Version History:
----------------

Release 0.95
------------

 * Added more unit tests around BMP.
 * Added more images to the test image suite.
 * Fixed a bug where errors were being wrongly logged to System.out.
 * Moved the example code into the test source directory, to comply with Maven's standard project layout.
 * Added a couple of images to the sample image library that demonstrate a couple variations on Photoshop/IPTC data.  
 * Fixed a small bug in the IPTC constants introduced while cleaning up the constants.
 * Started shift towards moving field-level parsing into BinaryInputStream and BinaryOutputStream.
 * Fixed a png unit test that used a piece of Java 1.6 syntax.
 * Added unit tests around the new IPTC functionality.
 * Added IPTC remove/update/insert functionality.
 * Rewrote the IPTC parsing support.  
 * Added improved support for reading and writing iTXt, tEXt, zTXt Png chunks.
 	Added a unit test that demonstrates the feature.
 * Found a new regression wherein DeflaterOutputStream needs to be closed.
 * Added the .tar.bz2 distributions back into the maven assembly descriptors.
 * Moved the example/sample code to a new top-level source folder, "example."
 * Replaced dependency on java.util.zip.DeflaterOutputStream, which is only available in Java 1.6.
 * Added a unit test around reading and writing images in every format.
 * We now sort some (but not all) GIF color tables.
 * Applied the BMP "buffer flushing" bug to the PBM reading and writing code.
 * Fixed a regression around flushing the bit buffer when writing BMPs with very small palettes.
 * Removed assumption about DataBuffer type when reading BMPs.
 * When writing a GIF, we now always include a Graphic Control Extension block, even if its not necessary.
 * We are more defensive about missing GCEs.
 * Lastly, we now set a minimum bound on initial code sizes for LZW-compressed Gif image data.
 * Found a regression in writing TIFFs around strip offsets being properly updated.  Not a LZW issue after all.
	Added a few unit tests around this issue.
