Apache Commons Compress 1.8 RELEASE NOTES

The Commons Compress team is pleased to announce the
commons-compress-1.8 release!

Apache Commons Compress software defines an API for working with
compression and archive formats.  These include: bzip2, gzip, pack200,
lzma, xz, Snappy, traditional Unix Compress and ar, cpio, jar, tar,
zip, dump, 7z, arj.

Changes in this version include:

New features:
o GzipCompressorInputStream now provides access to the same
  metadata that can be provided via GzipParameters when writing
  a gzip stream.
  Issue: COMPRESS-260. 
o SevenZOutputFile now supports chaining multiple
  compression/encryption/filter methods and passing options to
  the methods.
  Issue: COMPRESS-266. 
o The (compression) method(s) can now be specified per entry in
  SevenZOutputFile.
  Issue: COMPRESS-261. 
o SevenZArchiveEntry "knows" which method(s) have been used to
  write it to the archive.
  Issue: COMPRESS-258. 
o The 7z package now supports the delta filter as method. 
o The 7z package now supports BCJ filters for several platforms.
  You will need a version >= 1.5 of XZ for Java to read archives
  using BCJ, though.
  Issue: COMPRESS-257. 

Fixed Bugs:
o BZip2CompressorInputStream read fewer bytes than possible from
  a truncated stream.
  Issue: COMPRESS-253. 
o SevenZFile failed claiming the dictionary was too large when
  archives used LZMA compression for headers and content and
  certain non-default dictionary sizes.
  Issue: COMPRESS-253. 
o CompressorStreamFactory.createCompressorInputStream with
  explicit compression did not honor decompressConcatenated
  Issue: COMPRESS-259. 
o TarArchiveInputStream will now read archives created by tar
  implementations that encode big numbers by not adding a
  trailing NUL.
  Issue: COMPRESS-262. 
o ZipArchiveInputStream would return NUL bytes for the first 512
  bytes of a STORED entry if it was the very first entry of the
  archive.
  Issue: COMPRESS-264. 
o When writing PAX/POSIX headers for TAR entries with
  backslashes or certain non-ASCII characters in their name
  TarArchiveOutputStream could fail.
  Issue: COMPRESS-265. 
o ArchiveStreamFactory now throws a StreamingNotSupported - a
  new subclass of ArchiveException - if it is asked to read from
  or write to a stream and Commons Compress doesn't support
  streaming for the format.  This currently only applies to the
  7z format.
  Issue: COMPRESS-267.
