## snappy-java-1.1.3 (will be available Early 2017)
* We are waiting contributions of native libraries for varios platforms.
* Run `make native test` and send the result as a pull requset.
* We also test the usability of the newly added bitshuffle API before this release.
* We also test the usability of the newly added BitShuffle API before this release.
## snappy-java-1.1.3-M1 (2017-01-19)
* This is a preview release. Appreciate your feedback.
* Upgraded to snappy 1.1.3 (Minor compression performance improvement)
* Added support for armv5, armv6, armv7, android-arm, aarch64, ppc64
* Added BitShuffle class for better float value compression
* Added BitShuffle (<https://github.com/kiyo-masui/bitshuffle>) class for better primitive array compression
* Using docker-based cross compilers for building native libraries
* AIX, FreeBSD, SunOS, IBM s390x are still using snappy 1.1.2. Your contirbutions of native libraries are welcome. Please send a pull request that contains the changes after runing `make native` in your platform.

* JNI-based implementation to achieve comparable performance to the native C++ version.
* Although snappy-java uses JNI, it can be used safely with multiple class loaders (e.g. Tomcat, etc.).
* Compression/decompression of Java primitive arrays (`float[]`, `double[]`, `int[]`, `short[]`, `long[]`, etc.)
* To improve the compression ratios of these arrays, you can use a fast data-rearrangement implementation ([`BitShuffle`](https://github.com/kiyo-masui/bitshuffle)) before compression

* Portable across various operating systems; Snappy-java contains native libraries built for Window/Mac/Linux (64-bit). snappy-java loads one of these libraries according to your machine environment (It looks system properties, `os.name` and `os.arch`).
* Simple usage. Add the snappy-java-(version).jar file to your classpath. Then call compression/decompression methods in `org.xerial.snappy.Snappy`.
* [Framing-format support](https://github.com/google/snappy/blob/master/framing_format.txt) (Since 1.1.0 version)
