Changes since the last public release (1.6.30):
|
|
|
|
Version 1.6.31beta01 [July 5, 2017]
|
|
Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it;
|
|
bug report by Michael Felt).
|
|
Revised pngpriv.h to work around failure to compile arm/filter_neon.S
|
|
("typedef" directive is unrecognized by the assembler). The problem
|
|
was introduced in libpng-1.6.30beta01.
|
|
Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx).
|
|
Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
|
|
|
|
Version 1.6.31beta02 [July 8, 2017]
|
|
Added instructions for disabling hardware optimizations in INSTALL.
|
|
Added "--enable-hardware-optimizations" configuration flag to enable
|
|
or disable all hardware optimizations with one flag.
|
|
|
|
Version 1.6.31beta03 [July 9, 2017]
|
|
Updated CMakeLists.txt to add INTEL_SSE and MIPS_MSA platforms.
|
|
Changed "int" to "png_size_t" in intel/filter_sse2.c to prevent
|
|
possible integer overflow (Bug report by John Bowler).
|
|
Quieted "declaration after statement" warnings in intel/filter_sse2.c.
|
|
Added scripts/makefile-linux-opt, which has hardware optimizations enabled.
|
|
|
|
Version 1.6.31beta04 [July 11, 2017]
|
|
Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
|
|
integers appear on both sides of a compare. Worked around the others by
|
|
forcing the strict-overflow setting in the relevant functions to a level
|
|
where they are not reported (John Bowler).
|
|
Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
|
|
the space.
|
|
Worked around some C-style casts from (void*) because g++ 5.4.0 objects
|
|
to them.
|
|
Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
|
|
overflow' check that is on by default with -Wall -Wextra.
|
|
|
|
Version 1.6.31beta05 [July 13, 2017]
|
|
Added eXIf chunk support.
|
|
|
|
Version 1.6.31beta06 [July 17, 2017]
|
|
Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
|
|
tags) to pngtest.png.
|
|
|
|
Version 1.6.31beta07 [July 18, 2017]
|
|
Revised the eXIf chunk in pngtest.png to fix "Bad IFD1 Directory" warning.
|
|
|
|
Version 1.6.31rc01 [July 19, 2017]
|
|
No changes.
|
|
|
|
Version 1.6.31rc02 [July 25, 2017]
|
|
Fixed typo in example.c (png_free_image should be png_image_free) (Bug
|
|
report by John Smith)
