+* [antonin] openjpeg.c : fixed initialization of parameters->cp_disto_alloc/fixed_quality/fixed_alloc/tcp_numlayers because they were preventing to use the -q and -f options.
+
+August 31, 2009
+* [antonin] JavaOpenJpegDecoder.c : fixed a signed/unsigned behaviour when returning form C to JAVA
+
+August 21, 2008
+* [antonin] found a bug in tcd.c that was preventing to find the correct threshold in tcd_rateallocate.c for high-precision images. Applied a temporary patch but a better solution should be found.
+
+August 21, 2008
+* [antonin] fixed a bug in image_to_j2k.c that was preventing the 'r' option to work properly (everything was compressed lossless regardless of the specified rate).
+
+August 8, 2008
+! [FOD] Modified the way raw images with more that 8bpp are read and written
+
+July 9, 2008
++ [Parvatha] Added the default lossless parameter to opj_set_default_encoder_parameters in openjpeg.c.
+
+June 12, 2008
+* [antonin] fixed a bug in dirent.h that prevented codec on Linux Alpha Systems to compile correctly. Thanks to RobinC.
+
+May 22, 2008
+* [antonin] fixed a bug in j2k.c (j2k_write_sod) that allowed to get negative rates, thanks zhong1985624 for pointing this.
+
+May 22, 2008
+* [antonin] additional test to avoid crash due to invalid image size, patch by Christopher Layne
+
+May 20, 2008
+* [antonin] memory leak fixed in openjpeg.c (opj_destroy_cstr_info()), patch by Carsten Juttner
+
+March 12, 2008
++ [GB] help line for the -F option in j2k_to_image
+
+March 4, 2008
+! [FOD] Changed Java files copyright in JavaOpenJPEG module
+
+February 28, 2008
+* [FOD] Fixed openjpeg.c for proper initialization of codec context structures (dinfo in opj_create_compress()
+ and opj_create_decompress(). Bug fix suggested by Andrey V. Kiselev
+* [FOD] Clean up of opj_aligned_malloc(), to just forgo the use of posix_memalign(),
+ as apparently memalign() is what is working better for everyone. Patch by Callum.
+
+February 28, 2008
+- [FOD] Removed the J2KViewer module, which has been replaced by OPJViewer
+* [FOD] Fixed the error handling of j2k_decode in jp2.c, thanks to Robin Cornelius
+
+February 11, 2008
+* [GB] Minor style modifications to comply with c99 compiler flag; removed Microsoft-specific "union-in-struct" syntax; Re-enabled cstr_info struct creation when -W switch is specified
+! [GB] Changed a number of things in opjviewer (e.g., decoding thread does not execute GUI calls anymore), to have it running under linux --> it is better than before, but still crashes
+
+February 5, 2008
+! [Parvatha] In convert.c, corrected imagetobmp() conversion for grayscale. In tcd.c, corrected Rate modification in
+ tcd_init_encode(). Thanks to Jeremy Furtek and J�r�me Fimes.
+
+January 31, 2008
+! [GB] In opjviewer, unification of JPEG 2000 family handlers (*.jp2, *.mj2, *.j2k) in a single file
+
+January 22, 2008
+! [FOD] In image.c, changed the opj_image_create0() memory allocation from malloc() to calloc() in order
+ to avoid segfaults when freeing the memory allocated for the coding of bad images.
+ Thanks to Christopher Layne for this improvement.
+
+January 17, 2008
++ [antonin] Initial commit of Xcode project directory (XCode 2.5 for macosx)
+ available targets : libopenjpeg (stat and dyn), image_to_j2k, j2k_to_image
+
+January 16, 2008
+* [antonin] fixed opj_malloc.h for macosx (bugfix provided by janpeder, thanks)
+
+January 11, 2008
++ [FOD] Added missing files to JavaOpenJPEG project (files from Patrick Piscaglia)
+
+January 4, 2008
+* [Parvatha] Patch by Callum Lerwick. Fixed bug during encoding using tile option in tcd.c

+December 21, 2007
+VERSION 1.3.0 RELEASED
+----------------------
+
+December 21, 2007
+* [FOD] Bug fixed by David Bruken. Fixed memory allocation issue in opj_malloc.h
+! [FOD] Possible errors in pi_create_encode handled
+
+December 19, 2007
+* [Antonin] changed variables names alpha, beta, gamma, delta in dwt.c to avoid re-declarations on Macosx
+! [Parvatha] In pi.c, removed the Recursive function pi_check_next_level() and modified the code.
+* [FOD] Fixed allocation problem in pi.c
+
+December 19, 2007
++ [FOD] In mqc.h, changed MQC_NUMCTXS from 32 to 19 as there are only 19 possible contexts
+
+December 10, 2007
++ [FOD] First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by Patrick Piscaglia of Telemis (www.telemis.com).
+ Thank you Patrick for this new module !
+
+November 29, 2007
+! [GB] Added index.h and index.c in VC6 projects; wrapped index.h in the C++ preprocessor; modified OPJViewer project and some files.
+
+November 14, 2007
++ [FOD] Created the file index.c in the codec directory. This file handles the creation of index files,
+ at encoding and decoding.
+* [FOD] Fixed bugs during the creation of the index (PCRL progression order)
+* [FOD] Fixed the maximum number of resolutions a user can discard while decoding.
+ Added an error state in J2K_STATE (j2k.c)

-! [FOD] First Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c
- Second Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as
+! [FOD] - First Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c
+ - Second Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as
late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.
+ - Third Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it
+ contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates
+ the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size
+ them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate
+ encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.
+
+* [FOD] Avoided ABI breakage
