Changes since the last public release (1.2.18):
@@ -138,6 +138,34 @@ version 1.2.19beta24 [July 14, 2007]
Added PNG_NO_READ_FILTER, PNG_NO_WRITE_FILTER, PNG_NO_WARNING macros.
Added contrib/pngminim to demonstrate building minimal encoder and decoder
version 1.2.19beta25 [July 15, 2007]
Removed the new PNG_NO_READ_FILTER macro since it would make the library
unable to read valid PNG files, and filtering is at the heart of the
PNG format.
version 1.2.19beta26 [July 16, 2007]
Changed "png_free(str)" to "png_free(png_ptr,str)" in pngrutil.c WinCE
code (Yves Piguet). This bug was introduced in libpng-1.2.14.
Updated scripts/CMakeLists.txt
Relocated a misplaced #endif in pnggccrd.c
version 1.2.19beta27 [July 17, 2007]
Fixed incorrect stride and number of bytes copied (was 4 instead of
6 bytes) in the cleanup loop of pnggccrd.c and pngvcrd.c for handling
the end of 48-bit interlaced rows (Glenn R-P).
version 1.2.19beta28 [July 19, 2007]
Removed requirement for gcc-4.1 or better to use PNG_HAVE_MMX_FILTER_ROW
on x86_64 platforms
Added png_warning() in pngrutil.c for short iCCP, iTXt, sPLT, or zTXT chunks.
Revised pngtest.c so warnings are displayed regardless of PNG_NO_STDIO.
version 1.2.19beta29 [July 20, 2007]
Fix typo in pnggccrd.c (%%eax should be %%ax in secondloop48)
version 1.2.19beta30 [July 26, 2007]

4. June 28, 2007: Pnggccrd.c has been reported to be unreliable on
several 64-bit platforms running gcc-3.4.6. It appears to build
properly, but it does not always read files correctly, leading to
corrupted output or to a crash of the application.
STATUS: Appears to be a bug in the 64-bit version of gcc-3.4.6.
Workarounds are to use -DPNG_NO_MMX_CODE or to upgrade gcc to a
newer version.
