| 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 1.6.3beta04 [May 6, 2013] |
| Calculate our own zlib windowBits when decoding rather than trusting the |
| CMF bytes in the PNG datastream. |
| |
| Version 1.6.3beta05 [May 9, 2013] |
| Choose to use windowBits==15 or the zlib header setting via the |
| benign-errors setting. If benign errors are allowed, then ignore |
| the windowBits setting in the zlib header. |
| Zlib-1.2.8 and earlier don't allow us to decrease the windowBits, so |
| undid the improvement in beta04. |
| Added an option to force maximum window size for inflating. For inflate, |
| reverted previous fixes. |
| Added fixitxt and pngdeflate to the built programs and removed warnings |
| from the source code and timepng that are revealed as a result. Fixed |
| fixitxt when the chunk length is more than 65535 (untested, no test case). |
| Detect wrong libpng versions linked to pngdeflate, 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 pngdeflate, which requires |
| both the correct libpng and the correct zlib to function correctly. |
| Check ZLIB_VERNUM for mismatches, enclose #error in quotes |
| Renamed contrib/tools/fixitxt to contrib/tools/png-fix-itxt. |
| Renamed contrib/tools/pnginflate to contrib/tools/png-fix-too-far-back. |
| Added information in the documentation about problems with and fixes for |
| the bad CRC and bad iTXt chunk situations. |
