+1.1.90 (1.2 beta1)
+==================
+
+[1] Added a JNI wrapper for TurboJPEG/OSS.  See java/README for more details.
+
+[2] TurboJPEG/OSS can now scale down images during decompression.
+
+[3] Added SIMD routines for RGB-to-grayscale color conversion, which
+significantly improves the performance of grayscale JPEG compression from an
+RGB source image.
+
+[4] Improved performance for non-x86 machines.
+
+[5] Added a function to the TurboJPEG API which performs lossless transforms.
+This function uses the same back end as jpegtran, but it performs transcoding
+entirely in memory and allows multiple transforms and/or crop operations to be
+batched together, so the source coefficients only need to be read once.  This
+is useful when generating image tiles from a single source JPEG.
+
+[6] Modified jpgtest to benchmark the new scaled decompression and lossless
+transform features in TurboJPEG/OSS.
+
+[7] Added support for 4:4:0 (transposed 4:2:2) subsampling in TurboJPEG, which
+was necessary in order for it to read 4:2:2 JPEG files that had been losslessly
+transposed or rotated 90 degrees.

+TurboJPEG/OSS JNI Wrapper
+=========================
+
+TurboJPEG/OSS can optionally be built with a Java Native Interface wrapper,
+which allows the TurboJPEG/OSS dynamic library to be loaded and used directly
+from Java applications.  The Java front end for this is defined in several
+classes located under org/libjpegturbo/turbojpeg.  The source code for these
+Java classes is licensed under a BSD-style license, so the files can be
+incorporated directly into both open source and proprietary projects without
+restriction.
+
+TJExample.java, which should also be located in the same directory as this
+README file, demonstrates how to use the TurboJPEG/OSS Java front end to
+compress and decompress JPEG images in memory.
+
+  javac TJExample.java
+
+builds .class files for both the front end and example code.
+
+
+Performance Pitfalls
+--------------------
+
+The TurboJPEG Java front end defines several convenience methods which can
+allocate image buffers or instantiate classes to hold the result of compress,
+decompress, or transform operations.  However, if you use these methods, then
+be mindful of the amount of new data you are creating on the heap.  It may be
+necessary to manually invoke the garbage collector to prevent heap exhaustion
+or to prevent performance degradation.  Background garbage collection can kill
+performance, particularly in a multi-threaded environment (Java pauses all
+threads when the GC runs.)
+
+The Java front end always gives you the option of pre-allocating your own
+source and destination buffers, which allows you to re-use these buffers for
+compressing/decompressing multiple images.  If the image sequence you are
+compressing or decompressing consists of images of the same size, then
+pre-allocating the buffers is recommended.
+
+
+Note for OS X users
+-------------------
+
+/usr/lib, the directory under which libturbojpeg.dylib is installed on Mac
+systems, is not part of the normal Java library path.  Thus, when running a
+Java application that uses TurboJPEG/OSS on Mac systems, you will need to pass
+an argument of -Djava.library.path=/usr/lib to java.
+
+
+Note for Solaris users
+----------------------
+
+/opt/libjpeg-turbo/lib, the directory under which libturbojpeg.so is installed
+on Solaris systems, is not part of the normal Java library path.  Thus, when
+running a Java application that uses TurboJPEG/OSS on Solaris systems, you will
+need to pass an argument of -Djava.library.path=/opt/libjpeg-turbo/lib to java.
+If using a 64-bit data model, then instead pass an argument of
+-Djava.library.path=/opt/libjpeg-turbo/lib/amd64 to use the 64-bit version of
+libturbojpeg.so.
+
+
+Note for MinGW users
+--------------------
+
+When libjpeg-turbo is built with MinGW, the TurboJPEG/OSS dynamic library is
+named libturbojpeg.dll instead of turbojpeg.dll.  This is in keeping with the
+convention of MinGW, and it also avoids a filename conflict when the GCC and
+Visual C++ versions of the libjpeg-turbo SDK are installed on the same system.
+However, the TurboJPEG/OSS JNI wrapper will not work on Windows unless the DLL
+is named turbojpeg.dll.  You can work around this by renaming the DLL or by
+simply changing the LoadLibrary() calls in TurboJPEG.java so that they load
+"libturbojpeg" instead of "turbojpeg".

+How This API Document Is Organized</H1>
+</CENTER>
+This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.<H3>
+Package</H3>
+<BLOCKQUOTE>
+
+<P>
+Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:<UL>
+<LI>Interfaces (italic)<LI>Classes<LI>Enums<LI>Exceptions<LI>Errors<LI>Annotation Types</UL>
+</BLOCKQUOTE>
+<H3>
+Class/Interface</H3>
+<BLOCKQUOTE>
+
+<P>
+Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:<UL>
+<LI>Class inheritance diagram<LI>Direct Subclasses<LI>All Known Subinterfaces<LI>All Known Implementing Classes<LI>Class/interface declaration<LI>Class/interface description
+<P>
+<LI>Nested Class Summary<LI>Field Summary<LI>Constructor Summary<LI>Method Summary
+<P>
+<LI>Field Detail<LI>Constructor Detail<LI>Method Detail</UL>
+Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</BLOCKQUOTE>
+</BLOCKQUOTE>
+<H3>
+Annotation Type</H3>
+<BLOCKQUOTE>
+
+<P>
+Each annotation type has its own separate page with the following sections:<UL>
+<LI>Annotation Type declaration<LI>Annotation Type description<LI>Required Element Summary<LI>Optional Element Summary<LI>Element Detail</UL>
+</BLOCKQUOTE>
+</BLOCKQUOTE>
+<H3>
+Enum</H3>
+<BLOCKQUOTE>
+
+<P>
+Each enum has its own separate page with the following sections:<UL>
+<LI>Enum declaration<LI>Enum description<LI>Enum Constant Summary<LI>Enum Constant Detail</UL>
+</BLOCKQUOTE>
+<H3>
+Tree (Class Hierarchy)</H3>
+<BLOCKQUOTE>
+There is a <A HREF="overview-tree.html">Class Hierarchy</A> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.<UL>
+<LI>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.<LI>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</UL>
+</BLOCKQUOTE>
+<H3>
+Deprecated API</H3>
+<BLOCKQUOTE>
+The <A HREF="deprecated-list.html">Deprecated API</A> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</BLOCKQUOTE>
+<H3>
+Index</H3>
+<BLOCKQUOTE>
+The <A HREF="index-all.html">Index</A> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</BLOCKQUOTE>
+<H3>
+Prev/Next</H3>
+These links take you to the next or previous class, interface, package, or related page.<H3>
+Frames/No Frames</H3>
+These links show and hide the HTML frames.  All pages are available with or without frames.
+<P>
+<H3>
+Serialized Form</H3>
+Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
+<P>
+<H3>
+Constant Field Values</H3>
+The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.
+<P>

+ This method uses the accelerated color conversion routines in

+ suitable for direct video display.  Specifically, if the chrominance
+ components are subsampled along the horizontal dimension, then the width

+ the height of the luminance plane, if the chrominance components are
+ subsampled along the vertical dimension.)  Also, each line of each plane

+ free.  Each lossless transform requires reading and Huffman decoding all
+ of the coefficients in the source image, regardless of the size of the
