+Libpng 1.5.13 - September 27, 2012
+
+This is a public release of libpng, intended for use in production codes.
+
+Files available for download:
+
+Source files with LF line endings (for Unix/Linux) and with a
+"configure" script
+
+ libpng-1.5.13.tar.xz (LZMA-compressed, recommended)
+ libpng-1.5.13.tar.gz
+ libpng-1.5.13.tar.bz2
+
+Source files with CRLF line endings (for Windows), without the
+"configure" script
+
+ lpng1513.7z (LZMA-compressed, recommended)
+ lpng1513.zip
+
+Other information:
+
+ libpng-1.5.13-README.txt
+ libpng-1.5.13-LICENSE.txt
+
+Changes since the last public release (1.5.12):
+ Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
+ Removed references to png_zalloc() and png_zfree() from the manual.
+ Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
+ lone semicolons (patch ported from libpng-1.6.0beta11).
+ Corrected handling of the image array and the row_pointers array in example.c
+ When png_set_filler is used to strip a filler channel during write, the
+ code prior to 1.5 would ignore the case where the output required an
+ alpha channel or when the output was a palettized PNG. In libpng-1.5 the
+ ignorance was lost and libpng proceeded to strip the channel resulting
+ in a bad (potential memory overwrite) failure later. This reverts
+ the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
+ expected to issue an error on the erroneous png_set_filler call.
+ Use png_memset() consistently (pngmem.c contained some bare "memset" calls).
