-Changes since the last public release (1.6.20):
-
- Fixed syntax "$(command)" in tests/pngstest that some shells other than
- bash could not parse (Bug report by Nelson Beebe). Use `command` instead.
- Moved png_check_keyword() from pngwutil.c to pngset.c
- Removed LE/BE dependencies in pngvalid, to 'fix' the current problem
- in the BigEndian tests by not testing it, making the BE code the same
- as the LE version.
- Fixes to pngvalid for various reduced build configurations (eliminate unused
- statics) and a fix for the case in rgb_to_gray when the digitize option
- reduces graylo to 0, producing a large error.
- Widened the 'limit' check on the internally calculated error limits in
- the 'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error
- checks) and changed the check to only operate in non-release builds
- (base build type not RC or RELEASE.)
- Fixed undefined behavior in pngvalid.c, undefined because
- (png_byte) << shift is undefined if it changes the signed bit
- (because png_byte is promoted to int). The libpng exported functions
- png_get_uint_32 and png_get_uint_16 handle this. (Bug reported by
- David Drysdale as a result of reports from UBSAN in clang 3.8).
- This changes pngvalid to use BE random numbers; this used to produce
- errors but these should not be fixed as a result of the previous changes.
- In projects/vstudio, combined readme.txt and WARNING into README.txt
- Relocated assert() in contrib/tools/pngfix.c, bug found by American
- Fuzzy Lop, reported by Brian Carpenter.
- Marked 'limit' UNUSED in transform_range_check(). This only affects
- release builds.
- Worked around a false-positive Coverity issue in pngvalid.c.

+
+Changes since the last public release (1.6.21):
+ Changed PNG_USE_MKSTEMP to __COVERITY__ to select alternate
+ "tmpfile()" implementation in contrib/libtests/pngstest.c
+ Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io()
+ if there is no stdio.h support.
+ Added a png_image_write_to_memory() API and a number of assist macros
+ to allow an application that uses the simplified API write to bypass
+ stdio and write directly to memory.
+ Added some warnings (png.h) and some check code to detect *possible*
+ overflow in the ROW_STRIDE and simplified image SIZE macros. This
+ disallows image width/height/format that *might* overflow. This is
+ a quiet API change that limits in-memory image size (uncompressed) to
+ less than 4GByte and image row size (stride) to less than 2GByte.
+ Revised workaround for false-positive Coverity issue in pngvalid.c.
+ Only use exit(77) in configure builds.
+ Updated CMakeLists.txt, added supporting scripts/gen*.cmake.in
+ and test.cmake.in (Roger Leigh).
+ Relaxed limit checks on gamma values in pngrtran.c. As suggested in
+ the comments gamma values outside the range currently permitted
+ by png_set_alpha_mode are useful for HDR data encoding. These values
+ are already permitted by png_set_gamma so it is reasonable caution to
+ extend the png_set_alpha_mode range as HDR imaging systems are starting
+ to emerge.
+ Added a common-law trademark notice and export control information
+ to the LICENSE file, png.h, and the man page.
+ Restored "& 0xff" in png_save_uint_16() and png_save_uint_32() that
+ were accidentally removed from libpng-1.6.17.
+ Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h
+ (Robert C. Seacord).
+ Removed dubious "#if INT_MAX" test from png.h that was added to
+ libpng-1.6.19 (John Bowler).
+ Add ${INCLUDES} in scripts/genout.cmake.in (Bug report by Nixon Kwok).
+ Updated LICENSE to say files in the contrib directory are not
+ necessarily under the libpng license, and that some makefiles have
+ other copyright owners.
+ Added INTEL-SSE2 support (Mike Klein and Matt Sarett, Google, Inc.).
+ Made contrib/libtests/timepng more robust. The code no longer gives
+ up/fails on invalid PNG data, it just skips it (with error messages).
+ The code no longer fails on PNG files with data beyond IEND. Options
+ exist to use png_read_png (reading the whole image, not by row) and, in
+ that case, to apply any of the supported transforms. This makes for
+ more realistic testing; the decoded data actually gets used in a
+ meaningful fashion (John Bowler).
+ Fixed some misleading indentation (Krishnaraj Bhat).
+ Force GCC compilation to C89 if needed (Dagobert Michelsen).
+ SSE filter speed improvements for bpp=3:
+ memcpy-free implementations of load3() / store3().
+ call load3() only when needed at the end of a scanline.
+ Added PNG_FAST_FILTERS macro (defined as
+ PNG_FILTER_NONE|PNG_FILTER_SUB|PNG_FILTER_UP).
+ Various fixes for contrib/libtests/timepng.c
+ Fixed typo (missing underscore) in #define PNG_READ_16_TO_8_SUPPORTED
+ (Bug report by Y.Ohashik).
+ Quieted two Coverity issues in contrib/libtests/timepng.c.
+ Fixed issues with scripts/genout.cmake.in (David Capello, Nixon Kwok):
+ Added support to use multiple directories in ZLIBINCDIR variable,
+ Fixed CMAKE_C_FLAGS with multiple values when genout is compiled on MSVC,
+ Fixed pnglibconf.c compilation on OS X including the sysroot path.
+ Check for CLOCK_PROCESS_CPUTIME_ID when building /contrib/libtests/timepng.
+ Check for the presence of clock_gettime() in configure.ac and Makefile.am.
