+Changes since the last public release (1.0.13):
 
-  Fixed a bug with reading the length of iCCP profiles (Larry Reeves).
-  Revised makefile.linux, makefile.gcmmx, and others to generate
-    libpng.a, libpngNN.so, libpng.so.NN, and libpngNN/png.h
-  Revised makefile.darwin to remove "-undefined suppress" option.
-  Added checks for gamma and chromaticity values over 21474.83, which exceed
-    the limit for PNG unsigned 32-bit integers when encoded.
-  Revised calls to png_create_read_struct() and png_create_write_struct()
-    for simpler debugging.
-  Revised png_zalloc() so zlib handles errors (uses PNG_FLAG_MALLOC_NULL_MEM_OK)
-  Check chunk_length and idat_size for invalid (over PNG_MAX_UINT) lengths.
-  Check for invalid image dimensions in png_get_IHDR.
-  Added install-shared and install-static targets to all makefiles that make
-    shared libraries.
-  Always do gamma compensation when image is partially transparent.
-  Modified shared-library makefiles to install pkgconfig/libpngNN.pc.
-  Export (with PNGAPI) png_zalloc, png_zfree, and png_handle_as_unknown
-  Removed unused png_write_destroy_info prototype from png.h
-  Eliminated incorrect use of width_mmx from pnggccrd.c in pixel_bytes == 8 case
-  Stopped a double free of palette, hist, and trans when not using free_me.
-  Added makefile.32sunu for Sun Ultra 32 and makefile.64sunu for Sun Ultra 64.
-  Compute background.gray and background_1.gray even when color_type is RGB
-    in case image gets reduced to gray later (Jason Summers).
-  Added PNG_1_0_X macro which can be used to build a 1.0.x-compatible library.
-  Added missing PNGAPI to several function definitions.
-  Check for invalid bit_depth or color_type in png_get_IHDR(), and
-    check for missing PLTE or IHDR in png_push_read_chunk() (Matthias Clasen).
-  Revised iTXt support to accept NULL for lang and lang_key.
-  Compute gamma for color components of background even when color_type is gray.
-  Revised makefiles to put png.h and pngconf.h only in $prefix/include/libpngNN
-  Revised makefiles to make symlink to libpng.so.NN in addition to libpngNN.so
-  Prevent png_zalloc() from trying to memset memory that it failed to acquire.
-  Add typecasts of PNG_MAX_UINT in pngset_cHRM_fixed() (Matt Holgate).
-  Ensure that the right function (user or default) is used to free the
-    png_struct after an error in png_create_read_struct_2().
-  Save the ebx register in pnggccrd.c (Sami Farin)
-  Add "mem_ptr = png_ptr->mem_ptr" in png_destroy_write_struct() (Paul Gardner).
