Changes since the last public release (1.6.17):
Version 1.6.18beta01 [April 1, 2015]
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]).
Version 1.6.18beta02 [April 26, 2015]
Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler
(Bug report by Viktor Szaka'ts).
Version 1.6.18beta03 [May 6, 2015]
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).
Version 1.6.18beta04 [May 7, 2015]
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.
