-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.
