-Changes since the last public release (1.6.12):
-
- Quieted -Wsign-compare and -Wclobber compiler warnings in
- contrib/pngminus/*.c
- Added "(void) png_ptr;" where needed in contrib/gregbook to quiet
- compiler complaints about unused pointers.
- Split a long output string in contrib/gregbook/rpng2-x.c.
- Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa,
- Needed for write-only support (John Bowler).
- Changed "if defined(__ARM_NEON__)" to
- "if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu).
- Fixed clang no-warning builds: png_digit was defined but never used.
- Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32
- (bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11.
- Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and
- makefile.tc3 similarly.
- 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.
- Ensure that CMakeLists.txt makes the target "lib" directory before making
- symbolic link into it (SourceForge bug report #226 by Rolf Timmermans).
- Added opinion that the ECCN (Export Control Classification Number) for
- libpng is EAR99 to the README file.
- Eliminated use of "$<" in makefile explicit rules, when copying
- $PNGLIBCONF_H_PREBUILT. This does not work on some versions of make;
- bug introduced in libpng version 1.6.11.
- Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu
