| Changes since the last public release (1.6.28): |
| |
| Version 1.6.29beta01 [January 12, 2017] |
| Readded "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna). |
| Moved SSE2 optimization code into the main libpng source directory. |
| Configure libpng with "configure --enable-intel-sse" or compile |
| libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it. |
| Simplified conditional compilation in pngvalid.c, for AIX (Michael Felt). |
| |
| Version 1.6.29beta02 [February 22, 2017] |
| Avoid conditional directives that break statements in pngrutil.c (Romero |
| Malaquias) |
| The contrib/examples/pngtopng.c recovery code was in the wrong if |
| branches; the comments were correct. |
| Added code for PowerPC VSX optimisation (Vadim Barkov). |
| |
| Version 1.6.29beta03 [March 1, 2017] |
| Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer). |
| Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in pngrutil.c |
| because Solaris 11 distributes zlib-1.2.8.f that is older than 1.2.8.1. |
| Suppress clang warnings about implicit sign changes in png.c |
