File Release Notes and Changelog
Release Name: 1.1.6
Notes: Significant changes since release 1.1.5: Improvements: o Performance enhancements to internal string handling. o Save monochrome and grayscale flags in MPC format so that subsequent saving to a monochrome or grayscale format is faster. Bugs fixed: o Memory leak fix to IsPaletteImage(). o Resource tracking (leak) fix to pixel cache code. After processing many images, GraphicsMagick started running slower due to incorrectly using a disk-based pixel cache rather than RAM. o Fixed assertion encountered when displaying a large image using MacOS's X11. o JBIG output was an empty file for some versions of libjbig. o PDF output no longer causes warnings with Ghostscript 8.5. o Added cast to double for integer arguments to pow() which seems necessary since Visual C++ 7.0 and later don't seem to understand that the argument to pow() is a double. o The -convolve option was not working. Convolution was working at the API level. Security Fixes: o Defend against malevolent pnm "P7" files.
