DRC	4a1c2d9	2011-01-28 08:00:10 +0000	[diff] [blame]	1	1.1.0
				2	=====
DRC	fa1d183	2011-01-26 05:35:20 +0000	[diff] [blame]	3
DRC	72abc29	2011-02-18 01:45:24 +0000	[diff] [blame]	4	[1] The algorithm used by the SIMD quantization function cannot produce correct
				5	results when the JPEG quality is >= 98 and the fast integer forward DCT is
DRC	bb4465f	2011-02-18 02:41:03 +0000	[diff] [blame]	6	used. Thus, the non-SIMD quantization function is now used for those cases,
				7	and libjpeg-turbo should now produce identical output to libjpeg v6b in all
				8	cases.
DRC	e1716b8	2011-02-18 03:19:43 +0000	[diff] [blame]	9
DRC	72abc29	2011-02-18 01:45:24 +0000	[diff] [blame]	10	[2] Despite the above, the fast integer forward DCT still degrades somewhat for
				11	JPEG qualities greater than 95, so TurboJPEG/OSS will now automatically use the
				12	slow integer forward DCT when generating JPEG images of quality 96 or greater.
				13	This reduces compression performance by as much as 15% for these high-quality
				14	images but is necessary to ensure that the images are perceptually lossless.
DRC	bb4465f	2011-02-18 02:41:03 +0000	[diff] [blame]	15	It also ensures that the library can avoid the performance pitfall created by
				16	[1].
DRC	2e4d044	2011-02-08 01:18:37 +0000	[diff] [blame]	17
DRC	72abc29	2011-02-18 01:45:24 +0000	[diff] [blame]	18	[3] Ported jpgtest.cxx to pure C to avoid the need for a C++ compiler.
				19
				20	[4] Fixed visual artifacts in grayscale JPEG compression caused by a typo in
DRC	e2f3718	2011-02-17 07:53:46 +0000	[diff] [blame]	21	the RGB-to-chrominance lookup tables.
				22
DRC	240d82f	2011-02-19 00:00:34 +0000	[diff] [blame]	23	[5] The Windows distribution packages now include the libjpeg run-time programs
				24	(cjpeg, etc.)
				25
DRC	db8df01	2011-02-19 00:01:11 +0000	[diff] [blame]	26	[6] All packages now include jpgtest.
DRC	240d82f	2011-02-19 00:00:34 +0000	[diff] [blame]	27
DRC	10e3193	2011-02-25 00:14:12 +0000	[diff] [blame^]	28	[7] The TurboJPEG dynamic library now uses versioned symbols.
				29
				30	[8] Added two new TurboJPEG API functions, tjEncodeYUV() and
				31	tjDecompressToYUV(), to replace the somewhat hackish TJ_YUV flag.
				32
DRC	2d94e26	2011-01-25 06:52:31 +0000	[diff] [blame]	33
DRC	4a1c2d9	2011-01-28 08:00:10 +0000	[diff] [blame]	34	1.0.90 (1.1 beta1)
				35	==================
DRC	766dc5c	2010-10-12 02:50:18 +0000	[diff] [blame]	36
DRC	f38eee0	2011-02-18 07:00:38 +0000	[diff] [blame]	37	[1] Added emulation of the libjpeg v7 and v8 APIs and ABIs. See
DRC	efa618e	2010-10-18 08:41:11 +0000	[diff] [blame]	38	README-turbo.txt for more details. This feature was sponsored by CamTrace SAS.
				39
				40	[2] Created a new CMake-based build system for the Visual C++ and MinGW builds.
DRC	766dc5c	2010-10-12 02:50:18 +0000	[diff] [blame]	41

				43
DRC	01e6909	2011-01-06 01:19:43 +0000	[diff] [blame]	44	[4] jpgtest can now be used to test decompression performance with existing
				45	JPEG images.
DRC	e89bbae	2010-11-12 10:18:08 +0000	[diff] [blame]	46
DRC	d1c281a	2010-11-17 22:44:40 +0000	[diff] [blame]	47	[5] If the default install prefix (/opt/libjpeg-turbo) is used, then
				48	'make install' now creates /opt/libjpeg-turbo/lib32 and
				49	/opt/libjpeg-turbo/lib64 sym links to duplicate the behavior of the binary
				50	packages.
