| Changes since the last public release (1.5.19): |
| Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa |
| Only mark text chunks as written after successfully writing them. |
| Avoid out-of-bounds memory access in png_user_version_check(). |
| Simplified and future-proofed png_user_version_check(). |
| Quieted three "comparison is always false due to limited range" compiler |
| warnings in pngset.c |
| The macros passed in the command line to Borland make were ignored if |
| similarly-named macros were already defined in makefiles. This behavior |
| is different from POSIX make and other make programs. Surround the |
| macro definitions with ifndef guards (Cosmin). |
| Use memcpy instead of CopyMemory in the definition of png_memcpy. |
| The Borland C++ build breaks otherwise (Cosmin). |
| Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32 |
| Removed the obsolete $ARCH variable from scripts/makefile.darwin. |
