It +will now hand off decoding of a particular block to the unaccelerated Huffman +decoder if an unexpected marker is found, so that the unaccelerated Huffman +decoder can generate an appropriate warning. + +[3] Older versions of MinGW64 prefixed symbol names with underscores by +default, which differed from the behavior of 64-bit Visual C++. MinGW64 1.0 +has adopted the behavior of 64-bit Visual C++ as the default, so to accommodate +this, the libjpeg-turbo SIMD function names are no longer prefixed with an +underscore when building with MinGW64. This means that, when building +libjpeg-turbo with older versions of MinGW64, you will now have to add +-fno-leading-underscore to the CFLAGS. + +[4] Fixed a regression bug in the NSIS script that caused the Windows installer +build to fail when using the Visual Studio IDE. + +[5] Fixed a bug in jpeg_read_coefficients() whereby it would not initialize +cinfo->image_width and cinfo->image_height if libjpeg v7 or v8 emulation was +enabled. This specifically caused the jpegoptim program to fail if it was +linked against a version of libjpeg-turbo that was built with libjpeg v7 or v8 +emulation. + +[6] Eliminated excessive I/O overhead that occurred when reading BMP files in +cjpeg. + +[7] Eliminated errors in the output of cjpeg on Windows that occurred when the +application was invoked using I/O redirection (cjpeg <inputfile >output.jpg). + + 1.1.0 ===== @@ -18,7 +54,7 @@ It also ensures that the library can avoid the performance pitfall created by [3] Ported jpgtest.cxx to pure C to avoid the need for a C++ compiler.
