+1.3.0
+=====
+
+[1] 'make test' now works properly on FreeBSD, and it no longer requires the
+md5sum executable to be present on other Un*x platforms.
+
+[2] Overhauled the packaging system:
+-- To avoid conflict with vendor-supplied libjpeg-turbo packages, the
+official RPMs and DEBs for libjpeg-turbo have been renamed to
+"libjpeg-turbo-official".
+-- The TurboJPEG libraries are now located under /opt/libjpeg-turbo in the
+official Linux and Mac packages, to avoid conflict with vendor-supplied
+packages and also to streamline the packaging system.
+-- Release packages are now created with the directory structure defined
+by the configure variables "prefix", "bindir", "libdir", etc. (Un*x) or by the
+CMAKE_INSTALL_PREFIX variable (Windows.)  The exception is that the docs are
+always located under the system default documentation directory on Un*x and Mac
+systems, and on Windows, the TurboJPEG DLL is always located in the Windows
+system directory.
+-- To avoid confusion, official libjpeg-turbo packages on Linux/Unix platforms
+(except for Mac) will always install the 32-bit libraries in
+/opt/libjpeg-turbo/lib32 and the 64-bit libraries in /opt/libjpeg-turbo/lib64.
+-- Fixed an issue whereby, in some cases, the libjpeg-turbo executables on Un*x
+systems were not properly linking with the shared libraries installed by the
+same package.
+-- Fixed an issue whereby building the "installer" target on Windows when
+WITH_JAVA=1 would fail if the TurboJPEG JAR had not been previously built.
+-- Building the "install" target on Windows now installs files into the same
+places that the installer does.
+
+[3] Fixed a Huffman encoder bug that prevented I/O suspension from working
+properly.
+
+
+1.2.90 (1.3 beta1)
+==================
+
+[1] 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.
+
+[2] The TurboJPEG dynamic library is now versioned.  It was not strictly
+necessary to do so, because TurboJPEG uses versioned symbols, and if a function
+changes in an ABI-incompatible way, that function is renamed and a legacy
+function is provided to maintain backward compatibility.  However, certain
+Linux distro maintainers have a policy against accepting any library that isn't
+versioned.
+
+[3] Extended the TurboJPEG Java API so that it can be used to compress a JPEG
+image from and decompress a JPEG image to an arbitrary position in a large
+image buffer.
+
+[4] The tjDecompressToYUV() function now supports the TJFLAG_FASTDCT flag.
+
+[5] The 32-bit supplementary package for amd64 Debian systems now provides
+symlinks in /usr/lib/i386-linux-gnu for the TurboJPEG libraries in /usr/lib32.
+This allows those libraries to be used on MultiArch-compatible systems (such as
+Ubuntu 11 and later) without setting the linker path.
+
+[6] The TurboJPEG Java wrapper should now find the JNI library on Mac systems
+without having to pass -Djava.library.path=/usr/lib to java.
+
+[7] TJBench has been ported to Java to provide a convenient way of validating
+the performance of the TurboJPEG Java API.  It can be run with
+'java -cp turbojpeg.jar TJBench'.
+
+[8] cjpeg can now be used to generate JPEG files with the RGB colorspace
+(feature ported from jpeg-8d.)
+
+[9] The width and height in the -crop argument passed to jpegtran can now be
+suffixed with "f" to indicate that, when the upper left corner of the cropping
+region is automatically moved to the nearest iMCU boundary, the bottom right
+corner should be moved by the same amount.  In other words, this feature causes
+jpegtran to strictly honor the specified width/height rather than the specified
+bottom right corner (feature ported from jpeg-8d.)
+
+[10] JPEG files using the RGB colorspace can now be decompressed into grayscale
+images (feature ported from jpeg-8d.)
+
+[11] Fixed a regression caused by 1.2.1[7] whereby the build would fail with
+multiple "Mismatch in operand sizes" errors when attempting to build the x86
+SIMD code with NASM 0.98.
+
+[12] The in-memory source/destination managers (jpeg_mem_src() and
+jpeg_mem_dest()) are now included by default when building libjpeg-turbo with
+libjpeg v6b or v7 emulation, so that programs can take advantage of these
+functions without requiring the use of the backward-incompatible libjpeg v8
+ABI.  The "age number" of the libjpeg-turbo library on Un*x systems has been
+incremented by 1 to reflect this.  You can disable this feature with a
+configure/CMake switch in order to retain strict API/ABI compatibility with the
+libjpeg v6b or v7 API/ABI (or with previous versions of libjpeg-turbo.)  See
+README-turbo.txt for more details.
