3095 Changes are trivial rearrangements of code. -Wconversion is not possible
3097 smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
3107 Included documentation of changes in 1.5.0 from 1.4.x in libpng-manual.txt

3239 The type was self-evidently incorrect but only causes problems on 64-bit
3255 More -Wshadow fixes for older gcc compilers. Older gcc versions apparently
3286 Added a hint to try CPP=/bin/cpp if "cpp -E" fails in scripts/pnglibconf.mak
3289 Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail
3300 Re-initialize the zlib compressor before compressing non-IDAT chunks.
3302 set parameters for zlib compression of non-IDAT chunks.

3371 Removed the -D_ALL_SOURCE from definitions for AIX in CMakeLists.txt
3378 for Macs - it's not a good idea to embed this in the ABI!
3382 Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
3386 Improved "pngvalid --speed" to exclude more of pngvalid from the time.
3387 Documented png_set_alpha_mode(), other changes in libpng.3/libpng-manual.txt
3390 sRGB/Rec 709 values are still used. This introduced a divide-by-zero
3405 back where it was. The change doesn't work because it requires 16-bit
3406 gamma tables when the code only generates 8-bit ones. This fails
3408 the tests back leaves the old, inaccurate, 8-bit gamma calculations, but
3416 treats it as an 8-bit color because of where png_do_expand_16 is in the

3431 Fixed png_handle_sCAL which is broken in 1.5. This fixes CVE 2011-2692.
3438 Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
3460 to be confusing; therefore we bump the version to libpng-1.5.4beta01

3568 based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT
3569 VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected.
3574 the 8-bit non-gamma-corrected case (where consistency seems more important
3576 8-bit case because 8-bit linear arithmetic is used.
3585 Fixed 64-bit compilation errors (gcc). The errors fixed relate
3586 to conditions where types that are 32 bits in the GCC 32-bit
3587 world (uLong and png_size_t) become 64 bits in the 64-bit
3591 Constant changes for 64-bit compatibility (removal of L suffixes). The
3592 16-bit cases still use "L" as we don't have a 16-bit test system.
3601 Fixed some 64-bit type conversion warnings in pngrtran.c
3620 Revised test-pngtest.sh to report FAIL when pngtest fails.
3621 Added "--strict" option to pngtest, to report FAIL when the failure is
3624 CMakeLists.txt that is no longer useful in libpng-1.5.
3627 Fixed typo in Makefile.in and Makefile.am ("-M Wl" should be "-M -Wl")."
3634 Align png_struct::row_buf - previously it was always unaligned, caused by
3639 percentage for 16-bit and 32-bit pixels in the typical case where the
3655 it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
3660 Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row
3667 Added LSR() macro to defend against buggy compilers that evaluate non-taken
3668 code branches and complain about out-of-range shifts.
3674 enables that fix for all compilers when using compile-time constants.
3683 Added support for ARM processor, when decoding all PNG up-filtered rows

3703 be non-NULL. The cast of the profile length potentially truncated the
3704 value unnecessarily on a 16-bit int system, so the cast of the (byte)
3705 compression type to (int) is specified by ANSI-C anyway.
3718 modified tables reduce the number of 16-bit values that
3719 convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used
3720 to generate the tables is now in a contrib/sRGBtables sub-directory.
3724 Added run-time detection of NEON support.
3727 Multiple transform bug fixes plus a work-round for double gamma correction.
3729 at once - if this is tried typically the results is double gamma
3732 libpng transform code. This check-in also contains fixes to various bugs
3741 Added --noexecstack to assembler file compilation. GCC does not set
3744 work-around is to set it by default in the flags for $(CCAS)
3747 not initialized); this turns on const-ness only for compilers where
3751 Since the gcc driver does not recognize the --noexecstack flag, we must
3752 use the -Wa prefix to have it passed through to the assembler.
3754 Added files that were omitted from the libpng-1.5.7beta03 zip distribution.
3759 (Frank Busse). Note: This prevented CVE-2015-7981 from affecting
3760 libpng-1.5.7 and later.
3769 Rebuilt Makefile.in, configure, etc., with autoconf-2.68
3779 as in libpng-1.5.4.
3791 Removed machine-generated configure files from the GIT repository (they will
3793 earlier GIT branches).
3794 Restored the new 'simplified' API, which was started in libpng-1.5.7beta02
3795 but later deleted from libpng-1.5.7beta05.
3797 Added ANSI-C (C90) headers and require them, and take advantage of the
3800 With this change the required ANSI-C header files are assumed to exist: the

3846 Regenerated configure scripts with automake-1.11.2
3863 (all those cases where the thing being copied is a non-array C L-value).
3865 Removed the reference to the non-exported function png_memcpy() from
3867 Fixed the Visual C 64-bit build - it requires jmp_buf to be aligned, but
3875 (CVE-2011-3464, bug introduced in libpng-1.5.3beta05).
3882 Added color-map support to simplified API. This is an initial version for

3893 (replaced with 3-character indentation). Obsolete macros identified by
3895 the pre-req hasn't been changed. --enable-werror checks for support
3896 for -Werror (or the given argument) in the compiler. This mimics the
3897 gcc configure option by allowing -Werror to be turned on safely; without
3900 Rewrote autogen.sh to run autoreconf instead of running tools one-by-one.
3908 Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
3915 Divide test-pngstest.sh into separate pngstest runs for basic and
3918 Added color-tests, silent-rules (Not yet implemented in Makefile.am) and
3921 the background parameter of png_image_finish_read. The --background
3936 Reverted the prebuilt configure files to libpng-1.6.0beta05 condition.
3939 Added Z_SOLO for zlib-1.2.6+ and correct pngstest tests

4035 variable. GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit)
4036 to an (int) (signed 32-bit). MSVC, however, warns about using the
4037 unary '-' operator on an unsigned value (even though it is well defined
4038 by ANSI-C to be ~x+1). The padding calculation was changed to use a
4039 different method. Removed the tests on png_ptr->pass.
4044 code now claims and releases png_ptr->zstream, like the write code.

4071 Fixed an off-by-one error in the palette index checking function.
4072 Fixed a compiler warning under Cygwin (Windows-7, 32-bit system)
4075 This avoids compiler warnings when -Wwrite-strings is enabled.

4104 benign errors; also added --strict to pngstest - not enabled
4107 This allows the --strict option to pass in the pngstest checks
4111 Added checksum-icc.c to contrib/tools
4117 CVE-2011-3048, also known as CVE-2012-3425).
4127 Added -lssp_nonshared in a comment in scripts/makefile.freebsd
4131 Removed need for -Wno-cast-align with clang. clang correctly warns on
4132 alignment increasing pointer casts when -Wcast-align is passed. This
4165 Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386.
4178 Re-eliminated the use of strcpy() in pngtest.c. An unnecessary use of

4350 Rebuilt configure with autoconf-2.69 (inadvertently not done in beta33)
4351 Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
4359 (CVE-2013-7353). Added overflow detection in png_set_sPLT() and
