+
+Changes since the last public release (1.6.17):
+ Removed PNG_SET_CHUNK_[CACHE|MALLOC]_LIMIT_SUPPORTED macros. They
+ have been combined with PNG_SET_USER_LIMITS_SUPPORTED (resolves
+ bug report by Andrew Church).
+ Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. This
+ fixes some arithmetic errors that caused some tests to fail on
+ some 32-bit platforms (Bug reports by Peter Breitenlohner [i686]
+ and Petr Gajdos [i586]).
+ Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler
+ (Bug report by Viktor Szaka'ts).
+ Replaced "unexpected" with an integer (0xabadca11) in pngset.c
+ where a long was expected, to avoid a compiler warning when PNG_DEBUG > 1.
+ Added contrib/examples/simpleover.c, to demonstrate how to handle
+ alpha compositing of multiple images, using the "simplified API"
+ and an example PNG generation tool, contrib/examples/genpng.c
+ (John Bowler).
+ PNG_RELEASE_BUILD replaces tests where the code depended on the build base
+ type and can be defined on the command line, allowing testing in beta
+ builds (John Bowler).
+ Avoid Coverity issue 80858 (REVERSE NULL) in pngtest.c
+ Avoid a harmless potential integer overflow in png_XYZ_from_xy() (Bug
+ report from Christopher Ferris).
+ Backport filter selection code from libpng-1.7.0beta51, to combine
+ sub_row, up_row, avg_row, and paeth_row into try_row and tst_row.
+ Changed png_voidcast(), etc., to voidcast(), etc., in contrib/tools/pngfix.c
+ to avoid confusion with the libpng private macros.
+ Fixed old cut&paste bug in the weighted filter selection code in
+ pngwutil.c, introduced in libpng-0.95, March 1997.
+ Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the
+ compiled library size. It never worked properly and as far as we can
+ tell, no one uses it. The png_set_filter_heuristics() and
+ png_set_filter_heuristics_fixed() APIs are retained but deprecated
+ and do nothing.
+ Quieted some Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c,
+ pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt
+ would only work with iTXt chunks with length 255 or less.
+ Removed non-working progressive reader 'skip' function. This
+ function has apparently never been used. It was implemented
+ to support back-door modification of png_struct in libpng-1.4.x
+ but (because it does nothing and cannot do anything) was apparently
+ never tested (John Bowler).
+ Fixed cexcept.h in which GCC 5 now reports that one of the auto
+ variables in the Try macro needs to be volatile to prevent value
+ being lost over the setjmp (John Bowler).
+ Added #ifdef's to contrib/examples programs so people don't try
+ to compile them without the minimum required support enabled
+ (suggested by Flavio Medeiros).
+ Eliminated the final two Coverity defects (insecure temporary file
+ handling in contrib/libtests/pngstest.c; possible overflow of
+ unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure"
+ file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will
+ be used.
+ Removed some unused WEIGHTED_FILTER macros from pngstruct.h
+ Replaced arbitrary use of 'extern' with #define PNG_LINKAGE_*. To
+ preserve API compatibility, the new defines all default to "extern"
+ (requested by Jan Nijtmans).
+ Belatedly added Mans Rullgard and James Yu to the list of Contributing
+ Authors.
