Version 0.19 (2020 September 10) * API change to use full 32 bit segment numbers, in accordance to the JBIG2 specification. * Better handling of end of input data stream and and when encountering errors in the arithmetic decoder stream. This should improve many situations where jbig2dec appeared to run forever. * Fix several bugs related to signedness or over-/underflow checks that were not robust. * Bug fixes for issues reported by Coverity/OSS-fuzz. * Add option to limit memory usage to command line tool. * Update manpages, and command line tool usage. Version 0.18 (2020 February 11) * Performance enhancements related to decoding of MMR and generic regions as well as composing images onto pages. * Bug fixes for a few issues reported by Coverity and OSS-Fuzz. Version 0.17 (2019 September 16) * Improved test suite by verifying input file contents and adding all ubc test streams. Fixed bugs where previously missing ubc test streams were decoded incorrectly. * Bug fixes for a few issues reported by Coverity. * Moved version number to jbig2.h, and adapted configure correspondingly. Added pkg-config file to be installed along side library. Version 0.16 (2019 April 04) * API change allowing for library users to get the custom allocator so it may be freed if necessary. This is useful if the allocator is extended with e.g. a custom pointer needed by the allocator callbacks. Version 0.15 (2018 September 04) * Bug fix release, with many security related and stability fixes as well as better tolerance/behaviour with out of spec files Version 0.14 (2017 October 04) * Bug fix release. Version 0.13 (2016 April 07) * Bug fix release. Version 0.12 (2014 October 1) * Bug fix release. Version 0.11 (2010 February 2) * Support for generic regions with typical prediction (042_8.jb2) * Correct bitmap offsets with transposed text (042_19.jb2) * Autotools build now uses libtool and provides a shared library * Manpage for jbig2dec * Code cleanup and robustness fixes Version 0.10 (2009 May 28) * Security fix for malicious symbol dictionaries CVE-2009-0196 * Fix various resource leaks and error handling issues * Dynamically allocate huffman symbol length histogram to save space * Support aggregate symbol coding * Work around invalid Xerox WorkCentre streams which write the final segment length as -1 * Fix an issue with huffman table runcodes Version 0.9 (2006 July 27) * striped page support * successfully decodes ubc test streams 042_9, 042_20 Version 0.8 (2005 April 6) * Fix an allocation error in the page array * properly handle non-OR image composition operators * Fix a UMR bug in the compositor * successfully decodes ubc test streams 042_12,15,16,17,18 * various memory leak fixes Version 0.7 (2004 December 8) * properly initialize page buffers * refinement region handling * successfully decodes ubc test streams 042_21, 042_22 and 042_23 * generic region template 3 handling with arbitrary AT locations * successfully decodes ubc test streams 042_6 and 042_7 Version 0.6 (2003 December 31) * minor portability fix for cygwin Version 0.5 (2003 December 4) * compiler warning fixes * Properly handle the export specification for symbol dictionaries. * successfully decodes multipage documents from the Adobe encoder. Version 0.4 (released 2003 August 1) * redid license header to simplify relabelling for commercial distribution, borrowing from Ghostscript. Version 0.3 (released 2003 May 20) * win32 portability fixes related to ghostscript integration * generic mmr region support * successfully decodes ubc test stream 042_3 Version 0.2 (released 2003 April 17) * portability fixes * support for metadata extension segments (latin-1 only) * decodes single-page documents from the Adobe encoder * various other bugfixes Version 0.1 (released 2002 August 6) * decodes artithmetic and huffman-coded generic regions - some templates not working * decodes arithmetic symbol dictionaries * decodes artithmetic text regions * successfully decodes ubc test streams 042_1,2,4,5 and 10. * successfully decodes CVision embedded bitstream str-p39 * regression testing harness based on SHA-1 hashes of known files
