| Changes since the last public release (1.6.2): |
| |
| Version 1.6.3beta01 [April 25, 2013] |
| Revised stack marking in arm/filter_neon.S and configure.ac. |
| Ensure that NEON filter stuff is completely disabled when switched 'off'. |
| Previously the ARM NEON specific files were still built if the option |
| was switched 'off' as opposed to being explicitly disabled. |
| |
| Version 1.6.3beta02 [April 26, 2013] |
| Test for 'arm*' not just 'arm' in the host_cpu configure variable. |
| Rebuilt the configure scripts. |
| |
| Version 1.6.3beta03 [April 30, 2013] |
| Expanded manual paragraph about writing private chunks, particularly |
| the need to call png_set_keep_unknown_chunks() when writing them. |
| Avoid dereferencing NULL pointer possibly returned from |
| png_create_write_struct() (Andrew Church). |
| |
| Version 1.6.3beta05 [May 9, 2013] |
| Calculate our own zlib windowBits when decoding rather than trusting the |
| CMF bytes in the PNG datastream. |
| Added an option to force maximum window size for inflating, which was |
| the behavior of libpng15 and earlier. |
| Added png-fix-itxt and png-fix-too-far-back to the built programs and |
| removed warnings from the source code and timepng that are revealed as |
| a result. |
| Detect wrong libpng versions linked to png-fix-too-far-back, which currently |
| only works with libpng versions that can be made to reliably fail when |
| the deflate data contains an out-of-window reference. This means only |
| 1.6 and later. |
| Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning |
| message which it is easier to work round than ignore. |
| Updated contrib/pngminus/pnm2png.c (Paul Stewart): |
| Check for EOF |
| Ignore "#" delimited comments in input file to pnm2png.c. |
| Fixed whitespace handling |
| Added a call to png_set_packing() |
| Initialize dimension values so if sscanf fails at least we have known |
| invalid values. |
| Attempt to detect configuration issues with png-fix-too-far-back, which |
| requires both the correct libpng and the correct zlib to function |
| correctly. |
| Check ZLIB_VERNUM for mismatches, enclose #error in quotes |
| Added information in the documentation about problems with and fixes for |
| the bad CRC and bad iTXt chunk situations. |
| |
| Version 1.6.3beta06 [May 12, 2013] |
| Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and |
| WRITE_PACK supported (writes error message that it can't read P1 or |
| Improved png-fix-too-far-back usage message, added --suffix option. |
| Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the |
| right zlib header files. |
| Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile |
