Gnupg/*.asc (PGP armored detached signatures)
Changes since the last public release (1.6.7):
Changed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpread.c to
#ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED to be consistent with
what is in pngpriv.h.
Moved prototype for png_handle_unknown() in pngpriv.h outside of
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
Conditionally compile some unused functions reported by -Wall in
pngminim.
Fixed 'minimal' builds. Various obviously useful minimal configurations
don't build because of missing contrib/libtests test programs and
overly complex dependencies in scripts/pnglibconf.dfa. This change
adds contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.
Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.
Fixed pngvalid 'fail' function declaration on the Intel C Compiler.
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().
Removed or marked PNG_UNUSED some harmless "dead assignments" reported
by clang scan-build.
Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
to '"%s" m' to improve portability among compilers.
Changed png_free_default() to free() in pngtest.c
Tidied up pngfix inits and fixed pngtest no-write builds.
Handle zero-length PLTE chunk or NULL palette with png_error()
instead of png_chunk_report(), which by default issues a warning
rather than an error, leading to later reading from a NULL pointer
(png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954
and VU#650142.
Changes since the last public release (1.6.8):
Bookkeeping: Moved functions around (no changes). Moved transform
function definitions before the place where they are called so that
they can be masde static. Move the intrapixel functions and the
grayscale palette builder out of the png?tran.c files. The latter
isn't a transform function and is no longer used internally, and the
former MNG specific functions are better placed in pngread/pngwrite.c
Made transform implementation functions static. This makes the internal
functions called by png_do_{read|write}_transformations static. On an
x86-64 DLL build (Gentoo Linux) this reduces the size of the text
segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
maintenance by removing the declarations from pngpriv.h and allowing
easier changes to the internal interfaces.
Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69
in the tar distributions.
Added checks for libpng 1.5 to pngvalid.c. This supports the use of
this version of pngvalid in libpng 1.5
Merged with pngvalid.c from libpng-1.7 changes to create a single
pngvalid.c
Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner).
Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0
Merged libpng-1.7.0 changes to make no-interlace configurations work
with test programs.
Revised pngvalid.c to support libpng 1.5, which does not support the
PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
pngvalid.c
Allow unversioned links created on install to be disabled in configure.
In configure builds 'make install' changes/adds links like png.h
and libpng.a to point to the newly installed, versioned, files (e.g.
libpng17/png.h and libpng17.a). Three new configure options and some
rearrangement of Makefile.am allow creation of these links to be disabled.
Removed potentially misleading warning from png_check_IHDR().
Updated scripts/makefile.* to use CPPFLAGS (Cosmin).
Added clang attribute support (Cosmin).
Quiet an uninitialized memory warning from VC2013 in png_get_png().
