| Changes since the last public release (1.6.7): |
| Changed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpread.c to |
| #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED to be consistent with |
| what is in pngpriv.h. |
| Moved prototype for png_handle_unknown() in pngpriv.h outside of |
| the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block. |
| Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile |
| Conditionally compile some unused functions reported by -Wall in |
| pngminim. |
| Fixed 'minimal' builds. Various obviously useful minimal configurations |
| don't build because of missing contrib/libtests test programs and |
| overly complex dependencies in scripts/pnglibconf.dfa. This change |
| adds contrib/conftest/*.dfa files that can be used in automatic build |
| scripts to ensure that these configurations continue to build. |
| Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. |
| Fixed pngvalid 'fail' function declaration on the Intel C Compiler. |
| This reverts to the previous 'static' implementation and works round |
| the 'unused static function' warning by using PNG_UNUSED(). |
| Removed or marked PNG_UNUSED some harmless "dead assignments" reported |
| by clang scan-build. |
| Changed tabs to 3 spaces in png_debug macros and changed '"%s"m' |
| to '"%s" m' to improve portability among compilers. |
| Changed png_free_default() to free() in pngtest.c |
| Tidied up pngfix inits and fixed pngtest no-write builds. |
| Handle zero-length PLTE chunk or NULL palette with png_error() |
| instead of png_chunk_report(), which by default issues a warning |
| rather than an error, leading to later reading from a NULL pointer |
| (png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954 |
| and VU#650142. |
