-Libpng 1.2.7 - September 12, 2004
+Libpng 1.2.16 - January 31, 2007
 
 This is a public release of libpng, intended for use in production codes.
 
-Changes since the last public release (1.2.6):
-
-  Revised pngtest so memory allocation testing is only done when PNG_DEBUG==1.
-  Removed unused pngasmrd.h file.
-  Removed references to uu.net for archived files.  Added references to
-    PNG Spec (second edition) and the PNG ISO/IEC Standard.
-  Added "test-dd" target in 15 makefiles, to run pngtest in DESTDIR.
-  Fixed bug with "optimized window size" in the IDAT datastream, that
-    causes libpng to write PNG files with incorrect zlib header bytes.
-  Fixed bug with sCAL chunk and big-endian machines (David Munro).
-  Undid new code added in 1.2.6 to update the color_type in
-    png_set_filler().
-  Added png_set_add_alpha() that updates color type.
-  Revised png_set_strip_filler() to not remove alpha if color_type has alpha.
-  Added makefile.hp64
-  Changed projects/msvc/png32ms.def to scripts/png32ms.def in makefile.cygwin