+
+[13] Added ARM v7s architecture to libjpeg.a and libturbojpeg.a in the official
+libjpeg-turbo binary package for OS X, so that those libraries can be used to
+build applications that leverage the faster CPUs in the iPhone 5 and iPad 4.

-library (TurboJPEG/OSS) that emulates the TurboJPEG API using libjpeg-turbo

-at run time.  Note that the 64-bit libjpeg-turbo packages contain only 64-bit
-binaries, whereas the TurboJPEG/IPP 64-bit packages contained both 64-bit and
-32-bit binaries.  Thus, to replace a TurboJPEG/IPP 64-bit package, install

-You can also build the VirtualGL 2.1.x and TurboVNC 0.6 source code with

+What About libjpeg v9?
+----------------------
+
+libjpeg v9 introduced yet another field to the JPEG compression structure
+(color_transform), thus making the ABI backward incompatible with that of
+libjpeg v8.  This new field was introduced solely for the purpose of supporting
+lossless SmartScale encoding.  Further, there was actually no reason to extend
+the API in this manner, as the color transform could have just as easily been
+activated by way of a new JPEG colorspace constant, thus preserving backward
+ABI compatibility.
+
+Our research (see link above) has shown that lossless SmartScale does not
+generally accomplish anything that can't already be accomplished better with
+existing, standard lossless formats.  Thus, at this time, it is our belief that
+there is not sufficient technical justification for software to upgrade from
+libjpeg v8 to libjpeg v9, and therefore, not sufficient technical justification
+for us to emulate the libjpeg v9 ABI.
+
+=====================================
+In-Memory Source/Destination Managers
+=====================================
+
+By default, libjpeg-turbo 1.3 and later includes the jpeg_mem_src() and
+jpeg_mem_dest() functions, even when not emulating the libjpeg v8 API/ABI.
+Previously, it was necessary to build libjpeg-turbo from source with libjpeg v8
+API/ABI emulation in order to use the in-memory source/destination managers,
+but several projects requested that those functions be included when emulating
+the libjpeg v6b API/ABI as well.  This allows the use of those functions by
+programs that need them without breaking ABI compatibility for programs that
+don't, and it allows those functions to be provided in the "official"
+libjpeg-turbo binaries.
+
+Those who are concerned about maintaining strict conformance with the libjpeg
+v6b or v7 API can pass an argument of --without-mem-srcdst to configure or
+an argument of -DWITH_MEM_SRCDST=0 to CMake prior to building libjpeg-turbo.
+This will restore the pre-1.3 behavior, in which jpeg_mem_src() and
+jpeg_mem_dest() are only included when emulating the libjpeg v8 API/ABI.
+
+On Un*x systems, including the in-memory source/destination managers changes
+the dynamic library version from 62.0.0 to 62.1.0 if using libjpeg v6b API/ABI
+emulation and from 7.0.0 to 7.1.0 if using libjpeg v7 API/ABI emulation.
+
+Note that, on most Un*x systems, the dynamic linker will not look for a
+function in a library until that function is actually used.  Thus, if a program
+is built against libjpeg-turbo 1.3+ and uses jpeg_mem_src() or jpeg_mem_dest(),
+that program will not fail if run against an older version of libjpeg-turbo or
+against libjpeg v7- until the program actually tries to call jpeg_mem_src() or
+jpeg_mem_dest().  Such is not the case on Windows.  If a program is built
+against the libjpeg-turbo 1.3+ DLL and uses jpeg_mem_src() or jpeg_mem_dest(),
+then it must use the libjpeg-turbo 1.3+ DLL at run time.
+
+Both cjpeg and djpeg have been extended to allow testing the in-memory
+source/destination manager functions.  See their respective man pages for more
+details.

 *******************************************************************************
-**     Performance pitfalls
+**     Mathematical Compatibility
+*******************************************************************************
+
+For the most part, libjpeg-turbo should produce identical output to libjpeg
+v6b.  The one exception to this is when using the floating point DCT/IDCT, in
+which case the outputs of libjpeg v6b and libjpeg-turbo are not guaranteed to
+be identical (the accuracy of the floating point DCT/IDCT is constant when
+using libjpeg-turbo's SIMD extensions, but otherwise, it can depend heavily on
+the compiler and compiler settings.)
