* Licensing change: From version 1.10 onwards, XZ for Java is
under the BSD Zero Clause License (0BSD). 1.9 and older are in
the public domain and obviously remain so; the change only
affects the new releases.
0BSD is an extremely permissive license which doesn't require
retaining or reproducing copyright or license notices when
distributing the code, thus in practice there is extremely
little difference to public domain.
* Mark copyright and license information in the source package so
that it is compliant to the REUSE Specification version 3.2.
* Improve LZMAInputStream.enableRelaxedEndCondition():
+ Error detection is slightly better.
+ The input position will always be at the end of the stream
after successful decompression.
* Support .lzma files that have both a known uncompressed size
and the end marker. Such files are uncommon but valid. The same
issue was fixed in XZ Utils 5.2.6 in 2022.
* Add ARM64 and RISC-V BCJ filters.
* Speed optimizations:
+ Delta filter
+ LZMA/LZMA2 decoder
+ LZMA/LZMA2 encoder (partially Java >= 9 only)
+ CRC64 (Java >= 9 only)
* Changes that affect API/ABI compatibility:
+ Change XZOutputStream constructors to not call the method
public void updateFilters(FilterOptions[] filterOptions).
+ In SeekableXZInputStream, change the method public void
seekToBlock(int blockNumber) to not call the method public
long getBlockPos(int blockNumber).
+ Make the filter options classes final:
~ ARM64Options
~ ARMOptions
~ ARMThumbOptions
~ DeltaOptions
~ IA64Options
~ LZMA2Options
~ PowerPCOptions
~ RISCVOptions
~ SPARCOptions
~ X86Options
* Add new system properties:
+ org.tukaani.xz.ArrayCache sets the default ArrayCache: Dummy
(default) or Basic. See the documentation of ArrayCache and
BasicArrayCache.
+ org.tukaani.xz.MatchLengthFinder (Java >= 9 only) sets the
byte array comparison method used for finding match lengths
in LZMA/LZMA2 encoder: UnalignedLongLE (default on x86-64 and
ARM64) or Basic (default on other systems). The former could
be worth testing on other 64-bit little endian systems that
support fast unaligned memory access.
* Build system (Apache Ant):
+ Building the documentation no longer downloads element-list
or package-list file; the build is now fully offline. Such
files aren't needed with OpenJDK >= 16 whose javadoc can
auto-link to platform documentation on docs.oracle.com. With
older OpenJDK versions, links to platform documentation
aren't generated anymore.
+ Don't require editing of build.properties to build with
OpenJDK 8. Now it's enough to use ant -Djava8only=true. Older
OpenJDK versions are no longer supported because the main
source tree uses Java 8 features.
+ Support reproducible builds. See the notes in README.md.
+ Add a new Ant target pom that only creates xz.pom.
+ Change ant dist to use git archive to create a .zip file.
* Convert the plain text documentation in the source tree to
Markdown (CommonMark).
* The binaries of 1.10 in the Maven Central require Java 8 and
contain optimized classes for Java >= 9 as multi-release JAR.