				51
DRC	ec31193	2010-11-22 19:51:42 +0000	[diff] [blame]	52	[6] All symbols in the libjpeg-turbo dynamic library are now versioned, even
				53	when the library is built with libjpeg v6b emulation.
				54
DRC	01e6909	2011-01-06 01:19:43 +0000	[diff] [blame]	55	[7] Added arithmetic encoding and decoding support (can be disabled with
DRC	245cfdf	2010-11-23 17:11:06 +0000	[diff] [blame]	56	configure or CMake options)
DRC	66f97e6	2010-11-23 05:49:54 +0000	[diff] [blame]	57
DRC	9e17f7d	2010-12-10 04:59:13 +0000	[diff] [blame]	58	[8] Added a TJ_YUV flag to TurboJPEG/OSS which causes both the compressor and
				59	decompressor to output planar YUV images.
DRC	fbb6747	2010-11-24 04:02:37 +0000	[diff] [blame]	60
DRC	50c657b	2010-12-14 01:23:16 +0000	[diff] [blame]	61	[9] Added an extended version of tjDecompressHeader() to TurboJPEG/OSS which
				62	allows the caller to determine the type of subsampling used in a JPEG image.
				63
DRC	4a1c2d9	2011-01-28 08:00:10 +0000	[diff] [blame]	64	[10] Added further protections against invalid Huffman codes.
DRC	fa1d183	2011-01-26 05:35:20 +0000	[diff] [blame]	65
DRC	766dc5c	2010-10-12 02:50:18 +0000	[diff] [blame]	66
DRC	4a1c2d9	2011-01-28 08:00:10 +0000	[diff] [blame]	67	1.0.1
				68	=====
DRC	0fbb28e	2010-07-30 17:15:52 +0000	[diff] [blame]	69
				70	[1] The Huffman decoder will now handle erroneous Huffman codes (for instance,
				71	from a corrupt JPEG image.) Previously, these would cause libjpeg-turbo to
				72	crash under certain circumstances.
				73
DRC	025a279	2010-08-07 16:27:56 +0000	[diff] [blame]	74	[2] Fixed typo in SIMD dispatch routines which was causing 4:2:2 upsampling to
				75	be used instead of 4:2:0 when decompressing JPEG images using SSE2 code.
DRC	3095971	2010-08-07 16:06:56 +0000	[diff] [blame]	76
DRC	bdb1288	2010-08-21 21:14:17 +0000	[diff] [blame]	77	[3] configure script will now automatically determine whether the
				78	INCOMPLETE_TYPES_BROKEN macro should be defined.
				79

DRC	c773d10	2010-06-05 06:58:22 +0000	[diff] [blame]	84	[1] 2983700: Further FreeBSD build tweaks (no longer necessary to specify
				85	--host when configuring on a 64-bit system)
DRC	4959787	2010-05-17 20:47:57 +0000	[diff] [blame]	86
DRC	f12c7db	2010-05-18 19:04:47 +0000	[diff] [blame]	87	[2] Created sym. links in the Unix/Linux packages so that the TurboJPEG
				88	include file can always be found in /opt/libjpeg-turbo/include, the 32-bit
				89	static libraries can always be found in /opt/libjpeg-turbo/lib32, and the
				90	64-bit static libraries can always be found in /opt/libjpeg-turbo/lib64.
				91
DRC	4bf3b58	2010-06-05 01:03:23 +0000	[diff] [blame]	92	[3] The Unix/Linux distribution packages now include the libjpeg run-time
				93	programs (cjpeg, etc.) and man pages.
				94
				95	[4] Created a 32-bit supplementary package for amd64 Debian systems which
				96	contains just the 32-bit libjpeg-turbo libraries.
				97
				98	[5] Moved the libraries from /lib32 to /lib in the i386 Debian package.
				99
DRC	df3337c	2010-07-02 09:13:58 +0000	[diff] [blame]	100	[6] Include distribution package for Cygwin
DRC	4bf3b58	2010-06-05 01:03:23 +0000	[diff] [blame]	101
DRC	df3337c	2010-07-02 09:13:58 +0000	[diff] [blame]	102	[7] No longer necessary to specify --without-simd on non-x86 architectures, and
DRC	38ccf85	2010-06-10 19:49:49 +0000	[diff] [blame]	103	unit tests now work on those architectures.
