 > Additionally, it fixes a number of other issues.  From the release notes:

 > - Fixed a regression in the SIMD feature detection code, introduced by the
 >   AVX2 SIMD extensions (2.0 beta1[1]), that was known to cause an illegal
 >   instruction exception, in rare cases, on CPUs that lack support for CPUID
 >   leaf 07H (or on which the maximum CPUID leaf has been limited by way of a
 >   BIOS setting.)

 > - The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
 >   decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1)
 >   fancy chroma upsampling algorithm, rounding up or down the upsampled
 >   result for alternate pixels rather than always rounding down.  This
 >   ensures that, regardless of whether a 4:2:2 JPEG image is rotated or
 >   transposed prior to decompression (in the frequency domain) or after
 >   decompression (in the spatial domain), the final image will be similar.

 > - Fixed a regression introduced by 2.0 beta1[15] whereby attempting to
 >   generate a progressive JPEG image on an SSE2-capable CPU using a scan
 >   script containing one or more scans with lengths divisible by 16 would
 >   result in an error ("Missing Huffman code table entry") and an invalid
 >   JPEG image.

 > - Fixed an issue whereby tjDecodeYUV() and tjDecodeYUVPlanes() would throw
 >   an error ("Invalid progressive parameters") or a warning ("Inconsistent
 >   progression sequence") if passed a TurboJPEG instance that was previously
 >   used to decompress a progressive JPEG image.

Committed to 2019.02.x and 2019.08.x, thanks.
