ChangeLog

aaphoto Changelog:
--------------------
2010/07/18 - aaphoto v0.38 - additional verbose message showing presence of alpha channel in PNG images
                           - bugfix: fix compile with only BMP support
                           - fix some warning messages during build
                           - removing unnecessary __WIN32__ macro
2010/05/10 - aaphoto v0.37 - OpenMP support added for multi processing, all possible time intensive codes paralleled
                             __OPENMP__ directive and -fopenmp option are needed at compile time (supported since GCC v4.2)
                             (not available on windows platform yet)
                           - new -t, --threads switch added for manually setting the number of working threads
                           - new aaRGB v0.61 version update
                           - bugfix: exif info was missed out after last version's change in JPEG handling
                           - improvement in exif handling and verbose messages
                           - refining additional verbose messages
                           - removing pgx file type support because it is outdated
                           - some changes in documentation
                           - some minor code cleanup and bugfixes
2010/03/16 - aaphoto v0.36 - bugfix: fix for tmpfile() patches of libjasper and libjpeg (windows platform only)
                             when running more than one instances of aaphoto at a time, they all used the same
                             temporary files and therefore the images became corrupt
                           - bugfix: it doesn't ask for administrative privileges anymore while running in an admin account
                             under vista and windows 7 (windows platform only)
                           - bugfix: the --rotate180 switch didn't turn the middle line in images with odd heights
                           - JPEG format handling entirely rewritten to be able to handle extra parameters in this format
                             separately, now libjpeg is used directly instead of libjasper for reading / writing JPEG images
                             so libjpeg is a new dependency from now on, formerly only libjasper was depended on it
                           - original DPI values of images are restored in BMP, JPEG and PNG formats during conversion
                           - refining program messages
                           - printing the time elapsed in seconds since program start in verbose mode if not zero
                           - printing extra info of bitmap dimension, resolution and color depth in verbose mode
2010/02/25 - aaphoto v0.35 - bugfix: possible buffer overflows fixed
2010/02/19 - aaphoto v0.34 - __UNIX__ macro removed from Makefile, not needed anymore
                           - bugfix: static binary update with patches of libjasper and libjpeg
                             1) sleep() function missing on mingw32 platform
                             2) bad implementation of tmpfile() function on windows platform
                                it tries to create temporary files in the root of current directory
                                instead of the system temporary path so that causes failure for unprivileged users
                                who don't have permissions to write there
                           - update: changes in new version of libpng 1.4.0, aaio.c updated as necessary
                                png_check_sig() function replaced with png_sig_cmp()
                                setjmp(png_ptr->jmpbuf) has been deprecated, changed to setjmp(png_jmpbuf(png_ptr))
                                see more at http://www.libpng.org/pub/png/src/libpng-1.2.x-to-1.4.x-summary.txt
2010/01/10 - aaphoto v0.33 - some changes in documentation
                           - bugfix: unfreed space caused memory leak
                           - bugfix: uninitialized variable caused --resize to misbehave
                           - fix: change of return values in procedures to reflect standard exit codes
                             now it has a sense to run something like "aaphoto image.jpg && echo OK"
                             formerly return codes meant opposite
                           - fix a warning message during compile time, an include was missing
                           - boundary check of fixed size arrays added for safety reasons
                           - the --speed switch removed, it made the code less platform independent and was fussy anyway
                           - error messages printed to stderr instead of stdout from now
                           - more verbose error message on failure of image load

                           - bugfix: length of exif info was determined wrongly
                           - rework of the parameters and switches parsing part
