1.6.0

• Upgraded LZ4 to 1.9.1. Updated the JNI bindings, except for the one for Linux/i386. Decompression speed is improved on amd64.

• Deprecated use of LZ4FastDecompressor of a native instance because the corresponding C API function is deprecated. See the release note of LZ4 1.9.0 for details. Updated javadoc accordingly.

• #134 #137 Changed the module name from org.lz4.lz4-java to org.lz4.java to avoid using - in the module name. (severn-everett, Oliver Eikemeier, Rei Odaira)

1.5.0

• Upgraded LZ4 to 1.8.3. Updated JNI bindings for Linux/amd64, Linux/ppc64le, Linux/s390x, Linux/aarch64, and Mac OS Darwin/x86_64. A speed-up is expected on these platforms. Note that the JNI bindings for Linux/i386 and Win32 still work but are based on old LZ4 r123. Contributions of the JNI bindings for these and other platforms are more than welcome.