+
+While libjpeg-turbo does emulate the libjpeg v8 API/ABI, under the hood, it is
+still using the same algorithms as libjpeg v6b, so there are several specific
+cases in which libjpeg-turbo cannot be expected to produce the same output as
+libjpeg v8:
+
+-- When decompressing using scaling factors of 1/2 and 1/4, because libjpeg v8
+   implements those scaling algorithms a bit differently than libjpeg v6b does,
+   and libjpeg-turbo's SIMD extensions are based on the libjpeg v6b behavior.
+
+-- When using chrominance subsampling, because libjpeg v8 implements this
+   with its DCT/IDCT scaling algorithms rather than with a separate
+   downsampling/upsampling algorithm.
+
+-- When using the floating point IDCT, for the reasons stated above and also
+   because the floating point IDCT algorithm was modified in libjpeg v8a to
+   improve accuracy.
+
+-- When decompressing using a scaling factor > 1 and merged (AKA "non-fancy" or
+   "non-smooth") chrominance upsampling, because libjpeg v8 does not support
+   merged upsampling with scaling factors > 1.

-IJG JPEG LIBRARY:  FILE LIST
-
-Copyright (C) 1994-2010, Thomas G. Lane, Guido Vollbeding, D. R. Commander.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Here is a road map to the files in the IJG JPEG distribution.  The
-distribution includes the JPEG library proper, plus two application
-programs ("cjpeg" and "djpeg") which use the library to convert JPEG
-files to and from some other popular image formats.  A third application
-"jpegtran" uses the library to do lossless conversion between different
-variants of JPEG.  There are also two stand-alone applications,
-"rdjpgcom" and "wrjpgcom".
-
-
-THE JPEG LIBRARY
-================
-
-Include files:
-
-jpeglib.h	JPEG library's exported data and function declarations.
-jconfig.h	Configuration declarations.  Note: this file is not present
-		in the distribution; it is generated during installation.
-jmorecfg.h	Additional configuration declarations; need not be changed
-		for a standard installation.
-jerror.h	Declares JPEG library's error and trace message codes.
-jinclude.h	Central include file used by all IJG .c files to reference
-		system include files.
-jpegint.h	JPEG library's internal data structures.
-jchuff.h	Private declarations for Huffman encoder modules.
-jdhuff.h	Private declarations for Huffman decoder modules.
-jdct.h		Private declarations for forward & reverse DCT subsystems.
-jmemsys.h	Private declarations for memory management subsystem.
-jversion.h	Version information.
-
-Applications using the library should include jpeglib.h (which in turn
-includes jconfig.h and jmorecfg.h).  Optionally, jerror.h may be included
-if the application needs to reference individual JPEG error codes.  The
-other include files are intended for internal use and would not normally
-be included by an application program.  (cjpeg/djpeg/etc do use jinclude.h,
-since its function is to improve portability of the whole IJG distribution.
-Most other applications will directly include the system include files they
-want, and hence won't need jinclude.h.)
-
-
-C source code files:
-
-These files contain most of the functions intended to be called directly by
-an application program:
-
-jcapimin.c	Application program interface: core routines for compression.
-jcapistd.c	Application program interface: standard compression.
-jdapimin.c	Application program interface: core routines for decompression.
-jdapistd.c	Application program interface: standard decompression.
-jcomapi.c	Application program interface routines common to compression
-		and decompression.
-jcparam.c	Compression parameter setting helper routines.
-jctrans.c	API and library routines for transcoding compression.
-jdtrans.c	API and library routines for transcoding decompression.
-
-Compression side of the library:
-
-jcinit.c	Initialization: determines which other modules to use.
-jcmaster.c	Master control: setup and inter-pass sequencing logic.
-jcmainct.c	Main buffer controller (preprocessor => JPEG compressor).
-jcprepct.c	Preprocessor buffer controller.
-jccoefct.c	Buffer controller for DCT coefficient buffer.
-jccolor.c	Color space conversion.
-jcsample.c	Downsampling.
-jcdctmgr.c	DCT manager (DCT implementation selection & control).
-jfdctint.c	Forward DCT using slow-but-accurate integer method.
-jfdctfst.c	Forward DCT using faster, less accurate integer method.
-jfdctflt.c	Forward DCT using floating-point arithmetic.
-jchuff.c	Huffman entropy coding for sequential JPEG.
-jcphuff.c	Huffman entropy coding for progressive JPEG.
-jcarith.c	Arithmetic entropy coding.
-jcmarker.c	JPEG marker writing.
