Hash: SHA1

The Apache Commons Team is pleased to announce the release of Apache
Commons Compress 1.8.

The Apache Commons Compress Library defines a Java API for working with
ar, cpio, tar, zip, 7z, arj, dump, gzip, pack200, bzip2, lzma, snappy, Z
and xz files.

Version 1.8 is mostly a bugfix release with important fixes for ZIPs
with STORED entries and TAR archives.  It also adds support for some of
the filter methods used in 7z archives.

Source and binary distributions are available for download from the
Apache Commons download site:

http://commons.apache.org/proper/commons-compress/download_compress.cgi

When downloading, please verify signatures using the KEYS file available
at the above location when downloading the release.

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.
