25 Changes since the last public release (1.6.12):
27 Quieted -Wsign-compare and -Wclobber compiler warnings in
29 Added "(void) png_ptr;" where needed in contrib/gregbook to quiet
30 compiler complaints about unused pointers.
31 Split a long output string in contrib/gregbook/rpng2-x.c.
32 Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa,
33 Needed for write-only support (John Bowler).
34 Changed "if defined(__ARM_NEON__)" to
35 "if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu).
36 Fixed clang no-warning builds: png_digit was defined but never used.
37 Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32
38 (bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11.
39 Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and
40 makefile.tc3 similarly.
41 Removed scripts/makefile.elf. It has not worked since libpng-1.5.0beta14
42 due to elimination of the PNG_FUNCTION_EXPORT and PNG_DATA_EXPORT
43 definitions from pngconf.h.
44 Ensure that CMakeLists.txt makes the target "lib" directory before making
45 symbolic link into it (SourceForge bug report #226 by Rolf Timmermans).
46 Added opinion that the ECCN (Export Control Classification Number) for
47 libpng is EAR99 to the README file.
48 Eliminated use of "$<" in makefile explicit rules, when copying
49 $PNGLIBCONF_H_PREBUILT. This does not work on some versions of make;
50 bug introduced in libpng version 1.6.11.
51 Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu
