Apache Commons Compress 1.7 RELEASE NOTES

The Commons Compress team is pleased to announce the
commons-compress-1.7 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 Read-Only support for Snappy compression.
  Issue: COMPRESS-147. Thanks to BELUGA BEHR.
o Read-Only support for .Z compressed files.
  Issue: COMPRESS-243. Thanks to Damjan Jovanovic.
o ZipFile and ZipArchiveInputStream now support reading entries
  compressed using the SHRINKING method. Thanks to Damjan Jovanovic.
o GzipCompressorOutputStream now supports setting the compression
  level and the header metadata (filename, comment, modification time,
  operating system and extra flags)
  Issue: COMPRESS-250. Thanks to Emmanuel Bourg.
o ZipFile and ZipArchiveInputStream now support reading entries
  compressed using the IMPLODE method.
  Issue: COMPRESS-115. Thanks to Emmanuel Bourg.
o ZipFile and the 7z file classes now implement Closeable and can be
  used in try-with-resources constructs.

Fixed Bugs:
o SevenZOutputFile#closeArchiveEntry throws an exception when using
  LZMA2 compression on Java8.  Issue: COMPRESS-241.
o 7z reading of big 64bit values could be wrong.
  Issue: COMPRESS-244. Thanks to Nico Kruber.
o TarArchiveInputStream could fail to read an archive completely.
  Issue: COMPRESS-245.
o The time-setters in X5455_ExtendedTimestamp now set the
  corresponding flags explicitly - i.e. they set the bit if the valus
  is not-null and reset it otherwise.  This may cause
  incompatibilities if you use setFlags to unset a bit and later set
  the time to a non-null value - the flag will now be set.
  Issue: COMPRESS-242.
o SevenZOutputFile would create invalid archives if more than six
  empty files or directories were included.  Issue: COMPRESS-252.