-jdatadst.c	Data destination managers for memory and stdio output.
-
-Decompression side of the library:
-
-jdmaster.c	Master control: determines which other modules to use.
-jdinput.c	Input controller: controls input processing modules.
-jdmainct.c	Main buffer controller (JPEG decompressor => postprocessor).
-jdcoefct.c	Buffer controller for DCT coefficient buffer.
-jdpostct.c	Postprocessor buffer controller.
-jdmarker.c	JPEG marker reading.
-jdhuff.c	Huffman entropy decoding for sequential JPEG.
-jdphuff.c	Huffman entropy decoding for progressive JPEG.
-jdarith.c	Arithmetic entropy decoding.
-jddctmgr.c	IDCT manager (IDCT implementation selection & control).
-jidctint.c	Inverse DCT using slow-but-accurate integer method.
-jidctfst.c	Inverse DCT using faster, less accurate integer method.
-jidctflt.c	Inverse DCT using floating-point arithmetic.
-jidctred.c	Inverse DCTs with reduced-size outputs.
-jdsample.c	Upsampling.
-jdcolor.c	Color space conversion.
-jdmerge.c	Merged upsampling/color conversion (faster, lower quality).
-jquant1.c	One-pass color quantization using a fixed-spacing colormap.
-jquant2.c	Two-pass color quantization using a custom-generated colormap.
-		Also handles one-pass quantization to an externally given map.
-jdatasrc.c	Data source managers for memory and stdio input.
-
-Support files for both compression and decompression:
-
-jaricom.c	Tables for common use in arithmetic entropy encoding and
-		decoding routines.
-jerror.c	Standard error handling routines (application replaceable).
-jmemmgr.c	System-independent (more or less) memory management code.
-jutils.c	Miscellaneous utility routines.
-
-jmemmgr.c relies on a system-dependent memory management module.  The IJG
-distribution includes the following implementations of the system-dependent
-module:
-
-jmemnobs.c	"No backing store": assumes adequate virtual memory exists.
-jmemansi.c	Makes temporary files with ANSI-standard routine tmpfile().
-jmemname.c	Makes temporary files with program-generated file names.
-jmemdos.c	Custom implementation for MS-DOS (16-bit environment only):
-		can use extended and expanded memory as well as temp files.
-jmemmac.c	Custom implementation for Apple Macintosh.
-
-Exactly one of the system-dependent modules should be configured into an
-installed JPEG library (see install.txt for hints about which one to use).
-On unusual systems you may find it worthwhile to make a special
-system-dependent memory manager.
-
-
-Non-C source code files:
-
-jmemdosa.asm	80x86 assembly code support for jmemdos.c; used only in
-		MS-DOS-specific configurations of the JPEG library.
-
-
-CJPEG/DJPEG/JPEGTRAN
-====================
-
-Include files:
-
-cdjpeg.h	Declarations shared by cjpeg/djpeg/jpegtran modules.
-cderror.h	Additional error and trace message codes for cjpeg et al.
-transupp.h	Declarations for jpegtran support routines in transupp.c.
-
-C source code files:
-
-cjpeg.c		Main program for cjpeg.
-djpeg.c		Main program for djpeg.
-jpegtran.c	Main program for jpegtran.
-cdjpeg.c	Utility routines used by all three programs.
-rdcolmap.c	Code to read a colormap file for djpeg's "-map" switch.
-rdswitch.c	Code to process some of cjpeg's more complex switches.
-		Also used by jpegtran.
-transupp.c	Support code for jpegtran: lossless image manipulations.
-
-Image file reader modules for cjpeg:
-
-rdbmp.c		BMP file input.
-rdgif.c		GIF file input (now just a stub).
-rdppm.c		PPM/PGM file input.
-rdrle.c		Utah RLE file input.
-rdtarga.c	Targa file input.
-
-Image file writer modules for djpeg:
-
-wrbmp.c		BMP file output.
-wrgif.c		GIF file output (a mere shadow of its former self).
-wrppm.c		PPM/PGM file output.
-wrrle.c		Utah RLE file output.
-wrtarga.c	Targa file output.
-
-
-RDJPGCOM/WRJPGCOM
-=================
-
-C source code files:
-
-rdjpgcom.c	Stand-alone rdjpgcom application.
-wrjpgcom.c	Stand-alone wrjpgcom application.
-
-These programs do not depend on the IJG library.  They do use
-jconfig.h and jinclude.h, only to improve portability.
-
