-[4] Improved performance for non-x86 machines.
+[4] Improved the performance of the C color conversion routines, which are used
+on platforms for which SIMD acceleration is not available.
 
-[5] Added a function to the TurboJPEG API which performs lossless transforms.
-This function uses the same back end as jpegtran, but it performs transcoding
-entirely in memory and allows multiple transforms and/or crop operations to be
-batched together, so the source coefficients only need to be read once.  This
-is useful when generating image tiles from a single source JPEG.

+[11] Refactored the TurboJPEG C API and documented it using Doxygen.  The
+TurboJPEG 1.2 API uses pixel formats to define the size and component order of
+the uncompressed source/destination images, and it includes a more efficient
+version of TJBUFSIZE() that computes a worst-case JPEG size based on the level
+of chrominance subsampling.  The refactored implementation of TurboJPEG/OSS
+now uses the libjpeg memory source and destination managers, which allows the

 now set the unused byte to 0xFF, which allows applications to interpret that
 byte as an alpha channel (0xFF = opaque).
