| Changes since the last public release (1.5.18): |
| Moved redefines of png_error(), png_warning(), png_chunk_error(), |
| and png_chunk_warning() from pngpriv.h to png.h to make them visible |
| to libpng-calling applications. |
| Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS |
| and PNG_USR_CONFIG -> PNG_USER_CONFIG). |
| Use "if (value != 0)" instead of "if (value)" consistently. |
| Moved configuration information from the manual to the INSTALL file. |
| Removed #if/#else/#endif from inside two pow() calls in pngvalid.c because |
| they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3 |
| when using its "__builtin_pow()" function. |
| Silence 'unused parameter' build warnings (Cosmin). |
| $(CP) is now used alongside $(RM_F). Also, use 'copy' instead |
| of 'cp' where applicable, and applied other minor makefile changes. |
| Don't warn about invalid dimensions exceeding user limits. |
| Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that interferes |
| with "blocky" expansion of sub-8-bit interlaced PNG files (Eric Huss). |
| Removed scripts/makefile.elf. It has not worked since libpng-1.5.0beta14 |
| due to elimination of the PNG_FUNCTION_EXPORT and PNG_DATA_EXPORT |
| definitions from pngconf.h. |
| Allow an easy replacement of the default pre-built configuration |
| header with a custom header, via the make PNGLIBCONF_H_PREBUILT |
| macro. |
| Added opinion that the ECCN (Export Control Classification Number) for |
| libpng is EAR99 to the README file. |
| Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu |
| Added PNG_UNUSED(png_ptr) and PNG_UNUSED(val) in png_longjmp() (Cosmin). |
