1.4.0

The project page has been moved to https://github.com/lz4/lz4-java. (Adrien Grand, Yann Collet)
groupId and artifactId have been changed from net.jpountz.lz4 and lz4 to org.lz4 and lz4-java, respectively. (Rei Odaira)
#105 LZ4BlockInputStream can read concatenated streams. (Takeshi Yamamuro, Davies Liu)
#99 LZ4FrameInputStream allows EndMark to be incompressible. (Charles Allen)
#95 Added unsafe instance support for aarch64. (Yuqi Gu)
#93 Added unsafe instance support for ppc64le. (Madhusudanan Kandasamy)
#90 LZ4 Java now supports 64-bit JNI build on Solaris. (cndcourt)
#86 Added a pre-built JNI binding for aarch64. (Rocky Zhang)
#85 Added a pre-built JNI binding for s390x. (Rei Odaira)
#84 Added a pre-built JNI binding for ppc64le. (Rei Odaira)
#83 LZ4 Java tries to load a JNI binding from java.library.path first, and then fall back to bundled one. (Jakub Jirutka)
#70 and #89 Avoid over-allocating a buffer in LZ4BlockInputStream. (Marko Topolnik)
#65 Fixed ByteBuffer methods failing to apply arrayOffset() for array-backed buffers. (Branimir Lambov)
#63 All resources are placed under the net.jpountz package to support the maven shade plugin. (Chris Lockfort)
#61 Added LZ4 Frame version 1.5.1 support. (Charles Allen)
#60 Fixed NullPointerException in LZ4Factory and XXHashFactory when they are loaded by the bootstrap classloader. (Yilong Li)
#53 Fixed calling flush on closed LZ4BlockOutputStream. (Will Droste)

lz4 r123
xxhash r37
#49 All compression and decompression routines as well as xxhash can now work with java.nio.ByteBuffer. (Branimir Lambov)
#46 Fixed incorrect usage of ReleasePrimitiveArrayCritical. (Xiaoguang Sun)
#44 Added support for xxhash64. (Linnaea Von Lavia)
#43 The compression level for high compression is now configurable. (Linnaea Von Lavia)
#39 The JAR is now a valid OSGI bundle. (Simon Chemouil)
#33 The implementation based on Java's sun.misc.Unsafe relies on unaligned memory access and is now only used on platforms that support it. (Dmitry Shohov)

lz4 r100
#16 Fix violation of the Closeable contract in LZ4BlockOutputStream: double close now works as specified in the Closeable interface documentation. (Steven Schlansker)
#17 The JNI HC compressor now supports maxDestLen < maxCompressedLength. (Adrien Grand)
#12 Fixed ArrayIndexOutOfBoundsException in the Java HC compressors on highly compressible inputs when srcOff is > 0. (Brian S. O'Neill, @foresteve, Adrien Grand)
Decompressors have been renamed to "safe" and "fast" to reflect changes in the C API. (Adrien Grand)
#18 Added utility methods that take and return (de)compressed byte[]s. (Adrien Grand)

LZ4BlockInputStream does not support mark/reset anymore. (Adrien Grand)
LZ4BlockOutputStream supports a new syncFlush parameter to configure whether the flush method should flush pending data or just flush the underlying stream. (Adrien Grand)
#14 Fixed misspelled API. (Brian S. O'Neill)
#13 Header must be fully read. (Gabriel Ki)

lz4 r88
#7 LZ4Factory.fastestInstance() only tries to use the native bindings if:
- they have already been loaded by the current class loader,
- or if the current class loader is the system class loader. (Adrien Grand)
#5 The native instances unpack a shared library to the temporary directory when they are first used. lz4-java now tries to remove this file on exist but this might fail on systems that don't support removal of open files such as Windows. (Adrien Grand)
Added LZ4Factory.fastestJavaInstance() and XXHash.fastestJavaInstance(). (Adrien Grand)
Added StreamingXXHash32.asChecksum() to return a java.util.zip.Checksum view. (Adrien Grand)
#10 Added LZ4BlockOutputStream which compresses data into fixed-size blocks of configurable size. (Adrien Grand, Brian Moore)
#5 Fixed Windows build. (Rui Gonçalves)
Fixed Mac build. (Adrien Maglo)
#8 Provided pre-built JNI bindings for some major platforms: Windows/64, Linux/32, Linux/64 and Mac Intel/64. (Rui Gonçalves, Adrien Maglo, Adrien Grand)
