| Changes since the last public release (1.5.16): |
| |
| Version 1.5.17beta01 [June 8, 2013] |
| Removed a redundant test from png_set_IHDR(). |
| Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt) |
| Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt |
| Make ARM NEON support work at compile time (not just configure time). |
| This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when |
| using a compiler that compiles for multiple architectures at one time. |
| Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from |
| pnglibconf.h, allowing more of the decisions to be made internally |
| (pngpriv.h) during the compile. Without this, symbol prefixing is broken |
| under certain circumstances on ARM platforms. Now only the API parts of |
| the optimizations ('check' vs 'api') are exposed in the public header files |
| except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the |
| decision about whether or not to use the optimizations. |
| Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage. |
| Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test |
| on __ARM_NEON__ from configure time to compile time. This breaks symbol |
| prefixing because the definition of the special png_init_filter_functions |
| call was hidden at configure time if the relevant compiler arguments are |
| passed in CFLAGS as opposed to CC. This change attempts to avoid all |
| the confusion that would result by declaring the init function even when |
| it is not used, so that it will always get prefixed. |
| |
| Version 1.5.17rc01 [June 18, 2013] |
| No changes. |
| |
| Version 1.5.17rc02 [June 18, 2013] |
| Revised libpng.3 so that "doclift" can process it. |
