-Changes since the last public release (1.5.12):
- Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
- Removed references to png_zalloc() and png_zfree() from the manual.
- Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
- lone semicolons (patch ported from libpng-1.6.0beta11).
- Corrected handling of the image array and the row_pointers array in example.c
- When png_set_filler is used to strip a filler channel during write, the
- code prior to 1.5 would ignore the case where the output required an
- alpha channel or when the output was a palettized PNG. In libpng-1.5 the
- ignorance was lost and libpng proceeded to strip the channel resulting
- in a bad (potential memory overwrite) failure later. This reverts
- the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
- expected to issue an error on the erroneous png_set_filler call.
- Use png_memset() consistently (pngmem.c contained some bare "memset" calls).
+Changes since the last public release (1.5.13):
+ Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
+ Warn about the incorrect runtime library setting for VS2010 debug DLL builds.
+ Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
+ pngrtran.c (Domani Hannes).
+ Check for png_ptr==NULL earlier in png_zalloc().
+ Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS().
+ Rearranged building of ARM NEON optimizations. The ARM specific code is
+ split out entirely to the arm subdirectory and changes to configure.ac and
+ Makefile.am to add new stuff are reduced. Now material code changes,
+ although for build test purposes, --enable-arm-neon now builds on non-ARM
+ systems.
+ Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.12.5.
+ Fixed cases of unquoted DESTDIR in Makefile.am
+ Fixed a minor bug in types to malloc and major bug in handling compressed
+ iTXt. Compressed iTXt could not be handled.
+ Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
+ Disassembled the version number in scripts/options.awk (necessary for
+ building on SunOs).
+ Fixed Windows build issues, enabled ARM compilation. Various warnings issued
+ by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
+ GCCs.) ARM support is enabled by default in zlib.props (unsupported by
+ Microsoft) and ARM compilation is made possible by deleting the check for
+ x86. The test programs cannot be run because they are not signed.
+ Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
+ Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h])
+ in configure.ac
+ De-configured build fixes to make a range of deconfiguration options (such
+ as switching off read or write support) work in more cases. Also upgraded
+ pngtest and pngvalid to the libpng 1.6 versions (with some modifications)
+ which provide more extensive testing. Replaced pngtest.png because pngtest
+ writes the ancillary chunks in a different order.
+ Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
+ (Bug report from yuris).
+ Revised test for validity of "num_unknowns" to eliminate compiler warnings.
+ Check the validity of the "nentries" parameter of png_set_sPLT() and the
+ "num_text" parameter of png_set_text_2().

+Libpng 1.5 erroneously uses /MD when building debug DLL versions of libpng.
+It should use /MDd - you can change this under properties\C/C++\Code
+Generation\Runtime Library if you need to use the debug runtime for debug
+builds. This will be changed in libpng 1.6 but is currently retained for
+compatibility with older libpng 1.5 releases.
+
+The runtime library settings for each build are as follows:
+
+ Release Debug
+DLL /MD /MD
+Library /MT /MTd
+
+The Visual Studio 2010 defaults for a Win32 DLL or Static Library project are
+as follows:
+
+ Release Debug
+DLL /MD /MDd
+Static Library /MD /MDd
+
+Notice that by default static library builds use the DLL runtime, not the
+static library runtime.
