| Changes since the last public release (1.4.0): |
| |
| version 1.4.1 [February 25, 2010] |
| |
| Updated CMakeLists.txt for consistent indentation and to avoid an |
| unclosed if-statement warning (Philip Lowman). |
| Revised Makefile.am and Makefile.in to remove references to Y2KINFO, |
| KNOWNBUG, and libpng.la (Robert Schwebel). |
| Revised the makefiles to install the same files and symbolic |
| except for libpng.la and libpng14.la. |
| Make png_set|get_compression_buffer_size() available even when |
| PNG_WRITE_SUPPORTED is not enabled. |
| Revised Makefile.am and Makefile.in to simplify their maintenance. |
| Revised the makefiles to install a link to libpng14.so.14.1 |
| Removed png_set_premultiply_alpha() from scripts/*.def |
| Revised png_decompress_chunk() to improve speed and memory usage when |
| decoding large chunks, using a two-pass method suggested by John Bowler. |
| Added png_set|get_chunk_malloc_max() functions. |
| Relocated "int k" declaration in pngtest.c to minimize its scope. |
| Folded some long lines in the source files. |
| Added defineable PNG_USER_CHUNK_CACHE_MAX and PNG_USER_CHUNK_MALLOC_MAX |
| Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as |
| png_ptr->png_user_chunk_malloc_max. |
| Return allocated "old_buffer" in png_push_save_buffer() before calling |
| png_error(), to avoid a potential memory leak. |
| Removed the cbuilder5 project, which has not been updated to 1.4.0. |
| Complete rewrite of two-pass png_decompress_chunk() by John Bowler. |
| Removed obsolete unused MMX-querying support from contrib/gregbook |
| Removed the AIX redefinition of jmpbuf in png.h |
| Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt |
| when using AIX compiler. |
| Removed unused gzio.c from contrib/pngminim gather and makefile scripts |
