2.0.6
=====
### Significant changes relative to 2.0.5:
1. Fixed "using JNI after critical get" errors that occurred on Android
platforms when using any of the YUV encoding/compression/decompression/decoding
methods in the TurboJPEG Java API.
2. Fixed or worked around multiple issues with `jpeg_skip_scanlines()`:
- Fixed segfaults or "Corrupt JPEG data: premature end of data segment"
errors in `jpeg_skip_scanlines()` that occurred when decompressing 4:2:2 or
4:2:0 JPEG images using merged (non-fancy) upsampling/color conversion (that
is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.) 2.0.0[6] was a
similar fix, but it did not cover all cases.
- `jpeg_skip_scanlines()` now throws an error if two-pass color
quantization is enabled. Two-pass color quantization never worked properly
with `jpeg_skip_scanlines()`, and the issues could not readily be fixed.
- Fixed an issue whereby `jpeg_skip_scanlines()` always returned 0 when
skipping past the end of an image.
3. The Arm 64-bit (Armv8) Neon SIMD extensions can now be built using MinGW
toolchains targetting Arm64 (AArch64) Windows binaries.
4. Fixed unexpected visual artifacts that occurred when using
`jpeg_crop_scanline()` and interblock smoothing while decompressing only the DC
scan of a progressive JPEG image.
5. Fixed an issue whereby libjpeg-turbo would not build if 12-bit-per-component
JPEG support (`WITH_12BIT`) was enabled along with libjpeg v7 or libjpeg v8
API/ABI emulation (`WITH_JPEG7` or `WITH_JPEG8`.)
