-Changes since the last public release (1.5.2):
-
-  More -Wshadow fixes for older gcc compilers.  Older gcc versions apparently
-    check formal parameters names in function declarations (as well as
-    definitions) to see if they match a name in the global namespace.
-  Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the
-    old VisualC++ preprocessor.
-  Turned on interlace handling in png_read_png().
-  Fixed gcc pendantic warnings.
-  Handle longjmp in Cygwin.
-  Fixed png_get_current_row_number() in the interlaced case.
-  Cleaned up ALPHA flags and transformations.
-  Implemented expansion to 16 bits.
-  Fixed mistake in the descriptions of user read_transform and write_transform
-    function prototypes in the manual.  The row_info struct is png_row_infop.
-  Corrected png_get_current_row_number documentation
-  Fixed the read/write row callback documentation.
-    This documents the current behavior, where the callback is called after
-    every row with information pertaining to the next row.
-  Fixed scripts/makefile.vcwin32
-  Updated contrib/pngsuite/README to add the word "modify".
-  Define PNG_ALLOCATED and other attributes to blank when _MSC_VER<1300.
-  ifdef out mask arrays in pngread.c when interlacing is not supported.
-  Added a hint to try CPP=/bin/cpp if "cpp -E" fails in scripts/pnglibconf.mak
-    and in contrib/pngminim/*/makefile, eg., on SunOS 5.10, and removed "strip"
-    from the makefiles.
-  Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail
-    to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill)
-  Don't include standard header files in png.h while building the symbol table,
-    to avoid cpp failure on SunOS (introduced PNG_BUILDING_SYMBOL_TABLE macro).

+Changes since the last public release (1.5.8):
+
+  Rebuilt configure scripts in the tar distributions.
+  Removed two unused definitions from scripts/pnglibconf.h.prebuilt
+  Removed some unused arrays (with #ifdef) from png_read_push_finish_row().
+  Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h
+  Fixed CVE-2011-3026 buffer overrun bug.  Deal more correctly with the test
+    on iCCP chunk length. Also removed spurious casts that may hide problems
+    on 16-bit systems.
