Changelog for libjpeg8-8.2.2-56.7.i586.rpm :

* Mon Feb 10 2014 Fixed baselibs.conf misspell
* Tue Sep 10 2013 update do 1.3.0:
* 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
* Mon May 27 2013 Build with full RELRO as this library is exposed to possible malicious images.
* Fri May 17 2013 libjpeg62-turbo package created [bnc#807183]
* Mon Aug 13 2012 selfconflicts are not possible, remove it
* Mon Jul 23 2012 Update to version 1.2.1:
* fixed heap overflow [bnc#771791]
* Thu Mar 22 2012 Update to version 1.2.0
* Fixed out-of-bounds read in SSE2 SIMD code
* Added a compile-time macro (LIBJPEG_TURBO_VERSION) that can be used to check the version of libjpeg-turbo against which an application was compiled.
* Added new RGBA/BGRA/ABGR/ARGB colorspace extension constants
* libjpeg-turbo will now correctly decompress erroneous CMYK/YCCK JPEGs whose K component is assigned a component ID of 1 instead of 4.
* Added SIMD routines for RGB-to-grayscale color conversion
* Improved the performance of the C color conversion routines
* Added a function to the TurboJPEG API that performs lossless transforms.
* Added support for 4:4:0 (transposed 4:2:2) subsampling
* Sat Nov 19 2011 add libtool as buildrequire to avoid implicit dependency
* Sat Nov 12 2011 Open all file descriptors with O_CLOEXEC, extended description in the patch file.
* Thu May 19 2011 updated to 1.1.1:
* Fixed a 1-pixel error in row 0, column 21 of the luminance plane generated by tjEncodeYUV().
* libjpeg-turbo\'s accelerated Huffman decoder previously ignored unexpected markers found in the middle of the JPEG data stream during decompression. It will now hand off decoding of a particular block to the unaccelerated Huffman decoder if an unexpected marker is found, so that the unaccelerated Huffman decoder can generate an appropriate warning.
* Fixed a bug in jpeg_read_coefficients() whereby it would not initialize cinfo->image_width and cinfo->image_height if libjpeg v7 or v8 emulation was enabled. This specifically caused the jpegoptim program to fail if it was linked against a version of libjpeg-turbo that was built with libjpeg v7 or v8 emulation.
* Eliminated excessive I/O overhead that occurred when reading BMP files in cjpeg.
