XZ for Java release notes
=========================
+1.7 (2017-12-29)
+
+ * Fix LZMA2InputStream.available() which could return a too high
+ value in case of uncompressed LZMA2 chunks. This incorrect
+ value was visible via other available() methods too, for example,
+ XZInputStream.available().
+
+ * Add the ArrayCache API. It's a pool-like API to reuse large byte
+ and int arrays between compressor and decompressor instances.
+ If you are (de)compressing many tiny files in a row, taking
+ advantage of this API can improve performance significantly.
+
1.6 (2016-11-27)
* Fix LZMA2Options.getInputStream to work with a preset dictionary.
