Libpng 1.7.0beta65 - September 15, 2015
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.

Authors.
Version 1.7.0beta65 [August 3, 2015]
Version 1.7.0beta65 [September 15, 2015]
Use nanosleep() instead of usleep() in contrib/gregbook/rpng2-x.c
because usleep() is deprecated (port from libpng16).
Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c
@ -860,6 +860,7 @@ Version 1.7.0beta65 [August 3, 2015]
Moved config.h.in~ from the "libpng_autotools_files" list to the
"libpng_autotools_extra" list in autogen.sh because it was causing a
false positive for missing files (bug report by Robert C. Seacord).
Fixed some bad links in the man page.

"libpng_autotools_extra" list in autogen.sh because it was causing a
false positive for missing files (bug report by Robert C. Seacord).
Fixed some bad links in the man page.
Renamed the arm subdirectory to contrib/neon.
Made minor fixes to the test scripts:
pngimage: add --list-combos pngunknown: add --strict to catch warnings
pngvalid-standard: remove the spurious --progressive read (compare with
pngvalid-progressive-standard!) (John Bowler).
Implemented a new chunk parse implementation that can be shared. It
is currently shared by the progressive reader and the sequential one
(but not yet by the writer) (John Bowler).
Implemented shared transform handling that is used throughout (John Bowler).
