment variable for the purpose of
pointing Glymur to OpenJPEG's test suite. ::
* **OPJ_DATA_ROOT** - points to directory for OpenJPEG test data (see above) $ svn co http://openjpeg.googlecode.com/svn/data
* **FORMAT_CORPUS_DATA_ROOT** - points to directory for format-corpus repository (see https://github.com/openplanets/format-corpus if you wish, but you really don't need to bother with this) $ export OPJ_DATA_ROOT=`pwd`/data
Setting these two environment variables is not required, as any tests using
either of them will be skipped.

Quite a few tests are currently skipped. These include tests whose
OpenJPEG counterparts are already failing, and others which do pass but
still produce heaps of output on stderr. Rather than let this swamp
the signal (that most of those tests are actually passing), they've been
filtered out for now. There are also more skipped tests on Python 2.7
than on Python3. The important part is whether or not any test
errors are reported at the end.

=====================
Changes in glymur 0.5
=====================
Changes in 0.5.12
=================
* Minor documentation fixes for grammar and style.
* The functions removed in 0.5.11 due to API changes in OpenJPEG 2.1.0 were
restored for backwards compatibility. They are deprecated, though, and will
be removed in 0.6.0.
* ``glymur.lib.openjp2.stream_create_default_file_stream_v3``
* ``glymur.lib.openjp2.opj.stream_destroy_v3``
Changes in 0.5.11
=================
* Added support for Python 3.4.
* OpenJPEG 1.5.2 and 2.0.1 are officially supported.
* OpenJPEG 2.1.0 is officially supported, but the ABI changes introduced by
OpenJPEG 2.1.0 required corresponding changes to glymur's ctypes interface.
The functions
* ``glymur.lib.openjp2.stream_create_default_file_stream_v3``
* ``glymur.lib.openjp2.opj.stream_destroy_v3``
functions were renamed to
* ``glymur.lib.openjp2.stream_create_default_file_stream``
* ``glymur.lib.openjp2.opj.stream_destroy``
in order to follow OpenJPEG's upstream changes. Unless you were using the
svn version of OpenJPEG, you should not be affected by this.
Changes in 0.5.10
=================
* Fixed bad warning issued when an unsupported reader requirement box mask
length was encountered.
Changes in 0.5.9
================
* Fixed bad library load on linux as a result of botched 0.5.8 release.
This release was primarily aimed at supporting SunPy.
