XZ for + Java 1.8 binaries require Java 5. (XZ for Java 1.6 and older + binaries require Java 1.4.) + + If you are using OpenJDK 9 or later, you will need to edit the + "sourcever = 1.5" line in the file "build.properties" before + running "ant". Set it to 1.6 or higher. The default value 1.5 + isn't supported by OpenJDK 9 or later. + + * Add "Automatic-Module-Name" = "org.tukaani.xz". + +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. + + * Make it possible to disable verification of integrity checks in + XZ decompression. It should almost never be used but may be useful + in some rare situations. This feature is available via new + constructors in XZInputStream, SingleXZInputStream, and + SeekableXZInputStream. + + * Add LZMAOutputStream for encoding to raw LZMA (i.e. LZMA1) streams + and to the legacy .lzma format. + +1.5 (2014-03-08) + + * Fix a wrong assertion in BCJ decoders. + + * Use a field instead of reallocating a temporary one-byte buffer + in read() and write() implementations in several classes. + +1.4 (2013-09-22) + + * Add LZMAInputStream for decoding .lzma files and raw LZMA streams. + +1.3 (2013-05-12) + + * Fix a data corruption bug when flushing the LZMA2 encoder or + when using a preset dictionary. + + * Make information about the XZ Block positions and sizes available + in SeekableXZInputStream by adding the following public functions: + - int getStreamCount() + - int getBlockCount() + - long getBlockPos(int blockNumber) + - long getBlockSize(int blockNumber) + - long getBlockCompPos(int blockNumber) + - long getBlockCompSize(int blockNumber) + - int getBlockCheckType(int blockNumber) + - int getBlockNumber(long pos) + - void seekToBlock(int blockNumber) + + * Minor improvements to javadoc comments were made. + +1.2 (2013-01-29) + + * Use fields instead of reallocating frequently-needed temporary + objects in the LZMA encoder. + + * Fix the contents of xz-${version}-sources.jar. + + * Add OSGi attributes to xz.jar. + +1.1 (2012-07-05) + + * The depthLimit argument in the LZMA2Options constructor is + no longer ignored. + + * LZMA2Options() can no longer throw UnsupportedOptionsException. + + * Fix bugs in the preset dictionary support in the LZMA2 encoder. + +1.0 (2011-10-22) + + * The first stable release + |
