| XZ for Java release notes |
| ========================= |
| |
| 1.8 (2018-01-04) |
| |
| * Fix a binary compatibility regression: XZ for Java 1.7 binaries |
| in the Maven Central require Java 9 which is too new. 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 |
