 +1.3 pre-beta
 +============
  
 -[1] Creating or decoding a JPEG file that uses the RGB colorspace should now
 +[1] Added support for additional scaling factors (3/8, 5/8, 3/4, 7/8, 9/8, 5/4,
 +11/8, 3/2, 13/8, 7/4, 15/8, and 2) when decompressing.  Currently, the IDCT
 +will not be SIMD-accelerated when using any of these scaling factors.
 +
 +[2] Added SIMD acceleration for performing 4:2:2 upsampling on NEON-capable ARM
 +platforms.  This speeds up the decompression of 4:2:2 JPEGs by 20-25% on such
 +platforms.
 +
++[3] Creating or decoding a JPEG file that uses the RGB colorspace should now
+ properly work when the input or output colorspace is one of the libjpeg-turbo
+ colorspace extensions.
