### Significant changes relative to 2.0.2:

  1. Fixed "using JNI after critical get" errors that occurred on Android platforms when passing invalid arguments to certain methods in the TurboJPEG Java API.
  1. 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.)
  1. 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.
  1. Fixed an integer overflow and subsequent segfault that occurred when attempting to compress or decompress images with more than 1 billion pixels using the TurboJPEG API.
  1. 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.
  1. 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.
