+ Fix for PowerPC platforms lacking AltiVec instructions
+ Fix ABI problem with clang/llvm on aarch64.
+ Fancy upsampling is now supported when decompressing JPEG
images that use 4:4:0 (h1v2) chroma subsampling.
+ If merged upsampling isn't SIMD-accelerated but YCbCr-to-RGB
conversion is, then libjpeg-turbo will now disable merged
upsampling when decompressing YCbCr JPEG images into RGB
or extended RGB output images. This significantly speeds up
the decompression of 4:2:0 and 4:2:2 JPEGs on ARM platforms
if fancy upsampling is not used
(for example, if the -nosmooth option to djpeg is specified.)
+ The TurboJPEG API will now decompress 4:2:2 and 4:4:0 JPEG
images with 2x2 luminance sampling factors and 2x1 or 1x2
chrominance sampling factors.
+ Fixed an unsigned integer overflow in the libjpeg memory manager.
+ Fixed additional negative left shifts and other issues reported
by the GCC and Clang undefined behavior sanitizers when
attempting to decompress specially-crafted malformed JPEG
images. None of these issues posed a security threat, but
removing the warnings makes it easier to detect actual
security issues, should they arise in the future.
+ Fixed an out-of-bounds array reference, introduced by
1.4.902 and detected by the Clang undefined behavior sanitizer,
that could be triggered by a specially-crafted malformed
JPEG image with more than four components. Because the
out-of-bounds reference was still within the same structure,
it was not known to pose a security threat, but removing
the warning makes it easier to detect actual security issues,
should they arise in the future.

+ Fixed an issue whereby a malformed motion-JPEG frame could
cause the "fast path" of libjpeg-turbo's Huffman decoder to
read from uninitialized memory.
+ Added libjpeg-turbo version and build information to the global
string table of the libjpeg and TurboJPEG API libraries.
+ Fixed a couple of issues in the PPM reader that would cause
buffer overruns in cjpeg if one of the values in a binary
PPM/PGM input file exceeded the maximum value defined in the
file's header. libjpeg-turbo 1.4.2 already included a similar
fix for ASCII PPM/PGM files. Note that these issues were not
security bugs, since they were confined to the cjpeg program
and did not affect any of the libjpeg-turbo libraries.
+ Fixed an issue whereby attempting to decompress a JPEG file with
a corrupt header using the tjDecompressToYUV2() function would
cause the function to abort without returning an error and,
under certain circumstances, corrupt the stack. This only
occurred if tjDecompressToYUV2() was called prior to calling
tjDecompressHeader3(), or if the return value from
tjDecompressHeader3() was ignored (both cases represent
incorrect usage of the TurboJPEG API.)
+ The jpeg_stdio_src(), jpeg_mem_src(), jpeg_stdio_dest(),
and jpeg_mem_dest() functions in the libjpeg API will now
throw an error if a source/destination manager has already
been assigned to the compress or decompress object by a
different function or by the calling program.

* Fixed a bug whereby attempting to encode a progressive JPEG
with arithmetic entropy coding (by passing arguments of
-progressive -arithmetic to cjpeg or jpegtran, for instance)
would result in an error, "Requested feature was omitted at
compile time".
* Fixed a couple of issues whereby malformed JPEG images would
cause libjpeg-turbo to use uninitialized memory during
decompression.
* Fixed an error ("Buffer passed to JPEG library is too small")
that occurred when calling the TurboJPEG YUV encoding function
with a very small (< 5x5) source image, and added a unit test
to check for this error.
* etc. see ChangeLog.txt
OBS-URL: https://build.opensuse.org/package/show/graphics/libjpeg-turbo?expand=0&rev=41
* Fixed a Huffman encoder bug that prevented I/O suspension from
working properly.
* 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. Note that the IDCT will not be SIMD-accelerated
when using any of these new scaling factors.
* The tjDecompressToYUV() function now supports the TJFLAG_FASTDCT
flag.
* cjpeg can now be used to generate JPEG files with the RGB
colorspace (feature ported from jpeg-8d.)
* etc. see ChangeLog.txt
- update do 1.3.0:
* Fixed a Huffman encoder bug that prevented I/O suspension from
working properly.

7/8, 9/8, 5/4, 11/8, 3/2, 13/8, 7/4, 15/8, and 2) when
