-Changes since the last public release (1.6.23):
- Avoid potential overflow of the PNG_IMAGE_SIZE macro. This macro
- is not used within libpng, but is used in some of the examples.
- Correct filter heuristic overflow handling. This was broken when the
- write filter code was moved out-of-line; if there is a single filter and
- the heuristic sum overflows the calculation of the filtered line is not
- completed. In versions prior to 1.6 the code was duplicated in-line
- and the check not performed, so the filter operation completed; however,
- in the multi-filter case where the sum is performed the 'none' filter would
- be selected if all the sums overflowed, even if it wasn't in the filter
- list. The fix to the first problem is simply to provide PNG_SIZE_MAX as
- the current lmins sum value; this means the sum can never exceed it and
- overflows silently. A reasonable compiler that does choose to inline
- the code will simply eliminate the sum check.
- The fix to the second problem is to use high precision arithmetic (this is
- implemented in 1.7), however a simple safe fix here is to chose the lowest
- numbered filter in the list from png_set_filter (this only works if the
- first problem is also fixed) (John Bowler).
- Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois).
- Fixed the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application
- as a result of the application using an increased 'row_stride'; previously
- png_image_finish_read only checked for overflow on the base calculation of
- components. (I.e. it checked for overflow of a 32-bit number on the total
- number of pixel components in the output format, not the possibly padded row
- length and not the number of bytes, which for linear formats is twice the
- number of components.)
- MSVC does not like '-(unsigned)', so replaced it with 0U-(unsigned)
- MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), unless
- the conversion is explicitly invoked by a cast.
- Put the SKIP definition in the correct place. It needs to come after the
- png.h include (see all the other .c files in contrib/libtests) because it
- depends on PNG_LIBPNG_VER.
- Removed the three compile warning options from the individual project
- files into the zlib.props globals. It increases the warning level from 4
- to All and adds a list of the warnings that need to be turned off. This is
- semi-documentary; the intent is to tell libpng users which warnings have
- been examined and judged non-fixable at present. The warning about
- structure padding is fixable, but it would be a signficant change (moving
- structure members around).
- Optimized absolute value calculation in filter selection, similar to
- code in the PAETH decoder in pngrutil.c. Build with PNG_USE_ABS to
- use this.
- Added pngcp to the build together with a pngcp.dfa configuration test.
- Added high resolution timing to pngcp.
- Added "Common linking failures" section to INSTALL.
- Relocated misplaced #endif in png.c sRGB profile checking.
- Fixed two Coverity issues in pngcp.c.
- Avoid filter-selection heuristic sum calculations in cases where only one
- filter is a candidate for selection. This trades off code size (added
- private png_setup_*_row_only() functions) for speed.
- Fixed some indentation to comply with our coding style.
- Added contrib/tools/reindent.
- Eliminated unnecessary tests of boolean png_isaligned() vs 0.
- Conditionally compile SSE2 headers in contrib/intel/intel_sse.patch
- Conditionally compile png_decompress_chunk().
- Conditionally compile ARM_NEON headers in pngpriv.h
- Updated contrib/intel/intel_sse.patch
+Changes since the last public release (1.6.24):
+ Reject oversized iCCP profile immediately.
+ Cleaned up PNG_DEBUG compile of pngtest.c.
+ Conditionally compile png_inflate().
+ Don't install pngcp; it conflicts with pngcp in the pngtools package.
+ Minor editing of INSTALL, (whitespace, added copyright line)
+ Added MIPS support (Mandar Sahastrabuddhe <Mandar.Sahastrabuddhe@imgtec.com>).
+ Rebased contrib/intel/intel_sse.patch after the MIPS implementation.

+OPERATING SYSTEM SPECIFIC MIPS MSA DETECTION
+--------------------------------------------
+
+Detection of the ability to execute MIPS MSA on an MIPS processor requires
+operating system support. (The information is not available in user mode.)
+
+HOW TO USE THIS
+---------------
+
+This directory contains C code fragments that can be included in mips/mips_init.c
+by setting the macro PNG_MIPS_MSA_FILE to the file name in "" or <> at build
+time. This setting is not recorded in pnglibconf.h and can be changed simply by
+rebuilding mips/msa_init.o with the required macro definition.
+
+For any of this code to be used the MIPS MSA code must be enabled and run time
+checks must be supported. I.e.:
+
+#if PNG_MIPS_MSA_OPT > 0
+#ifdef PNG_MIPS_MSA_CHECK_SUPPORTED
+
+This is done in a 'configure' build by passing configure the argument:
+
+ --enable-mips-msa=check
+
+Apart from the basic Linux implementation in contrib/mips-msa/linux.c this code
+is unsupported. That means that it is not even compiled on a regular basis and
+may be broken in any given minor release.
+
+FILE FORMAT
+-----------
+
+Each file documents its testing status as of the last time it was tested (which
+may have been a long time ago):
+
+STATUS: one of:
+ SUPPORTED: This indicates that the file is included in the regularly
+ performed test builds and bugs are fixed when discovered.
+ COMPILED: This indicates that the code did compile at least once. See the
+ more detailed description for the extent to which the result was
+ successful.
+ TESTED: This means the code was fully compiled into the libpng test programs
+ and these were run at least once.
+
+BUG REPORTS: an email address to which to send reports of problems
+
+The file is a fragment of C code. It should not define any 'extern' symbols;
+everything should be static. It must define the function:
+
+static int png_have_msa(png_structp png_ptr);
+
+That function must return 1 if MIPS MSA instructions are supported, 0 if not.
+It must not execute png_error unless it detects a bug. A png_error will prevent
+the reading of the PNG and in the future, writing too.
+
+BUG REPORTS
+-----------
+
+If you mail a bug report for any file that is not SUPPORTED there may only be
+limited response. Consider fixing it and sending a patch to fix the problem -
+this is more likely to result in action.
+
+CONTRIBUTIONS
+-------------
+
+You may send contributions of new implementations to
+png-mng-implement@sourceforge.net. Please write code in strict C90 C where
+possible. Obviously OS dependencies are to be expected. If you submit code you
+must have the authors permission and it must have a license that is acceptable
+to the current maintainer; in particular that license must permit modification
+and redistribution.
+
+Please try to make the contribution a single file and give the file a clear and
+unambiguous name that identifies the target OS. If multiple files really are
+required put them all in a sub-directory.
+
+You must also be prepared to handle bug reports from users of the code, either
+by joining the png-mng-implement mailing list or by providing an email for the
+"BUG REPORTS" entry or both. Please make sure that the header of the file
+contains the STATUS and BUG REPORTS fields as above.
+
+Please list the OS requirements as precisely as possible. Ideally you should
+also list the environment in which the code has been tested and certainly list
+any environments where you suspect it might not work.
