===============================================================================
* Bug fix: iso_write_opts_set_system_area() with system area types
           1=MIPS Big Endian and 2=MIPS Little Endian caused SIGSEGV.
* Bug fix: SIGSEGV if the path given by iso_image_add_mips_boot_file()
           does not exist in the image at image production time.
* Bug fix: While loading an ISO image: Several reads to malloc
           memory occured with byte index -1. (Found by Valgrind after
           years of operation without visible problems.)
* Bug fix: Closed a memory leak of 32 kB per loaded ISO image.
